Difference between shear and thrust?

Question

Both are related to stresses acting on the earth's rock materials?

Answer 1

Shear = cut and thrust = push.

Answer 2

The force that causes motion between layers is shear.
Thrust is any push force acting on a system.

Answer 3

Shear is movement between two plates. Thrust is the force causing one of them to move.

Answer 4

SHEARA:
A straining action wherein applied forces produce a sliding or skewing type of deformation. A shearing force acts parallel to a plane as distinguished from tensile or compressive forces, which act normal to a plane. Examples of force systems producing shearing action are forces transmitted from one plate to another by a rivet that tend to shear the rivet, forces in a beam that tend to displace adjacent segments by transverse shear, and forces acting on the cross section of a bar that tend to twist it by torsional shear (see illustration). Shear forces are usually accompanied by normal forces produced by tension, thrust, or bending. Shearing stress is the intensity of distributed force expressed as force per unit area.

THRUST:
The force that propels an aerospace vehicle or marine craft. Thrust is a vector quantity. Its magnitude is usually given in newtons (N) in International System (SI) units or pounds-force (lbf) in U.S. Customary Units.
A newton is defined as:
1 kilogram mass times an acceleration of 1 meter per second squared.
One newton equals approximately 0.2248 lbf

Answer 5

Shear is that type of force that causes or tends to cause two contiguous parts of the same body to slide relative to each other in a direction parallel to their plane of contact. (eg Plates)

Thrust is that whihc force ( a molten rock) into pre-existing rock
