GEOLOGY

Detailed explanation-1: -Earthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up ‘elastic strain’ energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake.

Detailed explanation-2: -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.

Detailed explanation-3: -td border: 1px solid #ccc; br mso-data-placement:same-cell; –> Amount of energy released by an earthquake, called its Magnitude, can be measured by the amplitude of the seismic waves produced.-Richter scale (log scale) is used to measure the energy released by earthquakes.

Detailed explanation-4: -1) Energy for Earthquakes comes from radioactive energy in Earth’s mantle. Radioactive decay produces heat that causes convection in the mantle. This movement is transferred to Earth’s crust where movement stores up energy in rocks, like a spring being stretched.
