erosion
A sedimentary rock can be re-formed through the process of lithification, where loose sediment is compacted and cemented together to create a solid rock. This can occur through pressure from overlaying sediment layers and the precipitation of minerals in the pore spaces between sediment grains. Over time, these processes transform loose sediment into a cohesive sedimentary rock.
Sandstone can be transformed into sediment through weathering processes like erosion, transportation, and deposition, without going through metamorphic or igneous stages. Weathering breaks down the sandstone into smaller particles, which are then transported by wind, water, or ice and deposited in a new location as sediment. This sediment can then be compacted and cemented together to form new sedimentary rock.
False. The rock may undergo further metamorphism, or it may melt and re-solidify into igneous rock, or it may be broken down into sediment at the surface and later become sedimentary rock.
False A+
What processes must occur to produce an igneous rock
Melting and solidification are the processes that must occur for a rock to change into igneous rock.
The process that must occur to change any rock to igneous rock is melting.
Particles that settle out of water are usually referred to as sediment or suspended solids. These particles can include clay, silt, sand, and organic matter. settling can occur due to gravity as the particles become heavier than the surrounding water.
Igneous rock forms from the solidification of magma and lava; this can occur at or below the surface.
In the rock cycle, rocks undergo continuous transformation through processes like weathering, erosion, deposition, and metamorphism. Igneous rocks can be weathered and eroded into sediment, which can then be compacted and cemented to form sedimentary rocks. These rocks can be subjected to heat and pressure to become metamorphic rocks, which can then melt and cool to form new igneous rocks, completing the cycle.
A xenocryst is a crystal which does not occur in a specific igneous rock.
Volcanic eruption.
