Question 1

How does pumping oil contribute to land subsidence?

Accepted Answer

A)  Oil reacts with the soil causing it to fuse and take up less space. 
B)  Oil pumps increase the weight on the ground causing the ground to sink. 
C)  Oil is removed, which removes the buoyant support it provided for the earth material, causing it to be more compacted. 
D)  Oil reacts with the soil causing it to swell and take up more space. 
E)  Removing hot oil cools the earth and causes it to contract.
