How regional (prograde) occur?
Prograde metamorphism involves the change of mineral assemblages (paragenesis) with increasing temperature and (usually) pressure conditions. These are solid state dehydration reactions, and involve the loss of volatiles such as water or carbon dioxide.
How does (prograde) occur?
In general, the changes in mineral assemblage and mineral composition that occur during burial and heating are referred to as prograde metamorphism.
How does contact (prograde) occur?
In general, the changes in mineral assemblage and mineral composition that occur during burial and heating are referred to as prograde metamorphism.
Why regional (prograde) occur?
These are solid state dehydration reactions, and involve the loss of volatiles such as water or carbon dioxide. Prograde metamorphism results in rock characteristic of the maximum pressure and temperature experienced. Metamorphic rocks usually do not undergo further change when they are brought back to the surface.
Is earth reteograde or prograde?
it is Prograde
Does Eris have retrograde rotation or has prograde?
Prograde
Why does contact (prograde) occur?
The size of the aureole depends on the heat of the intrusion, its size, and the temperature difference with the wall rocks.
Is Earth a retrograde or prograde rotation?
prograde rotation
Is the earth's rotation prograde or retrograde?
It is prograde. That's counterclockwise, viewed from above the North Pole.
Does regional metamorphism occur under volcanoes?
Yes they do occur under volcanoes
Does Venus have a retrograde revolution?
Prograde. In our solar system, prograde is counterclockwise rotation or revolution. Retrograde is clockwise rotation or revolution.Clockwise and counterclockwise are "as viewed from above the Earth's north pole".All solar system planets have a prograde rotation except Venus and Uranus which have retrograde rotation.All the planets have prograde orbital motion (revolution) around the Sun.So, Mercury has prograde motion in both cases.
Does saturn have a prograde rotation?
Yes.
