1. How can a volcanic eruption change the surface of the earth? The hardened lava forms a cone-shaped landform. New rocks form from the lava once it cools down. Trees and other plants near the eruption will be destroyed.

2. How can an earthquake change the surface of the earth? More cracks form on the ground. Parts of the ground could separate. Buildings and homes are weakened because of the movement. Trees are destroyed.

3. What is the difference between “weathering” and “erosion”? Weathering is the breaking apart or changing of rocks and erosion is the movement or wearing down of rock, sand or soil.
