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