Explanation:

1. A fault is a fracture/zone between rock blocks; an earthquake is the sudden release of energy along a fault that causes shaking.
2. Most earthquakes occur along tectonic plate boundaries, where plates interact (collide, slide, pull apart).
3. Earthquakes form when built-up stress in rock (from tectonic plate movement) exceeds the rock's strength, causing sudden elastic rebound along faults, releasing energy as seismic waves.
4. Body waves travel through the Earth's interior (P and S waves), while surface waves only travel along the Earth's surface and cause more intense ground shaking.
5. Earthquake strength depends on the amount of stress released, the area of the fault that slips, and the depth of the slip—larger slip areas, greater stress, and shallower depth create stronger earthquakes.
6. The mantle is under high pressure, making rock more ductile (it deforms slowly instead of breaking suddenly), so sudden slip and energy release (earthquakes) are rare.

Answer:

1. A fault is a fracture/weak zone in Earth's crust where rock blocks can move past each other. An earthquake is the sudden, violent release of energy along a fault that causes ground shaking and seismic waves.
2. Most earthquakes happen along the boundaries of Earth's tectonic plates.
3. Earthquakes are caused by the sudden elastic rebound of rock that has been deformed by built-up stress from tectonic plate movement. When the stress exceeds the rock's strength, the rock breaks along a fault, releasing energy as seismic waves.
4. Body waves travel through the interior of the Earth (including P and S waves), while surface waves only travel along the Earth's surface and are responsible for most of the damage during an earthquake.
5. Some earthquakes are stronger than others because they involve a larger area of a fault slipping, a greater amount of built-up stress being released, or shallower slip depth (shallower earthquakes transfer more energy to the surface).
6. Few earthquakes happen in Earth's mantle because the mantle rock is under high pressure, making it ductile (it deforms slowly instead of breaking suddenly), so sudden, energy-releasing slip (like in earthquakes) is uncommon.
