Question

Which type of rock is most likely to form because of high heat and pressure?

igneous
magma
sediment
metamorphic

Answer 1

Igneous rock

Granite is an igneous rock that forms when magma cools relatively slowly underground. It is usually composed primarily of the minerals quartz, feldspar, and mica. When granite is subjected to intense heat and pressure, it changes into a metamorphic rock called gneiss.....

Answer 2

Answer:

Metamorphic rock is most likely to form because of high heat and pressure.

Explanation:

• Although they began as a different kind of rock, metamorphic rocks have undergone significant alteration from their igneous, sedimentary, or previous metamorphic forms. When rocks are exposed to extreme temperatures, high pressures, hot mineral-rich fluids, or, more frequently, some combination of these conditions, metamorphic rocks are created. These kinds of conditions can be found deep inside the Earth or where tectonic plates collide.
• The process of metamorphism changes the rocks into denser, more compact rocks rather than melting them. Either by the rearranging of mineral constituents or through chemical reactions with fluids that enter the rocks, new minerals are produced.
• Even rocks that have already undergone metamorphosis might undergo changes due to pressure or temperature. Rocks subject to metamorphism are frequently crumpled, smeared, and compressed.
