Answers
Answer:
a/ Earthquakes and volcanic activity occur along the plate boundaries, or fault lines. ... The sliding of the plates against each other causes slow-moving earthquakes, or slow slip events, which occur over a period of many weeks. The movement is so slow that humans are not aware of the earthquake at all.
b/ Endogenetic Movements
Endogenetic forces sometimes produce sudden movements and at the other times produce slow movements. Sudden movements like earthquakes and volcanoes cause mass destruction over the surface of the earth. While diastrophic movements are rather slow.
c/ Thus, when they are acted upon by differential stress, they tend to fracture. Most natural earthquakes are caused by sudden slippage along a fault. Faults occur when brittle rocks fracture and there is displacement of one side of the fracture relative to the other side.
d/ But, as the glaciers melt and their load on the plate lessens, there is a greater likelihood of an earthquake happening to relieve the large strain underneath. Even though shrinking glaciers make it easier for earthquakes to occur, the forcing together of tectonic plates is the main reason behind major earthquakes.
