Rock Cycle and Earth
Rock Cycle and Earth Layers
| Question | Answer |
|---|---|
| Crust + Top of Mantle | Lithosphere |
| Thinnest layer of the Earth | Crust |
| Largest layer of Earth; made of magma | Mantle |
| Layer of Earth made of liquid metals (iron and nickel) | Outer Core |
| Layer of Earth made of solid metals (iron and nickel) | Inner Core |
| Layer of Earth that is most dense | Inner Core |
| Coolest layer of the Earth | Crust |
| Hottest layer of the Earth | Inner Core |
| Layer of the Earth that moves in convection currents | Mantle |
| Type of rock made from the cooling of magma or lava. | Igneous |
| Type of rock that means "FIRE." | Igneous |
| Igneous rocks that are formed outside a volcano | Extrusive |
| Igneous rocks that are formed inside a volcano | Intrusive |
| Crystal size formed extrusively | Small Crystals |
| Crystal size formed intrusively | Large Crystals |
| Most abundant igneous rock that makes up the Earth's surface | Basalt |
| Type of rock that is made up of several layers of sediment that gets compacted and cemented together. | Sedimentary |
| Process where sediment is "glued" together to form a rock | Cementation |
| Process where sediments are pressed together | Compaction |
| Breaking up of larger rocks into smaller bits (typically by wind, rain, plant growth, freezing, etc.) | Weathering |
| Process where sediment is carried away and deposited into lower areas, like water | Erosion |
| Rock type where rocks are changed over time due to heat and pressure | Metamorphic |
| Rocks that have a pattern of layers, stripes, bands, etc. | Foliated |
| Melted rock | Magma |
| Magma that has reached the surface of the Earth | Lava |
| Volcano that erupted in the state of Washington in May, 1980 | Mount St. Helens |
| Process where magma or lava cools and hardens into new rock | crystallization |
| Small crystals form quickly or slowly? | Quickly |
| Large crystals form quickly or slowly? | Slowly |
