The layer of earth we walk upon in the:

• crust

• mantle

• core

• inner core

The layer of the earth where plates move apart is called:

• divergent plate boundaries

• convergent plate boundaries

• sub-ducting plate boundaries

• transform plate boundaries

Which of these events breaks down rocks into smaller pieces?

• Deposition

• Weathering

• Erosion

How are weathering and erosion the same?

• Both move sediment from one place to another.

• Both leave sediment in new places.

• Both change Earth's surface.

• Both leave sediment in new places.
