What type of rock forms when soil is subjected to intense pressure?

The correct choice is metamorphic rock, which forms when pre-existing rock types, including sedimentary, igneous, or other metamorphic rocks, undergo significant changes due to intense heat and pressure. This process, known as metamorphism, alters the mineral composition and structure of the rock without the rock melting.

While sedimentary rocks are formed from the accumulation and compaction of mineral and organic particles, they are not the result of intense pressure applied to soil alone. Sedimentary rocks typically form at or near the Earth's surface and do not experience the high-pressure conditions characteristic of metamorphic rock formation.

Igneous rocks are created from the cooling and solidification of molten rock, called magma or lava, rather than through pressure applied to existing soil or land.

Organic rock is actually a type of sedimentary rock that is composed of organic materials, like plant debris or shells, rather than being a category that results from pressure.

Thus, when soil or any type of rock material is subjected to intense pressure over time, the result is the transformation into a metamorphic rock.
