A landslide quickly erodes sediment on a steep hill. When the landslide reaches the bottom of the hill, it slows down and finally comes to rest. The sediments it leaves are called __________________.

• weathering

• sediment

• deposition

• epicenter

Why do earthquakes occur along faults?

• Rocks along a fault are stable.

• Rocks along a fault are easily eroded

• Rocks along a fault are under pressure.

• Rocks along a fault are easily weathered.

Volcanoes and earthquakes are two effects of plate tectonics. What does the theory of plate tectonics state?

• Earth's mantle is solid.

• Earth's crust is divided into parts that move.

• Earth's inner core causes changes in the crust.

• Earth's outer core is liquid, and its inner core is solid.
