GEOLOGY

Detailed explanation-1: -A fault is a fracture, or break, in Earth’s lithosphere, along which blocks of rock move past each other. A sudden release of stress in the lithosphere causes an earthquake.

Detailed explanation-2: -The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.

Detailed explanation-3: -The sudden release of stress in the lithosphere. A break in the earth’s lithosphere along which movement occurs is a(n) fault. When stress builds up in the lithosphere, either along an existing fault or in unfractured rocks, the rocks will eventually fail in a sudden release of energy called a(n) earthquake.

Detailed explanation-4: -A fault is a break in a rock mass along which movement has occurred. Faults occur when the rock is brittle.

Detailed explanation-5: -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.
