Detalles de la respuesta

The Sahel region of Africa is prone to be affected by drought. This semi-arid region, which spans across several African countries, experiences very little rainfall, making it a challenging environment for agriculture and livestock farming. Drought is a common natural disaster in the Sahel region, and it can have serious consequences for the people who live there. When drought occurs, it can lead to crop failures, livestock deaths, and water shortages, which can in turn lead to food insecurity, malnutrition, and even famine. Drought can also exacerbate conflicts over natural resources such as water and land, leading to further instability in the region. Despite the challenges posed by drought, the people of the Sahel have developed a range of coping mechanisms, including pastoralism, rainwater harvesting, and the cultivation of drought-resistant crops. International aid organizations and governments also work to provide assistance to those affected by drought in the Sahel.

The length between two points on a topographical map is 5m. What is the actual distance between them if the scale of the map is 1:50000?

Detalles de la respuesta

To find the actual distance between two points on a topographical map, we need to use the map scale. The map scale tells us the relationship between the distance on the map and the actual distance on the ground. In this case, the scale of the map is 1:50000, which means that one unit of distance on the map represents 50,000 units of distance on the ground. To find the actual distance between the two points on the ground, we need to multiply the distance on the map by the scale factor: Actual distance = Distance on map x Scale factor In this case, the distance on the map is given as 5m. So, we can substitute this value into the formula: Actual distance = 5m x 50000 = 250000m Therefore, the actual distance between the two points is 250000m or 2.5 kilometers.

An ox-bow lake is usually located in a?

Detalles de la respuesta

An ox-bow lake is usually located in a river valley. It is a U-shaped lake that forms when a meandering river erodes its outer banks and forms a new, straighter channel. This leaves behind a crescent-shaped body of water that is separated from the main channel of the river. Ox-bow lakes are typically found in low-lying areas of river valleys, where the river's flow is slow and the sediment load is high. They are formed over time as the river meanders back and forth, eroding the outer banks and depositing sediment on the inside of the bends. Ox-bow lakes are important ecological features, as they provide habitats for a variety of aquatic plants and animals. They are also often used for recreational activities such as fishing, boating, and swimming. While ox-bow lakes can form in other types of landscapes, they are most commonly found in river valleys.

Global warming directly results in?

Detalles de la respuesta

Global warming directly results in melting ice caps and rising sea levels. Global warming refers to the gradual increase in Earth's average surface temperature due to the release of greenhouse gases into the atmosphere. These gases trap heat from the sun, leading to a warming effect on the planet. As the Earth warms, the polar ice caps, which are made up of glaciers and ice sheets, begin to melt, causing a rise in sea levels. This happens because the ice that is melting was previously on land and is now flowing into the oceans. The rise in sea levels can have significant impacts on coastal areas, including flooding and erosion. It can also affect marine life, as changes in sea level can alter ocean currents and temperatures, affecting the habitat and behavior of marine organisms. While global warming may have other indirect impacts, such as changes in weather patterns and ecosystems, it directly results in melting ice caps and rising sea levels, which can have significant and far-reaching consequences for the planet.

The ratio of registered births to the population of women of child-bearing age is known as the?

Detalles de la respuesta

The ratio of registered births to the population of women of child-bearing age is known as the fertility rate. This rate is an important demographic indicator that helps to measure the level of fertility in a population. It is usually expressed as the number of live births per 1,000 women of child-bearing age (usually defined as ages 15-49) in a given year. The fertility rate is influenced by many factors, including cultural, social, economic, and environmental factors. It is an important measure for governments and policy-makers because it can help them to plan for future population growth, to develop healthcare and education policies, and to manage social welfare programs. While there are other rates that are used to measure population health and well-being, such as mortality rate and morbidity rate, the fertility rate is specifically focused on measuring the number of live births in a population.

The major factors that account for the pattern of population distribution in West Africa are?

Detalles de la respuesta

The major factors that account for the pattern of population distribution in West Africa are physical and economic factors. Physical factors include the availability of water, fertile land, and other natural resources that support human habitation. Economic factors, on the other hand, refer to the availability of jobs, economic opportunities, and infrastructure such as roads, hospitals, and schools. In West Africa, areas with abundant natural resources such as arable land, water, and minerals tend to have higher population densities. Coastal areas with easy access to transportation and communication networks also tend to have higher population densities due to increased economic opportunities. Historical and social factors have also played a role in shaping the population distribution patterns in West Africa. For instance, the legacy of colonialism has led to the concentration of people in urban areas, as these were often the sites of administrative and economic activities. Lastly, social and political factors can also influence population distribution in West Africa. For example, conflict and insecurity can force people to migrate to areas perceived to be safer, while government policies and investments can encourage population growth in certain regions.

