Joe Stafford, Tiernan Brunner, Brighton Lorber

Shaping Earth Weathering

Chemical Mechanical

Erosion Ex: Mountains, plateaus, valleys, Grand

canyons, deltas.

Rebuilding Earth Deposition

Carried by water, ice, or wind Ex: Himalayas and Plains

Plains created by sediment

plates – huge blocks of earth ( continents and water)

Magma – partly melted rock, acts like conveyor belt Motion of plates = Earthquakes and Volcanoes
