Identify the best explanation for the important role of the liquid outer core, and not the solid mantle, in forming Earth's magnetic field.

• The mantle moves very slowly compared to the outer core.

• The outer core moves more quickly than the mantle and has a higher metal content.

• The outer core is mostly iron and nickel and the mantle is mostly silicon and oxygen.

• The outer core is closer to the center of the planet than the mantle.

The core consists of two different parts. Which characteristic best describes their major difference?

• Metal, rock

• Iron, nickel

• Older, younger

• High pressure, low pressure

As a natural part of the planet's evolution, Earth is cooling. Which prediction is the most likely outcome of this cooling?

• Gradually, convection in the mantle will move more quickly.

• Gradually, the solid core will become larger and the liquid core smaller.

• Gradually, convection in the liquid core will move more quickly.

• Gradually, the core will be replaced with solid rock.

Some volcanoes occur far from plate boundaries in locations called hot spots. Which of the following would best explain the presence of hot spots?

• Hot spots are locations of thinner crust and upward convection of mantle.

• Hot spots are locations of downward convection movement of mantle.

• Hot spots are locations of upward convection movement of outer core.

• Hot spots are locations of Earth's emerging magnetic field lines.

The type of stress that pulls on and thins an area of Earth's crust is called:

• Torsion

• Tension

• Shearing

• Diverging

Which of the following statements about mid-ocean ridges is true?

• They are the source of the material that forms the new ocean floor.

• They occur where the oceanic crust is the most dense.

• They are major subductions zones.

An earthquake occurs along a fault when:

• Energy in the rock along the fault does not change for a long period of time

• Stress in the rock along the fault causes magma to rise up through the fault

• Enough energy builds up in the rock along the fault to cause the rock to break or slip

• Energy in the rock along the fault is changed to heat

Select the best explanation for why this statement is true or false: All island chains are formed by a plate of oceanic crust moving over a hot spot.

• True: ALl island chains are formed by a plate moving over a hot spot

• False: island chains cannot form over hot spots

• False: Island chains can be formed either over hot spots or convergent boundaries

• False: island chains can only form over divergent boundaries

Rate yourself on how comfortable you feel with the material.

1 means you have no idea what's going on, and 4 means you could teach it.
