1 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 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 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.

4 4. The point on the earth´s surface that is above where the earthquake begins
Epicenter

5 4a. The name of the plates under the surface of the earth
tectonic plates

6 4b. The place where 2 tectonic plates meet
Fault line

7 State if the example shows erosion or weathering.
