Answer:
(i) The rainforests are depleting because of the developmental activities that are going on at fast speed. The biologically diverse rainforests are being destroyed day by day. It is estimated that a large area of the rainforest has been disappearing annually in the Amazon basin. As a result the topsoil is washed away when the rains fall and the lush green forest turns into a barren landscape.

water. The Ganga-Brahmaputra plains fulfil this condition because they receive high rainfall.
