Across
  1. 2. all of the water on Earth (lakes, oceans, clouds)
  2. 5. Earth's zero point of longitude, which passes through Greenwich, England
  3. 6. identical sets of these were found on different continents, supporting the theory of continental drift
  4. 10. imaginary line in middle of Earth dividing it into northern and southern hemispheres. Has a parallel of latitude 0°
  5. 12. Pangea, Gondwana, and Laurasia are examples of this
  6. 13. angular distance of a place north or south of the Earth's equator
  7. 14. a theory proposed by Alfred Wegener in 1912 where continents shift position on Earth's surface
Down
  1. 1. plate boundaries that occur where plates are spreading apart
  2. 3. all of the gases surrounding Earth (five layers)
  3. 4. the solid parts of the Earth; non-living (rock, soil, and landforms)
  4. 7. all living organisms on Earth (plants, animals, bacteria)
  5. 8. theory that Earth's outer layer is made up of large, moving pieces called plates. All of Earth's land and water sit on these plates
  6. 9. plate boundaries that occur where plates are sliding past one another
  7. 11. plate boundaries that occur where plates are pushing together
  8. 15. angular distance of a place east or west of the meridian at Greenwich, England
