Faultingrocks under tectonic pressure fracture unter strain (earthquake) moves up and down to create a fault or scarp, under water it may cause a tsunami
Volcanismprocess related to molten rock matter and its movements that shape earth by: a)filling in the gap left by plates moving apart b)magma cooling c)magma flowing on surface (lava) d)creates new land
GradationA.Weathering- breaking down of rock into particles ex:ice expansion of rock cliff B)Erosion-movement of weather rock from one location to another (rocks sliding down mountain) C.Deposition-the process of lying/depositing weathered rock particles in new location (BEACHES STONE RIVERBEDS)
Glaciation (movement of ice)special importance to canada, tundra regions features as a result of glaciers
