Great for geology students, these flash cards discuss the composition of the Earth's layers.
There are 12 flash cards in this set (2 pages to print.)
1. Print out the cards.
2. Cut along the dashed lines.
3. Fold along the solid lines.
Sample flash cards in this set:
|Metamorphic Rock||Rock deep within Earth's crust that has been exposed to extreme heat and pressure causing changes to its appearance, structure, and composition|
|Igneous Rock||Rock formed when heated magma or lava cools and hardens|
|Sedimentary Rock||Rock formed when sediments deposited in layers, compact, and cement together under pressure over long periods of time|
|Compaction||A process whereby sediments pack, crush, and settle under the action of gravity and pressure from overlying layers|
|Cementation||A process whereby compacted sediments bind and stick together and turn into rock|
|Plasticity||The condition of material in the asthenosphere, existing in a solid state yet having the ability to flow without being a liquid|
|Inner Core||The sphere of solid nickel and iron at the center of Earth; surrounded by the liquid outer core|
|Outer Core||The outer shell of Earth's core; surrounds the inner core and is made of liquid nickel and iron|
|Mantle||The solid layer of Earth between the crust and the core; made of dense silicates|
|Crust||The thin solid outermost layer of Earth;made of less dense silicates and is continental (landmasses) or oceanic (ocean bottoms)|
|Lithosphere||The cool, rigid, outermost layer of Earth consists of the crust and the uppermost part of the mantle; pieces of this layer are called lithospheric plates|
|Asthenosphere||The solid layer with plasticity in the upper mantle that is located just below the lithosphere; lithospheric plates "float" and move on this layer|
