Chapter 5 Science
| Question | Answer |
|---|---|
| The layer of gases that surrounds the Earth. | atmosphere |
| A sudden movement of Earth's crust. | earthquake |
| The process through which weathered rock is moved from one place to another. | erosion |
| What causes erosion? | gravity, glaciers, running water, waves, wind |
| A deep crack in earth's crust. | fault |
| A scientist who uses rocks to learn about earth's history and structure. | geologist |
| A stationary location in Earth's mantle where magma melts through a tectonic plate. | hot spot |
| A physical feature on Earth's surface. | landform |
| Hot, melted rock that reaches Earth's surface. | lava |
| The amount of energy released by an earthquake | magnitude |
| An opening in earth's crust where lava goes through | volcano |
| Continental plates are always in motion. | continental drift |
| Scientists believe continents fit together like a jigsaw. What was the continent called? | Pangea |
| Three types of volcanos | shield, cindercone, composite |
| Thin lava that spreads. Volcano is wide and fairly flat. | shield volcano |
| Thick lava thrown high in the air. Upside down cone shape | cindercone volcano |
| made of layers - ash, cinders, hardened lava | composite volcano |
| A huge wave caused by an earthquake under the ocean | tsunami |
| Where the waves from an earthquake fist hit the surface of the earth | epicenter |
| when chemicals break down rocks | chemical weathering |
| Causes chemical weathering | acid rain |
| Breaking up of rocks, but they still stay rocks, just get smaller | physical weathering |
| First two layers of the earth | inner core and outer core |
| middle two layers of the earth | lower mantle and upper mantle |
| The part of the earth we stand on | crust |
| layer of water on the surface of the earth | hydrosphere |
| layer of air on the surface of the earth | atmosphere |
| The process by which eroded materials get dropped off in another place. | deposition |
| When water picks up and carries material | erosion |
| When erosion puts down what it was carrying | deposition |
| Where are most volcanos found | Where plates meet |
| Measures magnitude of an earthquake at any specific spot | Mercalli Scale |
| Rates earthquake with roman numerals (I to VII) | Mercalli Scale |
| Measures magnitude of the earthquake where the waves first meet the earth's crust. | Richter Scale |
| Measures earthquake with numbers (0-9) | Richter Scale |
| Types of landforms | mountain, hill, valley, plateau, desert, beach, dune, plain, canyon, cliff |
| Type of water forms | ocean, inlet, waterfall, coast, tributary, river, lake |
