Sugar Plantations in Africa are most highly developed in the lowlands of Natal and Mozambique. These two regions have warm climates and fertile soils, which are ideal conditions for growing sugarcane, a plant used to make sugar. The lowlands of Natal and Mozambique are also close to ports, which makes it easier to export the sugar that is produced. Because of these factors, the sugar industry has flourished in these regions, making them the most highly developed areas for sugar production in Africa.

One way to overcome the problem of irregular levels of water in river transport is by building locks and canals. Locks are structures that allow boats and ships to pass from one water level to another. They work by closing and filling with water, which raises or lowers the water level inside the lock to match the water level on the other side. This allows boats and ships to safely navigate through areas where the water level is different. Canals, on the other hand, are man-made waterways that are built to connect two waterways or to bypass a stretch of river with difficult navigational conditions. By providing a controlled and stable water environment, locks and canals can greatly improve the reliability and efficiency of river transport.

To calculate the birth rate of a country, we need to divide the number of registered births by the total population of the country and then multiply by 100 to get a percentage. In this case, the number of registered births is 3,000,000, and the total population of the country is 150,000,000. So the birth rate is (3,000,000 / 150,000,000) x 100, which simplifies to 2%. Therefore, the answer is%, meaning that the birth rate of the given country is 2%.

Soil texture is primarily determined by the particle sizes of the mineral components in the soil. These mineral particles can range in size from large rocks to tiny clay particles. The three main particle size classes that determine soil texture are sand, silt, and clay. Sand particles are the largest, ranging in size from 0.05 to 2.0 millimeters. Silt particles are smaller, ranging from 0.002 to 0.05 millimeters. Clay particles are the smallest, less than 0.002 millimeters in size. The proportion of these particle sizes in the soil determines its texture. Soil texture is an important factor that affects many soil properties, including water-holding capacity, drainage, nutrient availability, and the ability of roots to grow. Soil texture is also used as a basis for soil classification, with different textures having different names, such as sandy loam, clay loam, and silty clay.

The rock that is formed by wood subjected to pressure and heat is called "lignite". Lignite is a type of coal that is considered the lowest rank of coal due to its relatively low heat content and carbon content. Lignite is formed from partially decomposed plant material that has been subjected to increasing amounts of pressure and heat over time. As the plant material becomes buried and compressed, it eventually transforms into lignite through a process called coalification. Therefore, lignite is a sedimentary rock that is formed from the compressed and heated remains of plants, including wood. It is typically brownish-black in color and has a relatively low density compared to other types of coal.

The desert country with high population density supported by irrigation is Egypt. Egypt is located in the northeastern part of Africa and is mostly covered by the Sahara desert. Despite the desert conditions, Egypt has a high population density due to the Nile river that runs through the country. The Nile river provides water for irrigation, which has allowed for the cultivation of crops and supported the growth of a population in what would otherwise be an uninhabitable region. The ancient Egyptians were able to take advantage of the Nile's seasonal floods and develop a complex system of canals and irrigation to grow crops. Today, modern irrigation techniques have allowed Egypt to continue to support a high population density and grow crops such as wheat, cotton, and fruits.

A non-renewable resource is a resource that cannot be easily replenished or regenerated. An example of a non-renewable resource is mineral, such as coal, oil, and natural gas. These resources are formed over millions of years and are finite, meaning they will eventually run out. Unlike renewable resources, like wind and solar power, which can be replenished, non-renewable resources are being consumed faster than they can be replaced. This is why it's important to use these resources wisely and find alternative energy sources to preserve them for future generations.

The Udi hills can be considered as a good example of a cuesta landscape in Nigeria. A cuesta is a type of landform that is formed from the erosion of layered rocks. It is characterized by a gentle slope on one side and a steep slope on the other side. The Udi hills have this characteristic and are composed of sandstone and shale, which have been tilted and eroded over time, forming the cuesta landscape. This area is also known for its scenic beauty and rich cultural heritage, making it an interesting place to visit.

