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.)
To use:
1. Print out the cards.
2. Cut along the dashed lines.
3. Fold along the solid lines.
Sample flash cards in this set:
| Questions | Answers |
|---|---|
| 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 |