An important characteristics of the B-horizon in tropical ferruginous soils is the?

Detalles de la respuesta

An important characteristic of the B-horizon in tropical ferruginous soils is the accumulation of oxides. Ferruginous soils are those that are rich in iron, and they are common in tropical regions with a distinct wet and dry season. In these soils, the B-horizon is the layer of soil that lies immediately below the A-horizon, which is the top layer of soil where most of the organic matter is found. The B-horizon is usually less fertile than the A-horizon, and in tropical ferruginous soils, it is characterized by a high concentration of iron oxides, which gives the soil a reddish-brown color. The accumulation of these oxides in the B-horizon is often the result of leaching or eluviation of oxides from the A-horizon due to heavy rainfall, leaving behind the iron oxides in the B-horizon. This accumulation of oxides in the B-horizon can also affect the soil's pH and nutrient availability.

Accelerated soil erosion result from a combination of?

Detalles de la respuesta

Accelerated soil erosion can result from a combination of intensive cultivation and overgrazing. Intensive cultivation refers to farming practices that involve frequent tilling, monoculture cropping, and leaving the soil bare between crops. These practices leave the soil exposed to the elements, making it more susceptible to erosion by wind and water. Overgrazing occurs when livestock consume too much vegetation in a given area, leaving the soil bare and exposed. This makes the soil more vulnerable to erosion by wind and water, which can carry away topsoil and nutrients, leaving behind a less fertile and less productive landscape. When these two factors are combined, the soil is left even more exposed and vulnerable to erosion. Without proper management and conservation practices, accelerated soil erosion can have serious consequences for the environment and for human livelihoods.

Chain survey is most convenient for measurements on ?

Detalles de la respuesta

Chain survey is most convenient for measurements on plains. This is because a chain survey involves measuring distances using a chain, which is a long, narrow measuring tape. The process of measuring distances in a chain survey involves placing the chain on the ground, and walking along the length of the chain to measure the distance between two points. On rocky terrain, the use of a chain may be difficult because it can get snagged on rocks or other obstacles, making it hard to get an accurate measurement. Embankments and irregular slopes can also present challenges for using a chain, as it can be difficult to keep the chain level and straight, which can lead to errors in the measurements. On the other hand, plains are relatively flat and even, making it easier to use a chain to measure distances accurately. The flat terrain allows for the chain to be laid out easily, and the even ground makes it easier to walk along the length of the chain without encountering any obstacles that may cause errors in the measurement. Therefore, chain survey is most convenient for measurements on plains.

Plants that are highly tolerant of drought and can survive in dry habitats are referred to as?

Detalles de la respuesta

Plants that are highly tolerant of drought and can survive in dry habitats are referred to as xerophytes. Xerophytes are plants that have adapted to survive in arid or semi-arid environments where water is scarce. These plants have developed a number of adaptations to reduce water loss and conserve water, such as having thick, waxy leaves, reduced leaf surface area, and deep root systems to access groundwater. Xerophytes are found in a wide range of habitats, from deserts to tundras, and can include cacti, succulents, and many grasses. They are able to survive long periods of drought and extreme temperatures, making them well-suited to their often harsh environments. In contrast, hydrophytes are plants that are adapted to grow in water, mesophytes are plants that grow in moderate moisture environments, and tropophytes are plants that are adapted to grow in a range of temperature and moisture conditions. Therefore, plants that are highly tolerant of drought and can survive in dry habitats are referred to as xerophytes.

Detalles de la respuesta

Inter-regional trade in Nigeria has mostly been promoted by the fact that different regions produce different commodities. Each region in Nigeria has unique resources, such as agricultural products, minerals, and natural resources. By trading with each other, the regions can exchange their surplus goods and satisfy their needs for other products that are not available in their own regions. For example, the northern region of Nigeria is known for producing grains such as millet and sorghum, while the southern region is known for producing cocoa and palm oil. This creates a mutually beneficial trade relationship between the regions, allowing them to specialize in producing what they are best at and trading for what they need. Improved inter-regional transportation and internal security can also facilitate inter-regional trade, but the main driving force behind it is the unique commodities produced in each region.
