Question 3

Ocean spreading centers are highlands on the ocean floor, sometimes referred to as submarine mountains.

Which of the following statements best describes the origin of these submarine mountains?

Accepted Answer

A)  Compression at the ridges produce local uplift along the ridge axis. 
B)  The ridges represent upwelling zones from the core which produces a bulge at the earth's surface. 
C)  The ridges are sites of young volcanoes that produce high topography on the sea floor, like Hawaii. 
D)  The mantle beneath the ridges remains hot for millions of years producing an elevated region along the ridge axis because hot rocks are lower density than cold rocks.

Question 7

Evaluate the following statement, addressing what parts, if any, are right and which are wrong:
Jointing in rocks does not affect the flow of groundwater at depths greater than 10- 20m because all fractures close below that depth. Jointing is important, however, to engineers interested in stability of slopes and locating structures because joints can slide or open under gravitational forces on slopes.

Accepted Answer

The first statement isuncorrec
