Marsden's Rock Cycle

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.

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.
