8. Explain how deforestation leads to reduced rainfall.
Answers
How deforestation leads to reduced rainfall?
Deforestation leads to reduced rainfall because it reduces the natural recycling of moisture from the soils. This recycling takes place through vegetation and returns to the form of rainfall. According to studies, when pastures replace forests, water recycling gets affected, leading to a reduction in humidity in the atmosphere, which impacts precipitation.
1. Deforestation also means that the level of carbon dioxide in the atmosphere increases, giving rise to global warming. An increase in global warming has adverse effects on the natural water cycle.
2. Deforestation also leads to floods. This is because the water holding capacity of the soil is dependent on the number of trees.
3. As the number of tresses reduces, the soil structure changes and the soil particles held firmly get disturbed. As a result, when there is heavy rainfall, the rainwater does not seep down into the ground and is not absorbed by the trees. Hence, it leads to flooding.
Answer:
This is the answer...
Explanation:
i) Due to deforestation, the amount of CO2 in the atmosphere will be increased.
ii) CO2 traps the heat rays reflected by the Earth, the amount of heat (temperature) will be increased on the Earth's surface.
iii) This causes global warming and disturbs the water cycle.
iv) As a result the amount of rainfall is reduced.
