Metamorphism

All of These

foliation

shale - slate - schist

With increasing metamorphism, foliation develops.

It is prominent in areas where surrounding rocks are exposed to heat coming from magma intrusion.

formation of foliation

Marble

Dissolved minerals in the water confined within the rocks react with the heat and trigger a chemical reaction.

The rock contains interlocking and large crystals of minerals compared to minerals found in igneous rocks.

III and IV

All of the above.

in convergent boundaries where plates move towards each other

Slate

I and II are correct.

The dissolved minerals in the fluids react with rocks that the fluids penetrate causing changes in chemical and mineral compositions

The size of the minerals gets smaller as metamorphism increases.

temperature and pressure

Pressure leads to foliation in the rock.

Schist

Granite minerals are still stable at lower temperatures.

Interaction of plates below the spreading oceanic crust creates horizontal movements and deforms the rocks within leading to formations of foliations and cracks

The pressure was the main agent in rock’s formation which aligned the minerals into a new orientation.

greater depth of burial

marble

It indicates an increasing metamorphic grade.

in the mid-ocean ridge in the Atlantic Ocean

Marble

high temperature and pressure

I and II are correct.

heat

Confining Pressure

Differential stress

Shear stress

Contact metamorphism

Regional metamorphism

Dynamic metamorphism

Burial metamorphism

Fault Zone

Hydrothermal

Subduction

Low-grade metamorphism

High-grade metamorphism
