Candy Bar Tectonics What are the layers of the Earth? Earth’s Crust Upper Mantle (Asthenosphere) Lower Mantle & Core Cracks in the Earth’s surface along which rocks move are called faults. The Earth’s crust is divided in large pieces called plates. Tension is a force that pulls on the plates of Earth’s crust causing them to move apart. Compression is a force that pushes on the plates of Earth’s crust causing them to move together. Shearing is a force that pushes on the plates of Earth’s crust causing one to move in one direction and the other plate in the opposite direction. An earthquake occurs when parts of the Earth’s crust moves suddenly along a fault.
