Answer 1

Cooling of magma associates with igneous rock. Magma below the earth undergone slow cooling to produce well defined crystals. If the magma crystallised at depth it is called as plutonic magma or at intermediate depth it is hypobayssal magma and very sallow depth termd as volcanic rock. These are the three types of igneous rock that form due to cooling of magma. These are also called primary rock.

Sediment lithification produce sedimentary rocks a sediment undergoes compaction, cementation, diagenesis and lithification to produce a unconsolidated sedimentary rock. Sediments are derived from a source rock and the source rock undergoes weathering, erosion and transportation by a transporting agency like River, glacier, and wind etc.

High temperatures high pressure hydrothermal fluid are represent the process of metasomatism which is a process of metamorphism in which the chemical constituent of hydrothermal fluid reacts with the country rock. As a result of which metamorphic rocks are produce.
