Explanation / Answer
9. B. Hotspot areas formed above the mantle separately, continuous intrusion of mantle material causing it to raise the temperature causing volcanic activity,these hot spots remain at particular position and the plate move over it causing the lithosphere region which is over the hot spot to form volcano later when the plate moves over it causing volcano to become extinct, this hot spot form chain of volcanoes and the examples are yellowstone and hawaii.
23.C. Inorder to form a lake there must be a sufficient inflow of water to keep the basin filled and a landscape must have a basin with restricted outlet
26.C. Marshes are wetlands without trees and have small shrubs to grass, whereas Swamps are wetlands with trees, so the answer is wetlands are the areas with saturated water.
27. B. Identifying and analyzing distributions of species over a long period of geological time is called biogeography.
