2. Week 12 CRCT Questions

3. 1. In an area where the lithosphere is being pulled apart, the crust Folds and crumples into mountains Breaks into blocks separated by faults Slides down into the mantle Develops a subduction zone

4. 2. When two plates carrying continental crust collide, the rock of the continents Folds Melts Expands stretches

5. 3. The movement of huge blocks of rock along a fault can produce a. Lava plugs b. Volcanoes c. fault-block mountains d. Folded mountains

6. 4. What features of Earth are produced by the movement of lithospheric plates? Solid masses of iron and nickel Liquid masses of iron and nickel Red hot magma Mountains, volcanoes, and volcanic islands

7. 5. Plate tectonics describe movements mainly in Earth’s crust Earth’s mantle Earth’s outer core Earth’s inner core

8. 6. As the distance increases from a mid ocean ridge, the rocks Grow younger Grow older Do not change in age Become liquid

9. 7.A convection current of magma is made up of A rising more dense liquid and a sinking less dense liquid A rising less dense liquid and a sinking more dense liquid Liquids of the same density Solids of different densities.

10. 8. What can fossils reveal about the Earth’s past? Only changes in Earth’s climates over time Only changes in Earth’s surface features over time Changes in Earth’s climates and surface features over time Present climates and surface features of Earth

11. 9. Along a normal fault, the block of rock above the fault plane Slides down relative to the other block. Slides up relative to the other block. Slides past the other block. Does not move.

12. 10. Along a reverse fault, the block of rock above the fault plane • Moves down relative to the other block. • Movespast the other block. • Moves up relative to the other block. • Does not move.
