Describe the steps of the rock cycle and relate them to weathering, erosion, plate tectonics, and mountain building.
The rock cycle involves several steps:
1. Weathering: This is the process where rocks are broken down into smaller pieces through physical or chemical means. Factors like wind, water, and temperature changes contribute to weathering.
2. Erosion: Once rocks are weathered, the smaller particles are carried away by natural forces like water, wind, or ice. This movement of materials can take them to new locations where they may eventually settle.
3. Deposition: Eroded materials are deposited in new areas, often accumulating in layers. Over time, these layers can compact and cement together to form sedimentary rocks.
4. Lithification: This is the process where sediments undergo compaction and cementation to become solid rock.
5. Metamorphism: As rocks are subjected to high pressure and temperature (often due to plate tectonics), they can transform into metamorphic rocks.
6. Melting: If rocks are subjected to extreme heat, they can melt into magma.
7. Cooling and Solidification: When magma cools, it solidifies into igneous rocks, completing the rock cycle.
Relation to Plate Tectonics and Mountain Building:
– Plate tectonics play a crucial role in the rock cycle, as the movement of Earth’s plates can cause uplift, forming mountains.
– This uplift exposes rocks to weathering and erosion.
– Subduction can lead to melting and the formation of magma
