The fence built on the hill's slop over time will fall. It will not be a sudden process though, but slowly, the fence will bend over till it falls. This will be caused by the erosion, over time little by little the hill will be eroding because of the natural phenomenons like the wind and the rain (depending on the place where the hill is, maybe ice as well), so there will come a point where the basis of the fence that were once in the ground will be uncovered and there will be nothing to hold it, so it will fall.
The correct answer is A. Cumulonimbus.
Explanation
Cumulonimbus, also called vertical development clouds, are a type of cloud that is characterized by expanding from the bottom up through the process of convection, that is, the sun's rays cause the water contained in the cloud to evaporate (take a gaseous state), in this way the water rises until it reaches a point where it condenses to precipitate, but different to other clouds it does not precipitate or become rain but the process is repeated making the cloud develop vertically. Additionally, the rains produced by these clouds are usually quite abundant accompanied by thunderstorms. So, the correct answer is A. Cumulonimbus.
A rift is a type of valley that forms in a subduction zone.
Sea floor spreading is the process in which molten material spews from the mantle, soon to be pressurized. Once there is enough pressure, it pushes the old sea floor into subduction zones causing rift valleys to form. Sea-floor spreading is also a cause of continental drift.
