Study Notes
Rock Formation and Transformation
- Lava cools and hardens to form igneous rock after volcanic eruptions.
- ROCK WEATHERING processes lead to the creation of soil from rocks.
Sediments and sedimentary rock
- Sediments, carried by the Mississippi River, are compacted and cemented over millions of years to form sedimentary rocks.
- Transportation of sediments occurs through natural elements; wind carries soil, while rain washes it into rivers.
- When sediments lithify, they transform into sedimentary rock.
Types of Rocks
- Various rock types include:
- Metamorphic Rock: Formed under heat and pressure from existing rocks.
- Sedimentary Rock: Created from compressed and cemented sediments.
- Intrusive Igneous Rock: Forms when magma cools beneath the Earth's surface.
- Extrusive Igneous Rock: Forms when magma cools on the Earth’s surface.
Magma Characteristics
- Magma, found beneath the Earth's crust, has temperatures around 1000 degrees Celsius.
- Deep underground melting of rocks results in the creation of magma.
Rock Cycle
- The rock cycle involves continuous transformation and includes various processes:
- Transition from magma to intrusive igneous rock.
- Formation of soil from broken-down rocks.
- Sediments eventually lead to sedimentary rocks through compaction and cementation.
Rock Cycles Examples
- Three defined rock cycles include:
- Cycle 1: Soil → Sediment → Sedimentary Rock → Soil
- Cycle 2: Magma → Intrusive Igneous Rock → Magma
- Cycle 3: Extrusive Igneous Rock → Soil → Sediment → Sedimentary Rock → Metamorphic Rock → Magma → Extrusive Igneous Rock
Transformations in the Rock Cycle
- Key transformations include:
- Intrusive Igneous Rock to Sedimentary Rock: Involves exposure, weathering, deposition, compaction, and cementation.
- Metamorphic Rock to Sediment: Occurs via exposure, weathering, erosion, and deposition.
- Sediment to Sedimentary Rock: Requires compaction and cementation.
- Sedimentary Rock to Sediment: Involves exposure, weathering, and deposition.
