2.  Lithosphere-rocky outer layer of Earth including the crust and upper mantel.  Hydrosphere-all the water on Earth.

3.  A force that slowly wears away or breaks down mountains and other features on the surface of Earth.

4.  The breaking down of rocks into smaller pieces called sediment.

5.  The movement of sediment on Earth’s surface from one place to another. ◦ Gravity ◦ Running water ◦ Glaciers ◦ Wind ◦ Ocean currents

7.  Water Erosion  The higher the slope of a stream or river, the more erosion will occur. (gradient)  The more water in a river, the more erosion will occur. (discharge)

9.  As these giant sheets of ice move, they carve into the surface of Earth, taking sediment with them.

11.  Events that build up Earth’s lithosphere and cause the land to rise.

12.  Magma from volcanoes hardens to form igneous rock and volcanic mountains. (subduction)

13.  When plates collide, the lithosphere can be folded up or down creating mountains.  Faults at transform plate boundaries can create mountains.

15.  The process by which eroded sediment is dropped off or deposited in a new area. ◦ Gravity ◦ Water ◦ Wind ◦ Glaciers ◦ Ocean currents
