Detailed explanation-1: -When the energy and pressure build up enough to overcome the friction, the plates move past each other along the fault. The energy and pressure are released in the form of seismic waves that shake the surface as they move through it-like ripples on water.
Detailed explanation-2: -As the plates move past each other, they sometimes get caught and pressure builds up. When the plates finally give and slip due to the increased pressure, energy is released as seismic waves, causing the ground to shake. This is an earthquake.
Detailed explanation-3: -Earthquakes occur along fault lines, cracks in Earth’s crust where tectonic plates meet. They occur where plates are subducting, spreading, slipping, or colliding. As the plates grind together, they get stuck and pressure builds up.
Detailed explanation-4: -The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth’s crust and cause the shaking that we feel.
