<u>Erosional deformation
</u> is not a form of rock deformation.
Answer: Option B
<u>Explanation:</u>
Rocks are all the time being subjected to force within the surface of earth because of which these rocks tend to twist, bend or get fractured. This causes the rock to change in their shape or size which is known as the deformation of rock and this deformation is affected by temperature, rock type, time and the pressure. Rocks deform in two ways which are ductile and brittle deformation.
One reason is that the plates float on a hot boiling mentle. when the heat rises and the mentle expands the plates above it also moves.
the other reason is that the plates themselves move.plates have warmer inner sides that tend to rise. and colder outer side that tends to sink. this tug of war between the hotter and colder sides of the plate also helps them move.
