Term | Definition |
---|---|
Geology | Study of the dynamic (moving) processes on/in the Earth's surface & interior |
Core | Center of Earth made of hot molten rock called magma/lava |
Mantle | Thickest zone Earth, made of plastic rock (lower portion) and hot solid rock (outer portion) |
Crust | Outside zone |
Lithosphere | Outer portion of mantle and crust layer, make up tectonic plates (7 plates) |
Convection Cells | Hot molten rock that loops from the core to the outer most portion of mantel |
Tectonic Plate | 7 total plates, 50 miles thick, moving at about the speed of finger nail growth. In an Earthquake one plate pushes against another plate and slips below another. |
Fault | Surface cracks along/at the plate boundaries. Most famous is the San Andreas fault in CA. |
Seismic | Release of high activity/energy release along the fault line |
San Andreas Fault | Most famous fault line |
Trench | When ocean plates collide |
Mountain/hills | When Continental plates collide |
Tsunami | Giant sea swells as the result of generation of earthquakes and energy release. |
Environmental Effects on the Earth's surface | 1. Weathering to produce soil (physical, chemical, and biological process that break down rocks to release minerals and litter in the form of leaves, and twigs. 2. Erosion from wind and water depletes in one area, and redeposits in another 3. Glaciers- |
Continental glaciers | Formed the great lakes |
Weathering to produce soil | (physical, chemical, and biological process that brea down rocks to release minerals and litter in the form of leaves, and twigs. |
Erosion from wind and water | Depletes in one area, and redeposits in another |
Glaciers | Large sheets of flowing ice |
