- 4. platform: an area of the continent that is filled by sedimentary strata. It also includes igneous and metamorphic rocks
- 5. Shelf: the continental shelf is located near are large landmass in a shallow area. The shelf is technically part of the crust of the continent.
- 8. Science: name for all sciences that seek to understand earth and space
- 10. life-giving gaseous envelope
- 12. the outer layer of the earth
- 15. dense inner sphere
- 16. examines materials that Compose of the earth
- 17. A well tested and widely accepted view that best explains scientific observations
- 20. basin: deep submarine region that is beyond the continental margin
- 22. the largest of the spheres
- 24. explanation that is proposed to explain scientific observations
- 25. dynamic mass of water that is always moving
- 26. rigid outer layer that includes the crust and uppermost mantle
- 29. group of interacting parts that work together to form a complex whole
Down
- 1. subdivision of the mantle
- 2. Shield: large areas of the earth's crust. This is where the mountain building process happens.
- 3. Ocean Trench: these are the deepest parts of the seafloor.
- 6. System:
- 7. Theory: describes the formation of the solar system
- 9. the study of the universe
- 11. study of ocean
- 13. continent is a body of land that has its own continental plate. In the world, there are 7 of these continents: North and South America, Asia, Europe, Antártica, Australia, and Africa.
- 14. Rise: an underwater sediment that is located between the slope of the continent and the abyssal plain. This is the final boundary between the deepest part of the oceans and the continents.
- 18. the sphere that includes all life on earth
- 19. less dense sphere
- 21. plain: these are usually located on the deep ocean floor around 10,000 feet below sea level. These plains cover more than 50 percent of the surface.
- 23. study of the atmosphere and processes that produce the climate
- 27. mid ocean ridge: a mountain chain located on the floor of the ocean. These ridges are formed by the plate tectonics. Most of the time it is near the ocean basin.
- 28. method: the method taken to get an answer to a hypothesis
