The Rock Cycle follows a series of steps that may simplistically be considered as :- Plutonic rocks either erupting or emerging; followed by a mountain buildingprocess; followed by a surface weathering process which produces sediments that eventually find their way to the abyssal deeps of the ocean floor.
These sediments may be consumed by subduction zones at some plate boundaries, and the sediments become deeply buried and heated. The high temperatures and pressure cause Metamorphic processes to proceed, thus making new rock minerals from the sedimentary mix. These can be investigated to determine the conditions at which these new minerals were formed.
Some of these metamorphic rocks are borne directly to the surface again as new mountain ranges, for these sedimentary rocks are lighter than plutonic ones are. Otherwise, the descending rocks will be eventually absorbed into the magma. To begin the cycle over again.
Because of the sedimentary rocks being lighter than the magmatic ones, they 'float' on the magma, forming long lasting continental plates. Some of the older ones date to about 4 billion years old.
the rock cycle starts with magma
There is realy no start, but i gusse you could say that magma and lava could be the start.
the five basic substances in the rock cycle are sediments magma igneous rock metamorphism
is soil part of rock cycle
The formation of intrusive igneous and metamorphic rocks.
Magma
the rock cycle starts with magma
Melting is the process in the rock cycle that causes magma to form.
Heat from the earth's core, via the magma drives the tectonic part of the rock cycle. This heat is derived mainly from radioactive fission of the heavy elements in the Core.Gravity drives much of the weathering part of the rock cycle. Via evaporation of water, and rain and rivers, and glaciation.Some solar radiation also energizes part of the weathering part of the rock cycle.

Igneous rock
Cooling in the rock cycle means when the rock for example: Igneous rock is transforming it needs to cool when its first magma

The formation of intrusive igneous and metamorphic rocks.
A rock cycle starts off as magma. Then as the magma cools, crystals form, and eventually the magma solidify into igneous rocks. The process breaks down into sedimentary rocks. The processes change a pre-existing igneous or sedimentary rock into a new rock called metamorphic rocks, then it melts into magma and the process starts all over.
In the Rock Cycle : The Rocks are- Sedimentary Rocks, Igneous and Metamorphic Rocks. The Intermediate Materials are- Sediments and Magma
