The lithosphere a combination of the crust and the uppermost brittle layer of the mantle is divided into tectonic plates, including the seven major tectonic plates.
Answer:
The top soil particles are finest and porous so that it allows more water to retain in it. The top soil is darker in colour due to the presence of humus which makes it fertile and best for plant growth.
I think it's because there are no plants to feed anymore, water isn't being soaked up so the extra water causes flooding.
