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