Question 26 

Rock has a response to stress similar to that of taffy. Crust that is close to the surface and cooler is more likely to be brittle and to break when stressed. Increase the pressure, however, and the rock will heat up, becoming ductile. Under heat and pressure, it will change its shape rather than break. Both brittle and ductile responses to stress are evident in 

 jointing.

 mountain ranges. 

seafloor spreading. 

stream flow.

Question 27 

Anticlines are ________________________? 

 folds with the oldest rocks in the middle 

folds whose LIMBS dip away from the axial plane

 upfolded or arched rocks 

all of the other answers

Question 28 

_____________ are bends in the rock strata and generally represent the ductile response of rock strata to compression within the earth’s crust. 

Joints 

Normal faults 

Folds 

Reverse faults

Question 29
