Elina [12.6K]

Answer:

Types of minerals change in heated<u><em> metamorphic </em></u>area rock. A record of biological time can be found in <u><em>sedimentary</em></u> area rock. Matter changes state from liquid to solid to form<u><em> igneous </em></u>area rock

Explanation:

Metamorphic rocks can be described as a type of rocks which arise by the phenomenon of metamorphism. Immense heat and pressure changes previous rocks (sedimentary, igneous or other metamorphic rocks) into metamorphic rocks.

Sedimentary rocks can be described as the type of rocks which are made by the deposition of minerals or organic particles and hence, help in evolutionary studies.

Igneous rocks can be described as the rocks which are made from lava or magma (hence changing state from liquid to solid).
