Give reason behinds earthquake in 150 words
Answers
Answer:
Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. They don't just slide smoothly; the rocks catch on each other.
he 3 main causes of earthquakes?
The main causes of earthquakes fall into five categories:
Volcanic Eruptions. The main cause of earthquake is volcanic eruptions.
Tectonic Movements. The surface of the earth consists of some plates, comprising of the upper mantle. ...
Geological Faults. ...
Man Made. ...
Minor Causes
Explanation:
when the plates move they rub against each other, sometimes getting interlock.this prevents them from moving.for years,forces pushing the two plates from the beneath create tremendous pressure against the edges of the plates. as the pressure continue to build, the strain rips the two plates apart. this sudden ripping of the two plates send waves of high energy in all directions within along the surface of the earth. these waves are called sesmic waves and are felt an earthquake when they reach the surfacethe place from where an earthquake originates is called the sesmic focus. it is the point from where the edges of the plates give way. the point vertically above the seismic focus is called epicenter.
