Answer 1

Answer:

Here is your answer mate

Explanation:

1. Most earthquakes and volcanoes occur because of the movement of the plates, especially as plates interact at their edges or boundaries. At diverging plate boundaries, earthquakes occur as the plates pull away from each other. ... Second, only earthquakes occur when two plates collide (obduct), building a mountain range.
2. Epeirogenic or continent forming movements are radial movements (act along the radius of the earth). Their direction may be towards (subsidence) or away (uplift) from the centre. They cause upheavals or depressions of land exhibiting undulations (wavy surface) of long wavelengths and little folding.
3. Seismic waves are produced when some form of energy stored in Earth's crust is suddenly released, usually when masses of rock straining against one another suddenly fracture and “slip.” Earthquakes occur most often along geologic faults, narrow zones where rock masses move in relation to one another.
