1. Formation of Mountains: When two continental plates collide, they push against each other. This pressure causes the land to buckle and fold, creating mountain ranges. Think of the Himalayas, formed by the collision of the Indian and Eurasian plates.
2. Volcanic Activity: When plates move apart (divergent boundaries), magma from the Earth's mantle rises to the surface, creating new crust and volcanic activity. This is seen in places like the mid-Atlantic ridge, where new ocean floor is constantly being formed.
