Vocabulary unit 5
Across
- 2. The crust under the ocean, thinner but heavier than continental crust.
- 5. A large piece of Earth's crust that carries land (continents). These plates move very slowly, like a giant puzzle.
- 7. A place where magma rises from deep inside Earth, forming volcanoes. Hawaii was created by a hot spot!
- 12. The edges where tectonic plates meet. This is where earthquakes and volcanoes often happen.
- 15. A place where two plates slide past each other. causing earthquakes, like San andreas fault in California.
- 17. The soft, flowing layer of the mantle below the lithosphere. It's like warm, stretchy plastic, allowing tectonic plates to move.
- 18. A place where two tectonic plates move apart. It can create a new ocean floor. like in the Mid-atlantic.
Down
- 1. A tectonic plate under the ocean. It's thinner but denser than a continental plate.
- 3. The thin, outermost layer of Earth where we live. It's like the skin of an apple compared to the rest of the planet.
- 4. The rigid outer layer of the Earth, made of the crust and upper mantle. It's like the hard shell of an egg.
- 5. The part of Earth's crust that forms land. It is thicker but lighter than oceanic crust.
- 6. A place where two plates push together. It can form mountains or volcanoes, like the Andes
- 8. The liquid layer around the inner core, also made of iron and nickel. It creates Earth's magnetic field.
- 9. The invisible force around Earth that protects us from the Sun's radiation. It makes compasses point north.
- 10. The solid, super-hot center of the Earth, made mostly of iron and nickel. It's like a metal ball deep inside the planet.
- 11. The thickest layer of Earth, between the crust and core. It has hot, moving rock that slowly circulates, like thick soup.
- 13. A deep valley in the ocean floor, formed when one plate sinks under another. The Mariana Trench is the deepest one.
- 14. A huge piece of the lithosphere that moves on the asthenosphere. Their movement causes earthquakes and volcanoes.
- 16. Something melted due to extreme heat, like lava from a volcano.
