The process of getting water to needed areas for farming is known as:

Extraction
Drought
Deforestation
Irrigation

Correct Answer

A. Irrigation

Explanation

Irrigation is the correct answer because it refers to the process of supplying water to agricultural land in order to promote the growth of crops. It involves the use of various techniques such as canals, ditches, and sprinklers to distribute water efficiently to the areas where it is needed for farming. Extraction, drought, and deforestation are not directly related to the process of supplying water for farming.

Bacteria living in the water from certain soils and vegetation contribute to a lack of safe drinking water in Africa. This is an example of:

Water Pollution
Irrigation
Extraction
Drought

Correct Answer

A. Water Pollution

Explanation

The presence of bacteria in the water from certain soils and vegetation can contaminate the water and make it unsafe for drinking. This contamination of water by bacteria is a form of water pollution. Water pollution refers to the introduction of harmful substances or microorganisms into water bodies, making it unfit for human consumption or for the survival of aquatic organisms. In this case, the bacteria present in the water contribute to the lack of safe drinking water in Africa.

Click on the boxes that describe reasons for desertification in Africa.

Increasing population
Drought
Civil wars
Over-grazing of animals
Partitioning
Arid climate
Deforestation
Subsistence farming
Water pollution

Correct Answer(s)

A. Increasing population
A. Drought
A. Over-grazing of animals
A. Arid climate
A. Deforestation

Explanation

Desertification in Africa can be attributed to several factors. Firstly, the increasing population puts pressure on the land, leading to overexploitation and degradation. Secondly, drought is a common occurrence in many parts of Africa, causing soil moisture depletion and making the land more susceptible to desertification. Over-grazing of animals is another significant factor as it leads to the removal of vegetation cover, exposing the soil to erosion. The arid climate prevalent in many regions of Africa exacerbates the desertification process. Deforestation, particularly for agricultural purposes, further contributes to the loss of vegetation and soil degradation. These factors collectively contribute to the desertification problem in Africa.

Click on the boxes that describe reasons for Deforestation.

To clear land for farming
To create natural habitats for animals
To keep up with growing populations
To sell timber products for profit
For irrigation
To help the environment

Correct Answer(s)

A. To clear land for farming
A. To keep up with growing populations
A. To sell timber products for profit

Explanation

Deforestation occurs primarily to clear land for farming, as agricultural activities require large areas of land. Additionally, deforestation is driven by the need to keep up with growing populations, as more land is needed to accommodate the increasing demand for resources. Another significant reason for deforestation is to sell timber products for profit, as the logging industry is a lucrative business. These reasons explain the causes behind deforestation and the negative impact it has on the environment.

Click on the boxes that describe the effects of water pollution in sub-Saharan Africa.

Lack of safe drinking water
Drought
Deforestation
Decreased economic growth
Sickness, disease, and death of people and animals
Increased vegetation
Erosion and flash floods

Correct Answer(s)

A. Lack of safe drinking water
A. Decreased economic growth
A. Sickness, disease, and death of people and animals

Explanation

Water pollution in sub-Saharan Africa has several negative effects. Firstly, it leads to a lack of safe drinking water, which poses a serious health risk to the population. Additionally, water pollution contributes to decreased economic growth as it affects agricultural productivity and limits access to clean water for industries. Moreover, the contamination of water sources results in sickness, disease, and death of both people and animals, further exacerbating the public health crisis in the region.
