If the rock was exposed to pressure equally from all directions, then it will likely not show foliation
Because metamorphic rocks from very deep underground, they have to be brought to the surface by some geologic processes before they are exposed. There are many processes that could do this, but the most common is a mountain building event. Mountainous areas often have very large areas of exposed metamorphic rocks.

A metamorphic rock is an igneous, sedimentary, or another metamorphic rock that has been: 1) squeezed by incredible pressures deep underground, 2) has been exposed to very hot fluids, 3) has been exposed to very high temperatures without melt occurring, 4) combinations of numbers 1-3. Rock exposed to these conditions can be metamorphosed, altering its structure, mineral alignment, and possibly its chemistry.
Shale that is exposed to high temperature and pressure and turned to slate is an example of the metamorphic process.
When limestone is exposed to intense heat and pressure, it metamorphoses into a rock called marble. Marble is a metamorphic rock that forms when the calcite crystals in limestone recrystallize and interlock.

Insects can perform their life functions in and around the cracks and fissures of exposed weathered metamorphic rock.

Metamorphic.
When limestone is exposed to intense heat and pressure, it metamorphoses into a rock called marble. Marble is a metamorphic rock that forms when the calcite crystals in limestone recrystallize and interlock.
Metamorphic rock which is exposed to increasing heat and pressure from various sources can eventually melt. If this melt then solidifies, it has become igneous rock.
it melts.
If igneous rocks are exposed to extreme pressure and heat, they are likely to recrystallize into new igneous rocks. On the other hand, if sedimentary rocks are exposed to extreme pressure and heat, they are likely to metamorphose into metamorphic rocks.
No. They will either be subducted into the mantle or uplifted and/or exposed to erosion.