A common feature of Forcados, Bonny, and Eket in the Niger Delta is that they are all terminals for oil companies. These three locations are major hubs for the extraction, transportation, and export of crude oil in the region. Forcados, Bonny, and Eket are all situated along the coast of the Niger Delta, which is home to vast reserves of crude oil. Oil companies have established facilities at these locations to extract crude oil from the ground, transport it via pipelines or tankers, and export it to other parts of the world. The oil industry is a crucial part of the economy of the Niger Delta, and Forcados, Bonny, and Eket are all key players in this industry. While fishing is an important activity in the Niger Delta, these locations are not primarily known for their fishing ports. Similarly, while natural gas exports are an important part of the region's economy, Forcados, Bonny, and Eket are not the only locations where this takes place. Finally, while export processing zones do exist in the Niger Delta, this is not a defining characteristic of these three locations.

A cirque is an example of a landform produced by glaciation. A cirque is a bowl-shaped depression on a mountainside with steep walls formed by glacial erosion. As a glacier moves down a mountain, it erodes the bedrock through a combination of abrasion and plucking. Abrasion occurs when the glacier grinds against the bedrock and wears it away, while plucking occurs when the glacier freezes onto the bedrock and pulls it away as the glacier moves downhill. Over time, this erosion can form a deep, steep-sided hollow or cirque on the mountainside. Cirques are often the starting point for the formation of other glacial landforms, such as u-shaped valleys and horn peaks. As a glacier continues to erode the mountainside, it can deepen and widen the cirque, creating a u-shaped valley. If multiple glaciers erode back-to-back cirques on a single mountain, it can leave behind a horn peak or a jagged, triangular peak at the mountain summit. Overall, cirques are a classic example of a landform produced by the slow, powerful forces of glaciation.

The standard time of a country is determined by the longitude of its location on the Earth. A time zone is a region that has the same standard time, and time zones are typically defined as an offset from the Coordinated Universal Time (UTC). In this case, the country has a standard time of GMT + 1 hour, which means it is one hour ahead of the UTC. The longitude that corresponds to this time zone is the one located 15° east of the Prime Meridian, which runs from the North Pole to the South Pole and passes through the Royal Observatory in Greenwich, London, England. So, the local time adopted by the country is 15°E.

In surveying, the prismatic compass is primarily used to obtain bearings of features. It is a type of compass that has a prism attached to it, which allows the user to simultaneously see the compass needle and the object being sighted through the prism. By aligning the compass with the object and reading the bearing, the prismatic compass can determine the direction or angle of the object relative to magnetic north. This information is crucial for creating accurate maps and plans, as well as for navigating and orienting oneself in the field. While a prismatic compass may be capable of measuring other factors, such as horizontal distances or inclinations, its primary function is to obtain bearings of features.

Among the options given, the most influential factor in the location of textile and footwear industries is abundant cheap labor. Textile and footwear industries require a large labor force to produce goods at a low cost. If a country has a large supply of labor willing to work for low wages, it can attract textile and footwear industries to set up factories in its territory. This is because labor is usually the largest cost for these industries, and a country with cheap labor can offer cost advantages to manufacturers. Raw materials are also important for these industries, but they can be imported from other countries if they are not available locally. Energy supply and low interest rates may also affect the cost of production, but they are less critical factors than the availability of cheap labor. In summary, countries with a large supply of cheap labor have an advantage in attracting textile and footwear industries because they can offer low production costs to manufacturers, making their products more competitive in the global market.

The igneous rock with distinct grains of mica, feldspar, and quartz is granite. Granite is a type of igneous rock that is formed by the cooling and solidification of magma or lava. It is composed of several minerals, including quartz, feldspar, and mica. These minerals give granite its characteristic speckled appearance and make it a popular choice for building and decorative purposes. Mica is a shiny mineral that appears in thin, flat sheets and gives granite its distinctive glittery look. Feldspar is a group of minerals that are very common in igneous rocks and make up the majority of granite's composition. Quartz is a hard, mineral that is often found in igneous rocks and contributes to granite's durability. In summary, if you find an igneous rock with distinct grains of mica, feldspar, and quartz, it is most likely granite.

