What is an Earthquake?
What will be an ideal response?
Answer: Earthquakes are sudden movements of the crust. Thousands of earthquakes occur every day. The vast majority of Earthquakes tend to be clustered along plate boundaries, but can also occur inside plate along fractures and fault lines. When an Earthquake occurs, the place where Earth's crust actually moves is the focus of an earthquake. The focus is generally near the surface but can be as deep as 350 miles below Earth's surface. Directly above the focus on the surface of the Earth is the epicenter.
The energy released at the focus travels worldwide in all directions and at various speeds through different layers of rock. The instrument used to measure Earthquake intensity is the Richter scale, which is a logarithmic scale with a range of 0 to 9.
