If exposed to high enough temperatures and pressures, long-buried igneous rock could <em><u>melt and recrystallize</u></em>.
<h3><u>Explanation;</u></h3>
<em><u>Temperature and pressure are among the processes that affect rocks</u></em>, others include weathering, compaction and cementation, erosion and deposition; uplift and subsidence among others.
<u><em>When the temperatures and pressure are high, buried rocks may change into metamorphic rocks. </em></u>When the rock get got enough to melt, they form magma or molten rock and when the magma reaches the Earth's surface it is called the lava, <em><u>which eventually cool and solidify resulting to the formation of new rock.</u></em>
<em><u>Igneous rock becomes sediment due to exposure to chemical and mechanical weathering at the surface or near the surface</u></em>.
Rocks get<em><u> recrystallized when heat and pressure are added</u></em>. This causes the rocks to have larger crystals, equally increasing them inside.
