Explanation:
According to the rock cycle, all of the transitions given are possible with several unlimited steps.
The rock cycle shows how the different rock types are transformed from one form to another.
In the rock cycle the major rock types are taken into consideration. These rock types are Igneous, sedimentary and metamorphic.
- An intrusive igneous rock becomes a sedimentary rock.
Based on the rock cycle, an intrusive rock can become a sedimentary rock. This is igneous to sedimentary rock conversion. Here, the intrusive rock is brought during a terrain change to the surface. Weathering, erosion, transportation and deposition combines to produce sediments and take them to their basin of deposition where they form sedimentary rocks.
- A sedimentary rock becomes soil.
By weathering, a sedimentary rock can be come a soil. Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soil.
- A metamorphic rock becomes an extrusive igneous rock.
When metamorphic rocks are subjected to intense heat and pressure, they reach their melting point.
As they melt, they produce magma which can be brought to the surface to form extrusive volcanic rocks.
