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