    Earthquakes happen as large blocks of the Earth’s crust move suddenly past one another because of the force of plate tectonics. These blocks of the Earth’s crust meet at cracks called faults. Sometimes those pieces do not slide smoothly past one another. There can be friction along the fault – jagged edges that snag the blocks of rock. This makes it difficult for them to move past each other. Sometimes they get stuck together temporarily. When the pieces of rock overcome the snags, energy is released. The release of energy causes shaking at the ground surface.

    The location inside the Earth where an earthquake begins is called the focus. The point at the Earth’s surface directly above the focus is called the epicenter. The strongest shaking happens at the epicenter.

    Landslides occur when the hill or mountain side is unstable.

    Shocks and Vibrations - Earthquakes, typically those of 4.0 magnitude and above, can can create stresses that weaken slopes. Earthquakes tend to produce the largest and most destructive landslides.

    the respond is C. the concentration is the element at which the capability is released in a earthquake so as that narrows it to B & C. because of the fact the concentration could be released at 5 miles under the floor that's released is a physique wave.
