Question

WHat process is involed in the formation in rocks

Answer 1

Do you mean "What processes are involved in the formation of rocks?" If so, here is a brief summary.

Rocks form through processes in the rock cycle. The main processes are:

- Igneous formation: cooling and solidification (crystallization) of magma or lava. Example: granite (slow cooling underground), basalt (fast cooling at the surface).
- Sedimentary formation: weathering and erosion break existing rock into particles, transport and deposition of those particles, then compaction and cementation (lithification). Chemical precipitation and biological accumulation (e.g., shells forming limestone) also make sedimentary rocks. Example: sandstone, shale, limestone.
- Metamorphic formation: alteration of existing rocks by heat, pressure, and chemically active fluids without melting, causing recrystallization and new textures/minerals. Example: shale → slate → schist; limestone → marble.
- Melting: any rock can melt to form magma, completing the cycle.

Other important processes: chemical precipitation, hydrothermal activity, diagenesis, uplift and erosion driven by plate tectonics and surface processes.

If you want, I can explain any one process in more detail or show a simple diagram of the rock cycle.
