Across
- 3. is the solid, outermost layer of the Earth, consisting of the Earth's crust and the upper, brittle portion of the mantle
- 4. refers to the process where, early in its formation, the Earth's materials separated based on density
- 5. is the outermost layer of the Earth, made of solid rock
- 11. is an imaginary line that runs around the middle of the planet, dividing it into the Northern and Southern Hemispheres
- 13. is the day when the Earth is tilted farthest away from the sun, resulting in the shortest day and longest night of the year in the Northern Hemisphere
- 15. refers to the movement of the Earth in its orbit around the Sun
- 16. is a layer within the Earth's upper mantle, directly below the lithosphere
Down
- 1. is the moment when the sun is directly above the equator
- 2. is half of the Earth
- 6. refers to the point in Earth's orbit where it is furthest away from the Sun, typically occurring around early July each year
- 7. is the point in Earth's orbit when it is closest to the sun
- 8. is made up of the continents and continental shelves, which are the outermost layer of the Earth's lithosphere
- 9. is the Earth's axis of rotation slowly wobbling over time
- 10. is a liquid layer of the planet's core, situated between the solid inner core and the mantle, primarily composed of molten iron and nickel
- 12. is a solid, dense ball of iron and nickel at the center of the planet
- 14. is the layer of Earth that sits between the crust and the core
