How does igneous rock become sediment?

Igneous rocks can become sedimentary rocks by weathering, erosion, deposition, and compaction. Igneous rock at Earth's surface breaks down into sediments by weathering. Erosion carries the sediments and deposits them in layers. Over time, these layers become buried and compacted to form sedimentary rock.

What is the difference between sedimentary and igneous rocks?

The three main rock types are igneous, sedimentary, and metamorphic. Igneous rocks form from cooling magma. The chemical composition of the magma and the rate at which it cools determine what rock forms as the minerals cool and crystallize. Sedimentary rocks form by the compaction and cementing together of sediments, broken pieces of rock-like gravel, sand, silt, or clay. Those sediments can be formed from the weathering and erosion of preexisting rocks. Sedimentary rocks also include chemical precipitates, the solid materials left behind after a liquid evaporates. Metamorphic rocks form when the minerals in an existing rock are changed by heat or pressure within the Earth.

Can an igneous rock become an igneous rock? Can sedimentary rock become a sedimentary rock? Can metamorphic rock become a metamorphic rock?

In the rock cycle, rocks can undergo changes that lead to the formation of the same general type of rock. Sedimentary rock layers can be weathered, and the resulting sediments can be deposited and buried to form new sedimentary rock. Metamorphic rock exposed to heat and/or pressure can become further altered to form another type of metamorphic rock before melting completely. Igneous rock exposed to a high degree of heat and/or pressure can melt and later recrystallize to form new igneous rock.

What is the definition of uplift in the rock cycle?

Uplift in the rock cycle refers to the process where Earth's crust rises due to tectonic forces, bringing rocks from deep within the Earth to the surface. This can lead to the exposure of rocks to weathering and erosion, which are key processes in the rock cycle.

What are the two forces that drive the rock cycle on Earth?

The two main forces that drive the rock cycle on Earth are plate tectonics and the weathering, erosion, and deposition processes. Plate tectonics cause the formation, movement, and destruction of rocks on Earth's crust. Weathering, erosion, and deposition, driven by the Sun's energy, break down, move, and deposit rocks at the Earth's surface.
