|
Mantle |
Less dense, elastic rock, geothermal energy |
|
|
Lithosphere |
Uppermost mantle and crust, solid part of earth, includes rocks, sediment, and soil at surface, extends many miles. |
|
|
Lithosphere |
Broken into plates, brittle, heat, pressure, and has convection because it's broken into plates |
|
|
Divergent plate boundaries |
Mid ocean ridge. Magma surging upward to the surface divides the plates and pushes them apart. Creates new crust as it cools. |
|
|
Transform plate boundary |
Two plates meet. Slip and grind along side eachother. Friction=earthquakes |
|
|
Convergent boundaries |
Plates collide |
|
|
Subduction |
One plate of crust may slide beneath another. |
|
|
Magma |
Erupts through surface in volcanoes. Molten, liquid state of rock. |
|
|
Lava |
Magma released from the lithosphere |
|
|
Igneous rock |
forms when molten rock material cools above (extrusive) or below (intrusive) and the earth's surface. |
|
|
Sedimentary rock |
Forms when sediment is weathered from preexisting rocks and deposited in a body of surface of water where buried and compact. Sandstone, limestone, lignite and bituminous coal |
|
|
Metamorphic rock |
Formed when a preexisting rock is subjected to high Temps and or pressures causing it to melt. Anthracite coal, marble, and slate. |
|
|
ore |
Economically exploitable deposit |
