Science Final
| Question | Answer |
|---|---|
| Lithification | Process through which sediments turn into rock. |
| Fiolation | Results when pressure causes flat minerals to line up, giving the rock a layered appearance. |
| Erosion | happens when running water, wind, waves, or glaciers pick up rocks from Earth’s surface and move them around. |
| Weathering | Process that breaks rocks into fragments and sediments. |
| Mechanical Weathering | Breaks down rocks without changing their chemical composition. |
| Chemical Weathering | Occurs when water, air, or other substances react with the minerals in rocks, soil, and building materials to change their chemical composition. |
| Metamorphism | Occurs when subjected to high temperature and pressure |
| Crystallization | When magma or lava cools down and turns from a liquid to a solid. |
| Sedimentary Rocks | Formed from pre-existing rocks or pieces of once-living organisms. They are also formed mainly by weathering. |
| Metamorphic Rocks | Formed from other rocks that are changed because of heat or pressure. These rocks have smaller mineral grains that are flattened or aligned. |
| Intrusive Igneous Rocks | Forms when trapped magma cools (inside). |
| Extrusive Igneous Rocks | These are the rocks that form at erupting volcanoes and oozing fissures. (outside) |
| Rock Cycle | The series of processes that continually change one rock into another type of rock. |
| Which is true of the size of crystals in igneous rock? | Igneous rock that forms above Earth's surface has smaller crystals than igneous rock that forms below Earth's surface. |
| What does the texture of an igneous rock refer to? | its grain size and arrangement |
| Which of the following is a foliated metamorphic rock? | slate |
| What type of rock is marble? | metamorphic |
| Where does the rock cycle occur? | both on top of and below the Earth's surface |
| Within the rock cycle, which transition does not occur in one step? | magma to sedimentary rock |
| What do the terms "extrusive" and "intrusive" describe? | the location where igneous rock is formed |
| Which process moves large amounts of rock up to Earth's surface and higher elevations? | uplift |
| Where are Earth's oldest rocks usually found? | in the middle of tectonic plates |
