Most Upvoted Answer
Explain rock cycle?
The rock cycle is a continuous process that describes how rocks are formed, transformed, and destroyed over time. It involves a series of geological processes that occur naturally and are driven by various factors such as temperature, pressure, erosion, and volcanic activity. The rock cycle can be divided into three major stages:

1. Formation
- Rocks are formed through different processes such as cooling and solidification of magma or lava, deposition of sediment, and compression of existing rocks.
- Igneous rocks: These rocks are formed from the cooling and solidification of magma or lava. They can be either intrusive (formed below the earth's surface) or extrusive (formed on the earth's surface).
- Sedimentary rocks: These rocks are formed from the deposition and compaction of sediment such as sand, mud, and other particles.
- Metamorphic rocks: These rocks are formed from the transformation of existing rocks due to changes in temperature, pressure, or chemical composition.

2. Transformation
- Rocks can undergo various transformations due to geological processes such as weathering, erosion, and tectonic movements.
- Weathering: This process involves the breakdown of rocks into smaller pieces due to exposure to elements such as wind, water, and ice.
- Erosion: This process involves the transport of rocks and sediments by natural agents such as water, wind, and ice.
- Tectonic movements: These are movements of the earth's crust that can cause rocks to be deformed, folded, or uplifted.

3. Destruction
- Rocks can be destroyed through various processes such as weathering, erosion, and volcanic activity.
- Volcanic activity: This involves the eruption of magma and lava from the earth's surface, which can lead to the destruction of existing rocks and the formation of new ones.
- Weathering and erosion: These processes can cause rocks to break down into smaller pieces and eventually be transported away by natural agents such as water, wind, and ice.

In conclusion, the rock cycle is a continuous process that involves the formation, transformation, and destruction of rocks over time. It is driven by various geological processes and can lead to the formation of different types of rocks depending on the conditions and factors involved.

Explain rock cycle?
The rock cycle is a process in which rocks are continuously trabsformed between the three rock types igneous, sedimentary , metamorphic if the sediments are burid under further layer of sediments they can become lithified to produce a sedimentary rock magma is produce when rocks are melted
