The rock cycle involves a series of processes that transform rocks from one type to another over geological time. The three major transitions in the rock cycle are:
1. **Igneous Rock Formation**: This transition involves the cooling and solidification of molten rock (magma or lava) to form igneous rocks. When magma cools slowly underground, it forms intrusive igneous rocks, while rapid cooling at the surface results in extrusive igneous rocks.
2. **Metamorphic Rock Formation**: This transition occurs when existing rocks (igneous, sedimentary, or other metamorphic rocks) are subjected to high temperatures and pressures, causing physical and chemical changes without melting. The resulting rocks are known as metamorphic rocks.
3. **Sedimentary Rock Formation**: This transition involves the weathering and erosion of pre-existing rocks, leading to the deposition of sediments. Over time, these sediments are compacted and cemented together, forming sedimentary rocks.
These transitions illustrate the dynamic processes that constantly recycle materials within the Earth’s crust, contributing to the continuous evolution of rock types.
