Deforestation

Question 1

Leaching

Answer 1

When trees are removed nutrients get leached away but don’t get replaced leaving infertile soil

Question 2

Disturbing the water cycle

Answer 2

1. Trees stop rainwater going into the river too quickly. When cut down it can lead to flooding
2. Transpiration releases some rainwater into the atmosphere making local climate drier

Question 3

Disturbing balance of CO2 and O2

Answer 3

Forests take up CO2 by photosynthesis, store it in wood and slowly releases as it decomposes. When cut down/burnt CO2 is released and contributes to global warming

Question 4

Soil erosion

Answer 4

Tree roots hold the soil together and when they are removed the soil is eroded leaving infertile ground
