MVMS 6 Science Q2
| Question | Answer |
|---|---|
| Three types of rocks | Igneous, sedimentary, and metamorphic. |
| Igneous rocks | *Formed by cooled and hardened magma from erupting volcanoes. *Crystal size is determined by cooling time. |
| Sedimentary rocks | *Formed by sediments cementing (gluing) and compacting (pressing) together. *Relative age can be determined by fossils. *Deposition- where rocks are dropped in a new location. |
| Metamorphic rocks | *Formed by heat and pressure. * Texture is broken into 2 groups |
| Fossil | *The preserved remains of an ancient organism. *Found in sedimentary rocks. *The deeper it is the older it is. |
| Plate Movement | *Move due to convection currents in the mantle. *Can produce earthquakes, volcanoes, faults, and mountains. |
| Plate Boundaries | *convergent boundary – plates collide (move together) *divergent boundary – plates move apart. *transform fault – plate’s slide by each other. |
| Ring of Fire | *Found along plate boundaries in the Pacific Ocean. |
| Crust | *Solid outer layer of Earth that is broken into plates. *Formed due to seafloor spreading. |
| Mantle | *Largest layer of the Earth. *Between the crust and the core. *Hot, both solid and a liquid |
| Core | *Very dense. * Hottest layer. *Metal composition. *Inner layer of Earth |
| Layers | *Temperature and pressure increase with depth. *Crust is solid with softer material in the mantle. |
