EASC 101- Lecture 6

Amount of force applied to an area is called

• strain

• stress

• thrust

• push

The deformation that results from the application of a force is called

• strain

• stress

• thrust

• push

Stress applied unequally from different directions is called

• compressional stress

• disproportionate force

• irregular stress

• differential stress

Differential stress that shortens is called

• compressional stress

• disproportionate force

• irregular stress

• differential strain

Stress that elongates or pulls apart is called

• compressional stress

• disproportionate force

• tensional stress

• differential stress

Rocks near the surface undergo

• ductile deformation

• subtle deformation

• radical deformation

• brittle deformation

Rocks at depth undergo ductile deformation because

• a. pressure is high

• b. temperature is high

• c. water content is high

• d. a and b above

The line produced by the intersection of an inclined rock with a horizontal plane is called the

• dip

• fault

• fold

• strike

The angel of inclination of the surface of a rock or fault measured from a horizontal plane is called the

• dip

• fault

• fold

• strike

When rocks are deformed into wavelike undulations they form

• faults

• thrusts

• folds

• veins
