Main sources of stress that cause rock deformation?
Crustal unloading
What builds up in fault zones when crustal blocks stick together?
Stress
Which type of stress produces most crustal deformation?
Tectonic stress, caused by the movement of Earth's tectonic plates, produces the most significant crustal deformation. This stress results in the formation of features like mountains, faults, and earthquakes as the Earth's crust responds to the forces generated by tectonic plate interactions.
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.
What is a bend in a crustal rock?
A bend in a crustal rock is a deformation where the rock has been subjected to stress, causing it to bend without breaking. This bending can occur due to tectonic forces such as compression or extension, resulting in curved layers or shapes in the rock. Bends in crustal rocks are commonly seen in mountain ranges where tectonic forces have been active.
What happens when crustal plates slide past each other?
When crustal plates slide past each other, they create faults along the plate boundaries. Friction between the plates can cause them to get stuck, leading to stress buildup. When this stress is released, it generates earthquakes.
What fault develops in response to horizontal tensional stresses in crustal rocks?
Normal faults develop in response to horizontal tensional stress in crustal rocks. These faults are characterized by the hanging wall moving down relative to the footwall due to stretching and pulling apart of the rocks.

How many plates are in the crustal plates?
There are 14 crustal plates on the earth.
What are the lines on Europa?
The lines are stress fractures in the crustal ice, likely caused by eruptions created by the tidal stresses of Jupiter's gravity, and possibly also Jupiter's magnetic field.
What crustal feature will form when two crustal plates move together?
a fault
What is the evidence for the existence of crustal plates?
Worldwide, the mountains are the evidence of crustal plates.
