1. how is sedimentary rock formed?\n2. what two things are needed to form metamorphic rock?\n3. what causes…

Brief Explanations:

1. Sedimentary rock forms when sediments (small rock - particles, minerals, and organic matter) are deposited, compacted, and cemented together over time.
2. Metamorphic rock requires heat and pressure to form. These forces cause pre - existing rocks to change in texture and mineral composition.
3. Igneous rock forms when magma (molten rock beneath the Earth's surface) or lava (molten rock on the Earth's surface) cools and solidifies.
4. A metamorphic rock can turn into sediment. Weathering and erosion break down the metamorphic rock into smaller particles, which become sediments.
5. The rock cycle shows that rocks are always changing as igneous rocks can be weathered and eroded to form sediments which become sedimentary rocks, sedimentary and igneous rocks can be transformed into metamorphic rocks under heat and pressure, and metamorphic rocks can also be weathered and eroded or melted to start the cycle again.

Answer:

1. Sediments are deposited, compacted, and cemented.
2. Heat and pressure.
3. Cooling and solidification of magma or lava.
4. Yes. Through weathering and erosion.
5. Rocks change through weathering, erosion, deposition, compaction, cementation, heat, and pressure in a continuous cycle.
