The rock cycle can begin with the formation of magma from the melting of existing rocks in the Earth's mantle. It ends when rocks are weathered and eroded into sediment, which can then be compacted and cemented together to form new sedimentary rocks, completing the cycle.
The process by which an igneous rock changes to a sedimentary rock in the rock cycle begins with weathering and erosion of the igneous rock, breaking it down into sediments. These sediments are then transported and deposited, where they are compacted and cemented together to form a sedimentary rock over time.
The type of rock that likely formed first to initiate the rock cycle is igneous rock.
The rock cycle is a continuous process that involves the formation, transformation, and reformation of rocks through various geological processes such as weathering, erosion, and heat/pressure.
The rock cycle is a continuous process with no specific end point. Rocks can be transformed into different types through processes such as weathering, melting, and re-crystallization. This cycle continues as long as Earth's geological processes are active.
The stage in the rock cycle where every type of rock can go through directly is the metamorphic stage. This is where rocks are subjected to intense heat and pressure, causing them to change into new types of rocks without needing to go through the other stages of the rock cycle.
