Study Notes
Rock Types
- Rocks are classified into three main types: igneous, sedimentary, and metamorphic.
Igneous Rocks
- Formed when magma or lava cools.
Sedimentary Rocks
- Formed by weathering and erosion of existing rocks.
- Weathering breaks rocks into fragments called sediments.
- Sediments are transported by rivers, ice, and wind.
- Sediments are deposited in seas or lakes, often layered with other sediments or fossils.
- Fossils are remains of sea creatures.
- Over time, the sediments compact and cement together forming sedimentary rock.
Metamorphic Rocks
- Formed when igneous and sedimentary rocks are altered by heat and pressure.
- Heat from contact with molten magma and pressure from folding can change these rocks.
