The consequences of deforestation is

  1. Global warming

  2. Flood

  3. Extinction of flora and fauna

  4. All of the above

Show answer
Correct Option: D
Explanation:
  • Deforestation is when humans remove or clear large areas of forest lands and related ecosystems for non-forest use. These include clearing for farming purposes, ranching, and urban use. In these cases, trees are never re-planted.
  • Plants absorb large amounts of carbon dioxide from the atmosphere. When deforestation takes place it results in an increase in carbon dioxide concentration in the atmosphere which results in global warming.
  • Without trees, rain runs off soil into rivers and streams, raising the water level which leads to floods. Hence deforestation results in the flood.
  • Deforestation also results in the extinction of flora and fauna(plants and animals).
  • Hence The consequences of deforestation are  Global warming, Flood and Extinction of flora and fauna.
  • So, the correct answer is 'All the above'.

Show answer
Correct Option: D
Explanation:
  • Deforestation(disappearance of the forest) is when humans remove or clear large areas of forest lands and related ecosystems for non-forest use. These include clearing for farming purposes, ranching, and urban use. In these cases, trees are never re-planted.
  • Plants absorb large amounts of carbon dioxide from the atmosphere. When deforestation takes place it results in an increase in carbon dioxide concentration in the atmosphere which results in global warming. Hence results in an increase in temperature. Thus deforestation leads to climate change.
  • Without trees, rain runs off soil into rivers and streams i.e soil erosion, raising the water level which leads to floods. Hence deforestation results in the flood.
  • Hence Climate change, Flood and Soil erosion happens if forest disappears.
So, the correct answer is 'All the above'.

  1. Air

  2. Water

  3. Soil

  4. All of the above

Show answer
Correct Option: A
Explanation:
  • Forest is also called the Lung of Earth because they absorb a large amount of carbon dioxide from the atmosphere and release oxygen into the atmosphere.
  • The Amazon rainforest functions as a giant air machine that absorbs a large amount of carbon dioxide, and produces oxygen. More than 20 per cent of the world oxygen is produced in the Amazon Rainforest. 
  • Hence Forest is a purifier of air.
  • So, the correct answer is 'Air'.

Forest is also called as
