  1. 1. Plates: Large, rigid pieces of the Earth's lithosphere that move and interact with one another due to the flow of the underlying mantle.
  2. 3. Block: A block of the Earth's crust that has been displaced along a fault line relative to the surrounding blocks.
  3. 6. The partially molten layer of the Earth's mantle beneath the lithosphere, where convection currents occur and tectonic plates move.
  4. 8. Boundaries: Boundaries between tectonic plates where they slide past each other horizontally, causing earthquakes.
  5. 9. Core: The solid, innermost part of the Earth, composed primarily of iron and nickel under immense pressure.
  6. 10. Forces applied to rocks that can cause them to deform or break, resulting in geological features like faults and folds.
  7. 11. The point on the Earth's surface directly above the focus (hypocenter) of an earthquake.
  8. 14. Currents: Circular currents in the mantle caused by the heating and cooling of magma, which drive the movement of tectonic plates.
Down
  1. 2. Core: The layer of the Earth that lies beneath the mantle and surrounds the inner core. It is composed of liquid iron and nickel.
  2. 4. The layer of the Earth between the crust and the core, composed mainly of silicate rocks. It is divided into the upper mantle and the lower mantle.
  3. 5. (Mohorovičić Discontinuity): The boundary between the Earth's crust and the mantle, where seismic waves change velocity.
  4. 7. Boundaries: Boundaries between tectonic plates where they are moving towards each other, resulting in collisions, subduction, or mountain formation.
  5. 10. Waves: Waves of energy caused by the sudden release of stress within the Earth's crust, typically generated by earthquakes.
  6. 12. The rigid outer layer of the Earth, consisting of the crust and the uppermost part of the mantle, which is divided into tectonic plates.
  7. 13. of Fire: A horseshoe-shaped area in the Pacific Ocean basin characterized by frequent earthquakes and volcanic eruptions, caused by the movement of tectonic plates and subduction zones around the Pacific Plate.
