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

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

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

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

 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)

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

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

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

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

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