What is a Focus?
Practice Version
Focus:
The underground point where an earthquake starts. Focus. The focus is the exact location beneath the Earth's surface where the earthquake begins.
Example:
Imagine you're trying to find the source of a mysterious noise in your house. Just as you might trace that noise back to a hidden spot, perhaps under the floorboards or within the walls, scientists pinpoint the origin of an earthquake beneath the Earth's surface. This underground starting point, known as the earthquake's focus, is like the hidden source of the noise, where the initial rupture occurs, sending vibrations through the ground just as a sound would ripple through your home.
