Endogenic Processes

It comes from the greek word “meta” meaning change and “morph” meaning form. So it literally means “change of form”.

What is Metamorphism?

What are the 3 types of metamorphism?

What type if metamorphism that involves deformation like shearing and grinding that takes place in the fault zone?

What type if metamorphism that occurs when a body or rock is intruded by magma?

What type if metamorphism which the alteration of rocks by both thermal and mechanical means over a whole region?

It is seen as an energy from the motion of the molecules of bodies such as Earth and maybe transferred by conduction, convection, or radiation.

It is a process by which heat or electricity is directly transmitted through a substance.

It is the transfer of heat by the circulation or movement of the heated parts of a liquid or gas.

It is the transfer of heat in a wave-like motion through empty spaces.

What are the 3 main sources of heat?

What is the force per unit area that is placed in a rock?

What are the 3 types of stress?

It stresses act towards each other, pushing or squeezing rock together. It’s the most common stress.

It stresses act in opposite direction, pulling rocks apart or stretching it.

It stresses towards or away from each other but they do so long different line of action, causing the rock to twist or tear.

How do rocks behave in different types of stress?

When rock is stressed, what series of changes does it go through?

The rock strains but change is not permanent. If the stress is removed, the rock will return to it’s original shape and size.

It begins when stress reaches a point called Elastic Limit. Permanent changes occur. If the stress is then removed, the deformation is permanent, and the rock is no longer returned to its original shape and size.

The stress causes the rock to break. In general, high temperatures and pressure favor ductile behavior and make fractures likely to occur.
