How earthquake and volcano change the earth crust

Wind, water, and ice erode and shape the land. Volcanic activity and earthquakes alter the landscape in a dramatic and often violent manner. And on a much longer timescale, the movement of earth's plates slowly reconfigures oceans and continents. Each one of these processes plays a role in the Arctic and Antarctica.

Explanation:

Volcanoes, earthquakes,landslides, and floods can change Earth's surface very quickly. Volcanoes Temperatures are so high at the bottom of Earth's crust that rocks melt. Melted rock below Earth's surface is called magma. ... It moves to Earth's surface where the crust is weakest.
