Rock Definitions
What is igneous rock?
Formed from melted rock deep underground.
What is weathering?
The process of breaking down rocks into sediment by wind, ice, or plants.
Moving Apart boundaries are...
...Divergent Boundaries, and they form mid-ocean rifts.
What is the Crust's approximate temperature and state of matter?
Solid; 50˚C-1000˚C.
What is metamorphic rock?
Pre-existing rock buried deep underground that is modernly altered with heat and pressure.
What is erosion?
The movement of sediment to a new location and/or wearing down into different shapes.
Sliding Past boundaries are...
Transform Boundaries, and they form faults and earthquakes.
What is the Mantle's approximate temperature and state of matter?
Semi-solid; 100˚C-3700˚C.
What is sedimentary rock?
Formed by layers of dirt, rock, and dust compacting deep underground - over time, it forms rock.
What is deposition?
The process where sediment is dropped or settled into a new location, commonly in layers.
Colliding Together boundaries are...
Convergent Boundaries, and they form mountains, volcanoes, and trenches.
What is the Outer Core's approximate temperature and state of matter?
Liquid; 4000˚C-5000˚C.
What is compactation/cementation?
What is the Inner Core's approximate temperature and state of matter?
Solid; 5000˚C-6000˚C.
