Ch- physical features of India
1. what do you mean by the theory of plate tectonics? Ans Earth scientists have explained the formation of physical features with the help of some theories and one such theory is the ‘Theory of plate tectonics’ according to this theory , the crust of the earth has been formed out of seven major and some minor plates . The movement of these plates resulted in building up of stresses within the plates, leading to folding, faulting and volcanic activities. 2. what are the three types of plate movement on the earth? Ans (1) coverage boundary: When some plates come towards each other, they form a coverage boundary. It may also be cold folding movements (2) Divergent boundary: when some plates move away from each other they form a divergent boundary. It is also called faulting movements. (3) Transform boundary: In the event of two plates coming together, they may either collide and crumpled or may slide under each other and formed the transform boundary. 3....
