FORCES ON EARTH’S STRUCTURES, INSIDE EARTH
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
Forces Inside Earth Theory of Plate Tectonics
plates – huge blocks of earth ( continents and water)
Magma – partly melted rock, acts like conveyor belt Motion of plates = Earthquakes and Volcanoes
Earthquakes and VOLCANOES
Earthquakes caused by seams in earth called Faults Only some cause harm to people
Earthquakes caused by seams in earth called Faults
