Answer is Right!
Answer is Wrong!
The correct answer is C. rock cycle.
The rock cycle is a model that describes the processes that form, transform, and destroy rocks. It is a closed system, meaning that the total amount of rock on Earth does not change. However, the type of rock that exists at any given time can change as rocks are recycled through the cycle.
The rock cycle is driven by four main processes:
- Weathering: This is the process by which rocks are broken down into smaller pieces by the action of wind, water, ice, and other natural forces.
- Erosion: This is the process by which weathered rock material is transported from one place to another.
- Deposition: This is the process by which eroded rock material is deposited in another location.
- Lithification: This is the process by which sediment is compacted and cemented together to form rock.
The rock cycle can be divided into three main types of rocks: igneous, sedimentary, and metamorphic.
- Igneous rocks are formed when magma or lava cools and solidifies. Magma is molten rock that exists beneath the Earth’s surface. Lava is magma that has reached the Earth’s surface.
- Sedimentary rocks are formed when sediment is compacted and cemented together. Sediment is material that has been transported from one place to another by weathering and erosion.
- Metamorphic rocks are formed when existing rocks are subjected to heat and pressure. This can happen when rocks are buried deep beneath the Earth’s surface or when they are involved in mountain building.
The rock cycle is a dynamic process that is constantly in motion. Rocks are constantly being recycled through the cycle, and the type of rock that exists at any given time can change.
