Question

distinguish between ÷ block mountain fold mountain primary and secondary waves volcanoes and earthquake​

Answer 1

Answer:

Block mountains are formed due to faulting which is caused when the horizontal movements within the earth's crust move away from each other. Fold mountains are formed due to folding which occurs when the horizontal movements within the earth's crust move towards each other.

The P-wave (primary or pressure wave) is a pulse of energy that travels quickly through the earth and through liquids. ... The S-wave (secondary or shear wave) follows more slowly, with a swaying, rolling motion that shakes the ground back and forth perpendicular to the direction of the wave.
