Chapter 5 Study Guide

when the indian plate collided with the Eurasian plate, producing the Himalaya Mountains, which type of stress most likely occurred? which type of stress is most likely occurring along the mid atlantic ridge? which type of stress would you expect to find along the San Andreas Fault?

Himalyan Mountains - compression Mid-Atlantic Ridge - tension San Andres Fault - sheer

suppose the new highway is being planned. This proposed road would intersect a transform boundary. What would happen to the highway of a strike- slip fault existed along boundary

The highway would break or crack because the plates slide horizontally

up curved folds in rock are called

anticline

they type of stress that squeezes rock together is

compression

high presure and high temperature will cause rocks to

deform

when no movemnet occurs along the sides of a break in a rock structer the break is

fracture

when a fault is not vertical the rock above the vault plane makes up the

hanging wall

if the force is causing a rock to be slightly different begins to ease what might happen to the rock? What would happen if theforce causing the deformation became greater

if it were to ease it would stay in the same form, but if it became greater it would bend

the state of balence between the thickness of the crust and the depth at which it rides on the atmosphere is called

isostasy

why do you suppose dome mountains do not become volcanic mountains?

magma never breaks the surface of the crust

folds in which both limbs remain horizontal are

monocline

the largest mountain systems are part of still larger systems called

mountain belt

Shearing

shearing bends, twists, or breaks rocks

The increasing weight of mountains causes the crust to

sink

The force that changes the shape and volume of rocks is

stress

a nearly vertical fault in which the rock on eaither side of the fault plate moves horisontaly is called

strike-slip fault

down curved folds in rocks are called

syncline

the type of stress that pulls pulls apart, making them thinner is

tension

suppose glaciers, which are vast fields of slow-moving ice, were to cover much of the earths surface once again What would you expect to happen to those parts of the continents that were covered by ice?

the crust would cave because the ice is heavy

Mount Saint helens in Washington State is an example of a

volcanic mountain
