The rock cycle is a continuous process that involves the transformation of rocks from one form to another over time. The steps involved in the rock cycle are as follows:
1. Formation: Rocks are formed through various processes such as cooling and solidification of molten magma, compression and cementation of sediments, or metamorphism of existing rocks due to heat and pressure.
2. Weathering and erosion: Rocks on the Earth's surface are constantly exposed to weathering processes such as wind, water, and ice, which break them down into smaller pieces. These broken pieces, called sediments, are then transported by erosion to new locations.
3. Deposition: The sediments are deposited in layers on the Earth's surface, often in bodies of water or on land. Over time, these sediments can accumulate and become compacted and cemented together to form sedimentary rocks.
4. Burial and compaction: As more layers of sediment accumulate on top of existing rocks, the pressure from the overlying layers causes the sediments to become compacted and solidified into sedimentary rocks.
5. Heat and pressure: Over time, sedimentary rocks can be subjected to heat and pressure deep within the Earth's crust, causing them to undergo metamorphism and transform into metamorphic rocks.
6. Melting: If metamorphic rocks are subjected to extreme heat and pressure, they can melt and become molten magma. This magma can then cool and solidify to form igneous rocks.
7. Cooling and solidification: Magma that reaches the Earth's surface through volcanic activity cools and solidifies to form igneous rocks. This process can also occur underground, resulting in the formation of intrusive igneous rocks.
Overall, rocks are changed from one form to another through a combination of processes such as weathering, erosion, deposition, burial, compaction, heat, pressure, melting, cooling, and solidification. These processes are interconnected and cyclical, leading to the continuous transformation of rocks over time in the rock cycle.

Steps Involved in the Rock Cycle:
1. Weathering and Erosion:
- Rocks exposed to the elements (e.g., water, ice, wind) break down into smaller fragments (weathering).
- These fragments are then transported by various processes (erosion).
2. Sedimentation:
- Transported rock fragments accumulate in low-lying areas, such as rivers, lakes, and oceans.
- Over time, these sediments become compacted under increasing layers of materials.
3. Diagenesis:
- Sediments undergo chemical changes, such as cementation and recrystallization.
- This process converts loose sediments into solid sedimentary rocks.
4. Metamorphism:
- Sedimentary or igneous rocks are subjected to intense heat and pressure within Earth's crust.
- This causes them to recrystallize and form metamorphic rocks.
5. Melting (Igneous Formation):
- Metamorphic or sedimentary rocks can melt under extreme heat and pressure.
- The molten material (magma) rises towards the surface and cools, forming igneous rocks upon solidification.
6. Uplift and Exposure:
- Igneous or metamorphic rocks may be uplifted during geological processes, such as mountain building.
- This exposes them to weathering and erosion, starting the cycle anew.
How Rocks Change from One Form to Another:
- Sedimentary to Metamorphic: Heat and pressure alter the mineral composition and texture of sedimentary rocks.
- Sedimentary to Igneous: Sedimentary rocks melt under intense heat, forming igneous rocks.
- Igneous to Metamorphic: Igneous rocks can undergo metamorphism under high temperatures and pressures.
- Metamorphic to Igneous: Metamorphic rocks can melt, forming igneous rocks.
- Metamorphic to Sedimentary: Metamorphic rocks can weather and erode, forming sediments that can eventually become sedimentary rocks.
- Igneous to Sedimentary: Igneous rocks can weather and erode, forming sediments that can become sedimentary rocks.
