15.*Three plates are:
Convergent plate boundariesThese are the margins where plates moves towards each other and the part of the crust is subducted into the asthenosphere .Thus, it leads to the destruction of the crust.
Divergent plate boundariesThese are the boundaries were plate moves away from each other.It leads to the eruption of the magma from the aethenosphere and its solidification.Thus new crust is generated.
Transform Boundaries:These are regions where plates slides pass each other without colliding.
16*Peninsular rivers :It is seasonal but Himalayan river are perennial.
