What does 200 cm rainfall mean?
Measuring rainfall as a depth has become an international standard mainly because it is very easy to convert depth to volume; in fact, the main conversion factor is 1 mm of rainfall = 1 Liter of water/m² (or 0.001 m³ of water/m²); thus, to answer your question, 200cm or rainfall (or 2000 mm) means that every squared …
What is the main cause of a drought?
The Short Answer: A drought is caused by drier than normal conditions that can eventually lead to water supply problems. Really hot temperatures can make a drought worse by evaporating moisture from the soil.
How are trees responsible for rain?
The trees help in bringing rain in an indirect way through the process called transpiration. Through transpiration, trees leave the extra water through the stomata on the leaf surfaces. The water evaporates into the air and adds to the moisture of the air. So the air gets saturated faster and brings rain.
How does deforestation cause to decrease rainfall?
Deforestation leads to reduced rainfall because it leads to reduction in natural recycling of moisture from the soils. This recycling takes place through vegetation and returns back in the form of rainfall. When there is heavy rainfall, the rain water does not seep down into the ground and is not absorbed by the tress.
How does deforestation reduce rainfall and lead to flood?
Deforestation means cutting down of trees or forests. We know that trees transpire and play an important role in the water cycle as it adds moisture to the air which brings rainfall. This soil will be dry and leads to lower water intake in the trees. This will cause soil erosion and will lead to floods.
How does deforestation lead to flood?
The roots in the trees are able to strengthen the soil and prevent erosion. They also absorb some of the water. When the roots are gone from trees after deforestation, there’s nothing to strengthen the soil anymore. Hence, the soil slide around and the water is able to build on the surface causing flooding.
