EVERYDAY SCIENCE

Detailed explanation-1: -When the stresses get too large, it leads to cracks called faults. When tectonic plates move, it also causes movements at the faults. An earthquake is the sudden movement of Earth’s crust at a fault line.

Detailed explanation-2: -An earthquake is the sudden movement of Earth’s crust. 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-3: -When the force of movement finally overcomes the friction, sections of the crust suddenly break or become displaced, releasing the pent-up pressure in the form of seismic waves. This is a naturally occurring earthquake, sometimes referred to as a tectonic earthquake.

Detailed explanation-4: -An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane.

Detailed explanation-5: -Earth waves. Seismic waves are waves that travel through or over Earth. They are usually generated by movements of the Earth’s tectonic plates (earthquakes) but may also be caused by explosions, volcanoes and landslides.
