What is the role of the biosphere and the lithosphere in the water cycle?

Answer 1

The biosphere is important to the hydrological cycle because without it, we would have no trees on earth. This is because the biosphere is 100m above ground and 3m below ground, that contains most living things on Earth. Without trees, precipitation would not be intercepted by the trees. Therefore the rainwater would fall straight to the ground. When it hits the ground, little or no infiltration would happen because the soil, which has been exposed to rain and sun, would be damaged or washed away in the rain. If the water can not be infiltrated, there is a higher flood risk to many people throughout the world.

The lithosphere is important to the hydrological cycle because without the lithosphere there would be no groundwater flow. This is because the lithosphere is the rocky layer of the Earth and groundwater flow goes through the rocks. There also wouldn't be any groundwater stores, as these are stores of water contained beneath the surface as a reserve. Without this, there would be fewer places to store all the water.

Answer 2

The biosphere is important to the hydrological cycle because without the trees the precipitation won't be met with any interception and therefore will go straight to the ground where little or no infiltration will happen because the land has been disturbed. this means that the water will get back to the river more quickly and therefore will cause flooding.

The lithosphere is important to the hydrological cycle because without it infiltration won't happen in the earths crust and therefore will cause surface storage and then surface runoff which will then cause flooding in the river because the water will get back faster than going all the way underground to the water table and then going into the river.

Hope this help.
