Birth and death rates are often stated as the number of cases per?

1 000 per year

1 000 000 per year

10 per year

100 per year

Answer Details

Birth and death rates are often stated as the number of cases per 1,000 per year. This means that the number of births or deaths in a population is divided by the total population and then multiplied by 1,000 to get the rate per 1,000 people. For example, if there are 10 births in a population of 1,000 people in a year, the birth rate would be 10/1,000 x 1,000 = 10 per 1,000 per year. This makes it easier to compare birth and death rates across different populations with varying sizes.

Which of the following is of great importance to the existence of plants?

Metal scarps

Industrial effluent

Carbon (IV) oxide

Carbon (II) oxide

Answer Details

Carbon (IV) oxide is of great importance to the existence of plants. Plants, like all living organisms, require certain elements to survive and grow. One of the most important elements for plants is carbon, which they obtain from carbon dioxide (CO2) in the atmosphere. During photosynthesis, plants use energy from the sun to convert carbon dioxide and water into glucose (sugar) and oxygen. This process not only allows plants to produce their own food, but it also releases oxygen into the atmosphere, which is necessary for the survival of animals and humans. Industrial effluent and metal scraps are pollutants that can harm plants and other living organisms, and they are not necessary for the existence of plants. Carbon (II) oxide does not exist in nature; the correct term is carbon monoxide, which is a toxic gas that can be lethal to plants and animals at high concentrations.

The rock type whose principal constituents can be seen without magnification is?

limestone

basalt

sandstone

granite

Answer Details

The rock type whose principal constituents can be seen without magnification is granite. Granite is a common type of intrusive igneous rock that is composed of visible minerals such as quartz, feldspar, and mica. When viewed with the naked eye, the individual minerals in granite can be easily distinguished from one another, and their colors and shapes can be observed. This is because granite typically has a coarse-grained texture, which means that its mineral grains are large enough to be visible to the naked eye. In contrast, rocks such as limestone, basalt, and sandstone often have a finer-grained texture, which means that their mineral grains are too small to be seen without magnification. Therefore, granite is the rock type that is most easily recognizable without the need for magnification.

sensible tillage, crop rotation and mulching

Answer Details

Soil conservation is the practice of protecting and preserving soil from degradation or loss. It involves preventing soil erosion, improving soil fertility, and preserving soil structure. Soil conservation can be achieved through various methods, including sensible tillage, crop rotation, and mulching. Sensible tillage involves tilling the soil in a way that minimizes soil erosion and compaction. Crop rotation involves rotating crops on a piece of land to improve soil fertility and reduce the risk of soil-borne diseases. Mulching involves covering the soil with organic matter, such as leaves, straw or compost, to reduce water evaporation and soil erosion, and to improve soil fertility. These methods help to maintain the quality and productivity of the soil, thereby preserving it for future generations.

Soil texture is determined primarily by?

profile horizons

major components

particle sizes

nutrient status

Answer Details

Soil texture is determined primarily by the particle sizes of the soil. Soil texture refers to the relative proportion of sand, silt, and clay particles in the soil. These particle sizes affect the ability of the soil to retain water and nutrients, as well as its drainage properties. Sand particles are the largest and provide good drainage but have low water-holding capacity. Clay particles are the smallest and provide high water-holding capacity but poor drainage. Silt particles fall in between sand and clay particles in terms of size and characteristics. The combination of these particle sizes in the soil determines its texture, which is important for agriculture and other land uses. Therefore, while profile horizons, major components, and nutrient status are also important factors in soil characteristics, the particle sizes of the soil are the primary determinant of its texture.

The exploitation of timber in equatorial Africa causes?

soil erosion

environmental pollution

less rainfall run-off

high cost of forest products

Answer Details

The exploitation of timber in equatorial Africa can cause soil erosion. This is because trees play a vital role in preventing soil erosion. When trees are cut down, the soil is exposed to the elements, and heavy rain can wash away the soil, leading to erosion. Additionally, the removal of trees reduces the amount of organic matter in the soil, making it less fertile and harder for new vegetation to grow. As a result, timber exploitation can lead to long-term environmental degradation and reduce the overall health of the ecosystem.

Answer Details

A doline is associated with a Karst valley. A doline is a funnel-shaped depression in a Karst landscape that is formed as a result of the dissolution of limestone or other soluble rocks. When groundwater dissolves the rock, it creates underground caverns that can eventually collapse and form a doline on the surface. Therefore, dolines are typically found in Karst landscapes, which are characterized by the dissolution of soluble rocks and the formation of distinctive surface and subsurface features such as sinkholes, caves, and underground rivers.

The two primary causes of ocean currents are?

differential algae development and sunlight penetration

differential salinity and temperature variation

variation in evaporation and coral development

location of settlements and sea-level pressure

Answer Details

Ocean currents are primarily caused by two factors: differential salinity and temperature variation. The difference in salinity and temperature between two areas of water creates a difference in density, which then drives the movement of water. Warm water is less dense than cold water, and water with a higher salt concentration is denser than water with a lower salt concentration. These differences in density drive the movement of water from one area to another, creating ocean currents.

When contours are equally spaced, the slope is said to be even. This means that the difference in elevation between each contour line is the same. For example, if contour lines on a map are drawn at 10-meter intervals, an even slope means that the elevation difference between each contour line is 10 meters. An even slope can be a gentle slope or a steep slope, but what makes it even is the uniform spacing between contour lines.

.The area likely to experience seasonal flooding lies

above a 120-metre contour

between 105 and 120-metre contours

between 105 and 135-metre contours

below a 105-metre contour

Answer Details

The area likely to experience seasonal flooding lies below a 105-metre contour. The contour refers to an imaginary line on a map that connects all points of the same elevation. In this case, the contour is measured in meters above sea level. Areas that are located below the 105-metre contour are usually closer to sea level, which makes them more susceptible to flooding. During periods of heavy rainfall or high tides, water can easily overflow from nearby rivers, lakes, or oceans and inundate low-lying areas. In contrast, areas that are located above the 120-metre contour are generally at a higher elevation and are less likely to experience flooding. Therefore, the area likely to experience seasonal flooding lies below a 105-metre contour.

Answer Details

Lowland plains may lead to an area being densely populated. This is because lowland plains are usually flat and have fertile soils, which make them ideal for agriculture. As a result, people are attracted to these areas for farming and other economic activities, such as trading and manufacturing. In addition, lowland plains often have access to water sources such as rivers and lakes, which also support agriculture and other economic activities. These factors, combined with the ease of transportation and communication due to the flat terrain, make lowland plains attractive for settlement and development. Therefore, while high plateaux, rugged mountains, and active volcanoes may also have their own unique attractions and opportunities, lowland plains are more likely to be densely populated due to their suitability for agriculture and other economic activities.
