  1. Decline in the biodiversity.

  2. Global Warming

  3. Increase in the percentage of pollutants

  4. All of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Deforestation leads to habitat loss (biodiversity decline), increased greenhouse gases (global warming), and reduced air filtration (increased pollutants). All these are well-documented impacts.

Multiple choice commercial studies forests: our lifeline afforestation deforestation and its effect deforestation

Which of the following disaster is caused by deforestation?

  1. Infertility of soil

  2. Climatic change

  3. Loss of flora and fauna

  4. All of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Deforestation causes soil degradation, alters local and global climates, and destroys habitats for flora and fauna. All these are significant environmental disasters resulting from forest loss.

Multiple choice commercial studies forests: our lifeline afforestation deforestation and its effect deforestation

Identify the incorrect statement.

  1. Forest prevents soil erosion.

  2. Forest influences climate and water cycle.

  3. Soil helps forest to regenerate.

  4. Plants and animals in the forest are not dependent on one another.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Plants provide shelter for animals and they make oxygen for the animals to live. When animals die they decompose and become natural fertilizer plants. Plants depend on animals for nutrients, pollination and seed dispersal. 
  • Hence Plants and animals in the forest are dependent on one another.
  • Hence the given statement Plants and animals in the forest are not dependent on one another is a wrong statement.
  • So, the correct answer is 'Option D'.
Multiple choice evs - i forests: our lifeline afforestation deforestation and its effect deforestation

One of the main causes of the silting of big dams is?

  1. Deforestation in the catchments area

  2. Increase in the population of wild animals in the forests around the dam

  3. Insufficient rainfall

  4. Excessive evaporation of water

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

When forests in the catchment area are removed, soil erosion increases significantly. This eroded soil is washed into rivers and dams, leading to the accumulation of sediment, known as silting.

Forests improve _________.

  1. Pollution

  2. Population

  3. Rainfall

  4. None of these

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Forests plays signicant role in improving rainfall. The growing plants used to intake lot of amount of moisture from the soil and release  90% of the moisture in the atmosphere which after condensation created precipitation. On the othe hand after rainfall they used to hold the moisture in it and aslo heps the soil to hold the moisture. In this ways a cycle goes on and forest improved rainfall.

Multiple choice evs - i forests: our lifeline afforestation deforestation and its effect deforestation

What is deforestation?

  1. Clearing of forests

  2. Planting of more trees

  3. Grazing of animals in forest area

  4. None of the above

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Deforestation is excessive cutting of the trees. it clears the land area which can cause the floods or may lead to infertility of the land. The most dramatic impact is a loss of habitat for millions of species. Seventy percent of Earth's land animals and plants live in forests, and many cannot survive the deforestation that destroys their homes.

So, the correct answer is option A.
