What is the difference between a valley glacier and continental glacier?
Valley- long and narrow, found high in mountains
Continental- large, spread out over wide areas
All the __________ is picked up by wind eventually falls to the ground
sediment
List the five forces that cause erosion
gravity, running water, glaciers, waves and wind
What is the roof of a cave and floor of a cave called (two separate names)
stalagmite & stalactite
What is the difference between kinetic and potential energy?
Kinetic- is the energy an object as due to its motion
Potential- energy that is stored for a later use
When does a glacier deposit the sediment it is carrying?
When the glacier melts
