Normal faulting occurs where tensional stresses cause the crust to be stretched.
Grabens produce an elongated valley borded by horsts.
True or False
Most mountain building occurs at Convergent plate boundaries.
True
False
________________ provides the compressional forces that fold, and metamorphose the thick layers of sediment.
colliding plates
grabens
divergent boundaries
True or False
At a convergent boundary, a collision between two plates carrying continental crust will result in the formation of folded mountains.
True
False
When two tectonic plates collide, the continental crust usually rises over the
oceanic crust. What is the reason behind this?
Denser than continental crust
Thicker than continental crust
Thinner than continental crust
Less dense than oceanic crust
It refers to the force exerted over an area which causes a deformation in the Earth's crust.
Stress
Strain
It is a type of crustal deformation that were formed by brittle strain.
Folds
Faults
TRUE OR FALSE:
Too much compression on folds may lead to the formtion of faults.
True
