No it does not. It depends on what it starts at and what happens to it.
Magma always flows.
Water flow
Absolutely! Simply put, the wind is always blowing, the water is always flowing, therefore sedimentary processes are always occurring (wow that was a cool rhyme I just made up). Likewise, the magma within the Earth is always hot, which is always melting material, creating igneous rocks. From a metamorphic standpoint, there will always be areas with high heat and temperature, therefore there will always be metamorphic rocks. If any of these processes stopped, we'd have real problems.
This statement is incorrect because igneous rock can also transform into metamorphic rock through heat and pressure without going through the sedimentary rock stage. The rock cycle is a continuous process, and rocks can change directly from one type to another, depending on the conditions they are exposed to.
The type of rock that likely formed first to initiate the rock cycle is igneous rock.
The Rock Cycle
Always.
Flowing rock goes in a cycle that flows from the heat to the hot core but the water is more resistance and doesn't flow like the rock cycle.
Magma always flows.
Underground springs typically flow in the direction of least resistance, following natural slopes and geologic structures like faults and fractures. The flow can be influenced by factors such as topography, rock porosity, and water pressure.
Because nature is always in motion, and the very slow process of the rock cycle never truly grinds to a halt. Therefore, it is a cycle - the seeming end is but only the beginning.
No, the rock cycle does not have to start from the sedimentary rock
The lava is melted rock called magma when it is underground, then it is exposed and is then called lava. The volcano erupts, and it hardens into igneous rock. If the igneous rock heats up again, it is lava once more!
The rock cycle and water cycle both are natural.
It is called the Rock Cycle.
Water flow
there is no beginning or end of the rock cycle
