An earthquake is caused by tectonic plates getting stuck and putting a strain on the ground. The strain becomes so great that rocks give way by breaking and sliding along fault planes.
Volcanoes are generally found where tectonic plates pull apart or are coming together.
A mountain is usually produced by the movement of lithospheric plates, either orogenic movement or epeirogenic movement.

Yeah, this is just what the Theory of Plate Tectonics explains. In seismically dead planets (such a Mars or the moon), the evidence of tectonics still remains due to the lack of water to erode these features. If the Earth didn't have active tectonics its entire surface would eventually become a peneplain, with little to no evidence of a tectonic past on its surface. Plate Tectonics is only an explanation (which in Science is called a Theory) of the results of seismic activity.

considering the fact it relatively is the way it works. Plate tectonics is the study of how the earth's crust, that are divided into various products, strikes. As they circulate, they the two slide against, collide into or circulate far flung from one yet another. with the aid of doing so, friction between the two specific plates in point out motives the crust to soften into magma to sort magnificient landforms. As greater magma start to nicely up, rigidity builds up and flows out from traces of weaknesses to create volcanoes in time to come back. Earthquakes ensue while the friction equipped up between 2 plates is all quickly realeased and tremors are produced as the two plates objective to realize stability. P and S waves made from an earthquake are somewhat longitudunal waves and transverse waves vacationing with the aid of the earth's crust. those waves stick to the physics equation for waves i.e. speed = frequency x wavelength. the commencing up time and end time might nicely be won and the gap calculated can tell how a strategies away an earth quake occured. inspite of the shown fact that throughout functional circumstances, we don't might desire to make certain how a strategies away an earthquake occured with the aid of fact of technologies. we are in a position to make certain the source of the earthquake and then map the gap using positioning techniques and a map.

the plates move causing presuure at some points thus causing these disasters
