i don't remember but it starts with erosion and the last is cementation
No, the rock cycle does not have to start from the sedimentary rock
Three (3) rocks in the rock cycle are sedimentary, igneous, and metamorphic rock.
sedimentary rock
The rock cycle describes how rocks are formed, and how they change to sedimentary rock, to metamorphic rock, to magma, to igneous rock, to sediment, and back to sedimentary rock.
It must erode into sediment and then be compressed to form sedimentary rock.
Because a sedimentary rock goes through the rock cycle.
yes it erodes
Igneous rock can weather and become sedimentary rock . Metamorphic rock can be melted in a volcano and become igneous rock. Igneous rock and sedimentary rock can be heated and pressurized to form metamorphic rock.
sedimentary, igneous, and metamorphic
They all are part of the rock cycle
For most purposes there is no "beginning" to the rock cycle. Any rock can be weathered away and remade into sedimentary rock. Igneous rocks are sometimes depicted as the start of the rock cycle because the first rocks on Earth were igneous.
