MDL 3.2 Deformation of the Crust

It is a change in shape or size resulting from applied forces.

• Stress

• Faults

• deformation

• tectonics

At low strain rates more time is available for individual atoms to move and therefore it tend to have a ___________ manner.

• ductile

• electric

• brittle

• none of the above

Permanent wavelike deformation in layered rock or sediment responsible for orogeny.

• faults

• folds

• joints

• ductile

He is the first one who postulate the Continental Drft Theory.

• Albert Wegener

• Dutiot

• Alfred Wegener

• Alfin Wegener

The subduction in convergent boundaries destroy oceanic lithosphere and it leave a ____________ in topography.

• ridge

• volcanoes

• rift

• trench

The problem that was used to reject Continental Drift is that the theory.

• It does not explain the when is the parting away started

• It does not have evidences

• it doesn't have explanation on the mechanism of plates

• there ar so many scientist don't get the idea

Evidence of Continental drift that explain why continent showing South America and Africa fitting together.

• paleoclimate indicator

• rocks and structure

• terrestrial fossils

• jigsaw puzzle fit

A stage of deformation wherein the strain is reversible or can revert the deformation back to its original form when the stress is removed.

• elastic

• ductile

• fracture

• brittle

This is caused by a transform movement. This type of stress cause masses of rock to slip and slide past each other resulting in slippage and translation.

• compression

• shear

• tension

• convergent

The effect of temperature of material in deformations of rocks.

• high temperature less chemical bond, ductile manner

• high temperature stronger chemical bond, brittle manner

• low temperature less chemical bond, brittle manner

• low temperature stronger chemical bond, ductile manner
