(8) Unit 2 CW 1

4. the physical force exerted on an object
6. the ability to do work
9. a rate of inclination; a slope
12. dark, fine-grained rock that makes up most of the oceanic crust
15. layer of molten metal surrounding the inner core
16. the movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to another
18. transfer of thermal energy from one material to another by electromagnetic waves
20. the layer of hot, solid material between Earth’s crust and core
21. crust that lies beneath the ocean
22. type of force that destroys and wear away landmasses through processes like erosion and weather
25. All the living things on Earth. It comes from the word “Bio” which means “life.”
27. the amount of matter in an object
28. the crust that forms the continents
30. All the rock, soil and sediments that makeup Earth’s land. It comes from the word “Geo” which means “Earth.”
31. process of breaking down of rocks and land due to forces such as gravity, wind, water and ice
32. All the oceans, rivers, lakes and water on Earth. It comes from the word “Hydro” which means “water.”
33. type of force that shapes the land’s surface by building up mountains and other landmasses.
34. the rigid layer of the lower-mantle and extends down to Earth’s core

1. this layer is formed with the crust and rigid upper mantle, and is above the asthenosphere
2. Movement caused by warm fluids rising and cooler fluids sinking.
3. The area subject to flooding during a given number of years according to historical trends.
5. vibrations that travel through Earth carrying the energy released during an earthquake
7. a rock that is usually a light color and has coarse grains and makes up most of the continental crust
8. layer of earth that is made mostly of the metals iron and nickel, and consists of two parts
10. the process of moving things from one place to another.
11. a dense sphere of solid metal
13. All the gases surrounding the earth. It comes from the word “Atmos” which means “air.”
14. the measurement of how much mass of a substance is contained in a given volume
17. transfer of thermal energy between materials because of collisions between particles
19. the soft layer of the upper-mantle on which the lithosphere floats
23. the amount of space that matter occupies
24. Process in which sediment is laid down in new locations
26. the layer of rock that forms Earth’s outer surface, which includes both dry land and the ocean floor
29. A description of surface features of land.
