How do rocks change from one type to another in the rock cycle?

The rock cycle is the natural process in which rocks transform from one rock type into another rock type over time, a type of natural recycling.

Igneous rocks, which are formed from magma cooling underground, or lava above ground are formed from previous igneous, metamorphic, or sedimentary rocks which have become melted, usually as a result of plate collision and subduction.------->

When these igneous rocks are exposed to weathering and erosion, they break down into smaller particles that are transported by wind and water to a place of deposition, where they can form into sedimentary rock strata, through a process of lithification, where excess water is squeezed out by overburden pressures and the particles are cemented together by various minerals precipitating out of solution. Igneous and metamorphic rocks can both be turned into sedimentary rocks in this way.------->

Igneous and sedimentary rocks can also be changed by heat and/or pressure into metamorphic rocks, by transforming their existing mineral structures into new minerals or realigning the existing minerals. There are different degrees of metamorphism, so even an existing metamorphic rock can become a different metamorphic rock. -------->

If these metamorphic rocks are melted, then solidify, they become igneous rocks, and the cycle starts all over again.

The rock cycle is largely driven by lithospheric plate movements which cause subduction and uplift, also by climatic conditions and the associated erosional elements.
ignious forms right from the lava, while sedimentary forms from different things even from organic particles and metamorphic format from ignious and sedimentary and changes by the extreme pressure and force between it and other colliding influences, you can tell these rocks apart very easily if you know how they are formed.
Lava and Magma are liquified rock and are made from intense heat and pressure and when they are cooled at different factors (temrature/how quickly/pressure).

They form different types of rocks and these rocks get weatherd and recycled over large peroids of time.
In nature, there are 3 types of rocks: metamorphic, igneous, and sedimentary. Metamorphic rocks form when heat and/or pressure are applied to another rock. An igneous rock is a rock that is formed by cooling magma. Finally, a sedimentary rock is formed when other rocks are weathered down by rocks and water and the particles that come off them as a result of this are compacted and cemented together to form a new rock. A mineral can form in two different ways: it can crystallize from cooling magma, or it can crystallize after a solution that it was dissolved in evaporates.
