The rocks constituent minerals can become perpendicularly aligned from pressure, they can change from hydrous minerals to non-hydrous minerals, or they can recrystallize into larger crytals from from heat. In the case of contact metamorphic rocks, there can also be a transfer of elements from the plutonic intrusions into the host rock.

∙ 12y agoWhen a rock is plasticly deformed, it must be in a high enough temperature and under enough pressure that it does not crack, but instead shears under stress. When this happens, the mineral grains in the rock sheer or compress along with the rock, causing them to elongate or flatten.

In the process of elastic rebound as a rock becomes stressed it first?
deforms
What is a rock that deforms like a piece of molded clay called?
plastercine
When solid rock deforms and returns to its original shape it has undergone?
When a solid rock deforms and then returns to its original shape, it is known as elastic deformation. The rock doesn't break under pressure, but instead changes its form, and after the pressure is released the rock goes back to its shape.
When rock is energy builds up in it Seismic waves occur as this energy is?
when rock is -----, energy builds up in it. Seismic waves occur as thisenergy is--. the answer is plastically deformed increased
A process by which rock deforms like a rubber band being stretched is called?
The force causing the change in the shape of rock is called stress. The change of shape in the rock is called strain. If the stress does not cause a permanent change in the shape of rock, it is called elastic deformation. If the change is permanent, it is called plastic deformation.
How does the lithosphere respond to the weight of glacial ice?
It plastically deforms, pressing down into the softer athenospehere.
What happens when compression force are exerted on layer rock?
They deform, first elastically then plastically.

What is the name of a rock when it becomes permanently deformed without breaking?
When a rock deforms without breaking it is often called "folded".erosion
When a rock deforms as it moves and then snaps back together it causes what?
a seismic wave, earthquake, landslide
When rock is energy builds up in it Seismic waves occur as this energy is?

What is the weak upper portion of the mantle which behaves plastically?
the asthenosphere
What is the process by which the shape of a rock changes because of stress?
This is technically known as strain. If the change in shape occurs by fractures forming through the rock this is known as a brittle deformation. If however the rock deforms like a piece of clay being squashed this is known as ductile deformation.
What deforms by plastic flow?
asthenosphere
Can the rocks in the crust move around more easily than the rocks in the lower mantle?
No, crustal rock is cold, hard, and brittle while mantle rock is hot, soft, and plastic. Crustal rock fractures under stress while mantle rock deforms and slowly flows under stress.