Lowland plains may lead to an area being densely populated because they provide fertile land for agriculture, easy transportation and communication routes, and access to water sources. Lowland plains are typically flat, which makes it easier to build roads, buildings, and other infrastructure, and also makes it more conducive for farming. In addition, lowland areas tend to have more moderate climates and are less prone to natural disasters, such as floods or landslides, which can make them more attractive to settlers. Overall, the combination of fertile land, ease of transportation and communication, access to water sources, and favorable climate can all contribute to high population density in lowland areas.

If M is due west of station N, it means that M is directly to the left of N when you are facing North. In terms of bearings, due west corresponds to a bearing of 270°. To understand why, imagine standing at station N and facing North. You can think of bearings as angles measured in a clockwise direction from North. A bearing of 0° would correspond to due North, a bearing of 90° would correspond to due East, and so on. Since M is due west, it is directly to your left when you are facing North, which means it is 90 degrees to your left. If you add 90° to the 180° bearing of due South, you get 270°, which is the bearing of M from N. So, the correct answer is 270°.

The best way to prevent a watershed from degradation is through forest reservation. Watersheds are areas of land that drain into a common body of water, such as a river or a lake. Forest reservation refers to the process of setting aside and protecting areas of forest from human activities that may cause harm to the ecosystem. Forests are important in watersheds because they help regulate water flow, filter pollutants, and provide habitat for wildlife. Fuel wood extraction and crop production can cause harm to watersheds if they are not managed sustainably. Fuel wood extraction can lead to deforestation, soil erosion, and loss of biodiversity, which can in turn impact water quality and quantity. Crop production can lead to the use of fertilizers and pesticides that can runoff into the water, causing pollution. Inter-basin transfer is the process of diverting water from one basin to another. While it can be a solution to water scarcity, it can also have negative impacts on watersheds, including altering natural water flow, disrupting ecosystems, and reducing water availability downstream. In summary, forest reservation is the best way to prevent watershed degradation as it helps to maintain the natural ecosystem functions that are important for water quality and quantity.

A population with low birth and death rates generally presents an aging population structure, meaning there are more older people compared to younger people. This results in an inverted population pyramid, where the base is narrow at the younger ages and wider at the older ages. This occurs because people are living longer and there are fewer newborns to replace them. This population structure has implications for social and economic systems, as it may lead to increased demands for healthcare and pension systems.

The most suitable statistical diagram to show spatial distribution of production is a dot map. A dot map is a type of map that uses dots to represent the quantity or density of a particular feature across a geographic area. In the case of production data, each dot can represent a certain amount of production, and the density of the dots can show areas with high or low production levels. This allows for a clear visual representation of where production is concentrated and where it is less prominent. Pie charts, divided circles, and line graphs are not suitable for showing spatial distribution of production. A pie chart is used to show proportions of a whole, while a divided circle is similar to a pie chart but is divided into more than one category. These charts are best suited for displaying data where the whole is made up of distinct categories, rather than for geographic data. A line graph, on the other hand, is used to show trends over time, and is not well-suited for displaying spatial data.

The highest category of rural settlement is a village. A village is a small, rural community that typically consists of a group of houses and other buildings, surrounded by farmland. People in a village often have close-knit relationships and rely on each other for support. Villages often have a central area where people gather for social events and activities, such as a village green or town square. Villages may also have basic amenities such as a school, a post office, and a general store. In comparison, a homestead refers to a house and the surrounding land that is used for farming or other agricultural purposes. A hut is a small, simple dwelling, often made of natural materials like mud or thatch. A hamlet is a small settlement, similar to a village, but with a smaller population and fewer amenities.

In surveying, it is best dealt with by laying offsets. This means that instead of measuring the exact distance or angle to an object that may obstruct the line of sight, the surveyor will measure to a point slightly to the side of the obstruction and then use that measurement to calculate the true distance or angle. This allows the surveyor to gather accurate information without having to physically remove the obstruction or avoid it altogether. By laying offsets, the surveyor can ensure that the survey results are accurate and reliable.
