Across
- 1. Rocks are classified, in part, based on their silica content.
- 7. The process where the moving sediment stops and comes to rest.
- 10. The process where agents like water, wind, or glaciers carry the loose sediment away.
- 11. When magma comes out of a volcano, it is called
- 12. Igneous rock formed from lava, above the surface of the earth.
- 13. Igneous rock formed from magma, inside the earth.
- 14. The gradual degradation of a rock due to elemental factors such as wind and rain, which chip away at pieces of a rock over time, and changes in temperature.
Down
- 2. Rocks that usually occurs when the original rock was composed mainly of one mineral (like quartz or calcite) or when the rock formed under low-pressure conditions where minerals did not get squeezed into parallel layers.
- 3. This happens over a large area, deep within the Earth's crust, usually where tectonic plates are colliding.
- 4. Rocks that form only on the Earth's surface.
- 5. Rocks form when minerals crystallize directly from water
- 6. Metamorphic rock that forms from pressure squeezes the platy (flat) and elongate (long) mineral grains, causing them to line up in parallel, flat layers.
- 8. This occurs when hot magma (molten rock) rises into the shallow crust and heats the cooler surrounding rock, changing it.
- 9. Made from fragments (pieces) of older, weathered rocks.
