Earth's Structure

4. highest point in the state of SC
5. the semisolid part of the upper mantle, underneath the lithosphere
8. Dense crust layer, made of basalt
11. state of matter of the crust
12. theory that states the continents were all one land mass and have slowly drifted to where they are now
14. is composed of the crust and the upper mantle
15. Less dense crust layer, make of granite
16. outermost layer of earth
18. Scientist that came up with the theory of continental drift
19. the hottest, most dense, innermost layer of Earth
20. Earth's giant landmass from 200 million years ago

1. the state of matter of the mantle
2. the only truly liquid layer of Earth
3. lines on a map that connect points of equal elevation
4. theory that states hot, less dense material below Earth's crust rises toward the surface at the mid-ocean ridge
6. use symbols to portray the land as if viewed from above
7. takes the lines on a topo map and turns it into a 3D replica
9. is the difference in elevation between 2 side by side contour lines
10. scientist that discovered seafloor spreading
13. Highflying aircrafts and satellites above Earth's surface, use sensors and cameras to gather information about Earth's landforms and resources
15. is the transfer of heat by the circulation or movement of the heated parts of a liquid or a gas
17. Earths middle layer, its also the thickest layer
