Earth's Changing Surface [Types of Faults and Formations]

The amount of stress determines the type of fault that forms, and we usually categorize that sense of stress in three different ways, select the 3-types of stress categories

• Compression

• Sheer

• Tension

• Reverse uplift

Tensional stress happens at _______ plate boundaries

• Convergent

• Transfrom

• Divergent

• Slip-Strike

Compressive stress happens at ________ plate boundaries

• Convergent

• Divergent

• Transform

• Subduction

Shear stress is experienced at _______ boundaries; also known as strike-slip faults.

• Convergent

• Divergent

• Transform

• Subduction

What is a reverse fault?

• When compressive stress is applied, squeezing and shortening the terrain

• When tension is applied, pulling and elongating. If this material were ductile, it would stretch and get thinner, but brittle rocks will break instead

• A strike-slip fault, they don't move in a vertical motion. They are formed horizontal shear stress.

• It's your fault, not mine.

What is considered a "normal fault"

• A strike-slip fault, they don't move in a vertical motion. They are formed horizontal shear stress.

• When tension is applied, pulling, and elongating. If this material were ductile, it would stretch and get thinner, but brittle rocks will break instead

• When compressive stress is applied, squeezing, and shortening the terrain

• Ok, it's my fault not yours.

What is the Elastic Rebound Theory?

• The study of earthquakes

• There is energy stored in an object when it is under temporary strain

• Potential energy will change to kinetic energy.

• Theory that rocks that are strained past a certain point will either fracture, spring back to their original shape or deform in shape.

What is brittle deformation?

• The bending and flowing of a material (without cracking and breaking) subjected to stress.

• A permanent change in shape or volume, in which a material breaks or cracks.

• squeezes rocks together till it folds or break

• A type of deformation in which the material returns to its original shape when stress is relaxed

What is ductile deformation?

• A permanent change in shape or volume, in which a material breaks or cracks.

• The bending and flowing of a material (without cracking and breaking) when subjected to stress.

• Squeezing rocks together till it folds or break

• To draw or stretch tight beyond the normal limits

What is elastic strain?

• The bending, tilting, and breaking of Earth's crust

• Stress that stretches rock so that it becomes thinner in the middle

• When material returns to its original shape when stress is relaxed

• To draw or stretch tight beyond the normal limits
