How does earthquake occur ? Explain.
Answers
Answer:
earthquake are usually caused by when rock underground suddenly fault or breaks. this sudden energy make seismic waves that make a ground shake. Hence, earthquake occurs...........
Answer:
An earthquake is an intense shaking of Earth’s surface. The shaking is caused by movements in Earth’s outermost layer.
Explanation:
The solid crust and top, stiff layer of the mantle make up a region called the lithosphere. The lithosphere isn’t a continuous piece that wraps around the whole Earth like an eggshell. It’s actually made up of giant puzzle pieces called tectonic plates. Tectonic plates are constantly shifting as they drift around on the viscous, or slowly flowing, mantle layer below.
This non-stop movement causes stress on Earth’s crust. 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.
