Total questions: 15
Worksheet time: 11mins
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
Continental drift theory believe that continent start to move apart in this time.
Triassic period
Paleozoic era
Beginning of earth
none of the above
Two blocks of crust pull apart and create space, stretching the crust into a valley.
strike-slip faults
reverse faults
thrust faults
normal faults
Stress is a force acting on a rock per unit area and therefore has units of ____________.
force/area
force added to the measure of area
area/force
force multiply by the measure of area
It appears to weaken the chemical bonds and forms films around mineral grains along which slippage can take place.
pressure
water
gas
heat
It explain the movement of the continent.
Continental Drift theory
theory of geosynclines
Plate tectonics
theory of uniformitarianism
