1. Unit 2 Review

2. Rigid, upper part of Earth’s mantle and the crust (lithosphere, outer core, inner core) Lithosphere

3. When plates move apart, new crust forms to fill in gaps between the plates ( sliding plates, separating plates, colliding plates) Separating Plates

4. Form when forces inside Earth push up the crust ( fault-block mountains, folded mountains, upwarped mountains) Upwarped mountains

5. Appalachian Mountains are a type of these ( fault-block mountains, folded mountains, upwarped mountains) Folded mountains

6. Which of the following words is not associated to an earthquake: (fault, rift, P-waves, focus) rift

7. Earthquake waves are called ( fault, epicenter, seismic waves) Seismic waves

8. Largest of Earth’s layers; solid, but flows like putty ( crust, mantle, outer core, inner core) Mantle

9. A measure of the energy released by an earthquake (fault, seismograph, P-waves, magnitude) Magnitude

10. Solid, innermost layer of Earth’s interior ( crust, mantle, outer core, inner core) Inner core

11. Leaves, twigs, and other organic material that eventually can be changed to humus (leaching, litter, soil) litter

12. Broad, flat, buildup of basaltic layers, gently sloping sides (shield volcano, cinder cone volcano, composite volcano) Shield volcano

13. Minerals in rocks dissolve or change to other minerals (mechanical weathering, chemical weathering, climate) Chemical weathering

14. Helps reduce erosion on steep slopes (no-till farming, contour farming, terracing) terracing

15. Bowl-shaped part of a volcano; lava often collects here before flowing down the slope ( vent, crater, magma chamber, pipe) Crater

16. Piling yard wastes where they can decompose gradually (leaching, litter, composting) composting

17. Which force creates this type of fault ( compression, extension, shear) Shear

18. Large bodies of magma; caused the Hawaiian Islands to form (fault, rift, hot spots, focus) Hot spots

19. Occurs when rocks are broken apart by PHYSICAL processes (mechanical weathering, chemical weathering, climate) Mechanical weathering

20. Mixture of weathered rock, decayed organic matter, mineral fragments, water, and air (oxidation, weathering, soil) soil

21. The removal of minerals that have been dissolved in water (leaching, litter, chemical weathering) leaching

22. If the resources on Earth became scarce and the environment loses its ability to support the population we have reached our… (population, pollutants, carrying capacity) Carrying capacity

23. Large fractures in rocks along which movement occurs ( plates, faults, epicenter) Faults

24. Tephra forms a small cone of volcanic material; usually produces a short, powerful eruption (shield volcano, cinder cone volcano, composite volcano) Cinder cone volcano
