What is the layer of the Earth with the highest density?

A. The asthenosphereB. The inner coreC. The lithosphereD. The outer core

Which method is NOT used to study the Earth’s interior?

A. Analysis of the Earth’s magnetic field.B. Analysis of seismic waves from

earthquakes.C. Analysis of lava. D. Analysis of samples collected from the

drill hole that extends to the outer core.

The asthenosphere is interesting because…

A. It creates the magnetic field.B. It is the source of Earth’s heat.C. It is a solid with liquid properties. D. It consists of 13 tectonic plates.

Why does density increase as you move towards the center of the Earth?

A. It doesn’t, it decreases.B. The sun’s radiation causes Earth’s

layers to compact.C. Because temperature increases.D. Early in Earth’s history, denser

elements sank towards the center.

The core of the Earth is hotter than the crust because…

A. The crust has cooled over time.B. The core is generating heat from

radioactive decay of some elements.C. The original heat generated from

Earth’s formation is still in the core.D. All of the above.

The Earth’s magnetic field is generated in which layer?

A. The lithosphere B. The inner coreC. The outer coreD. The asthenosphere

The Earth’s magnetosphere protects us from what?

A. Greenhouse gases.B. Solar particles. C. Earthquakes.D. Asteroids.

Which of the following is NOT true about Earth’s magnetic field?

A. It is a temporary magnet.B. It is an electromagnet.C. It extends beyond the Earth’s

crust.D. It is a permanent magnet.

What is NOT true about the Northern and Southern Lights?

A. They are created by meteorites burning up in the atmosphere.

B. They occur at the magnetic poles of the Earth.

C. They are created when solar particles trapped in Earth’s magnetic field collide with air.

What effect does the Sun have on Earth’s magnetic field?

A. The Sun does not affect the Earth’s magnetic field.

B. The Sun’s radiation makes the magnetic field hot.

C. Solar winds distort the Earth’s magnetic field.

D. The Sun’s magnetic field holds the Earth in its orbit.

Convection is responsible for what process on Earth?

A. Plate tectonicsB. Ozone depletionC. MagnetismD. Global warming

Convection currents rely on differences in:

A. PressureB. TemperatureC. PhaseD. Depth

In which layer of the Earth does the convection that drives plate tectonics occur?

A. The asthenosphereB. The inner coreC. The lithosphereD. The outer core

What drives convection in the asthenosphere?

A. Temperature differences between the cooler lithosphere and warmer lower mantle

B. Pressure differences between the lithosphere and lower mantle

C. Temperature differences between the cooler lower mantle and warmer lithosphere

D. Compositional differences between the lower mantle and lithosphere

When liquids and gasses become hotter than the surrounding matter, they …

A. turn into solids and stop movingB. becomes less dense and riseC. give off visible lightD. become more dense and sink

Could the Earth ever lose it’s magnetic field?

A. No, the magnetic field never really changes.

B. Yes, when the magnetic field reverses.

In what way did your electromagnet model NOT represent the Earth’s magnetic field?

A. nail = inner coreB. battery = sunC. coiled wire = outer core

Why is the Earth’s magnetic field invisible?A. It does not produce wavelengths in

the visible spectrum.B. Because the visible light produced

is traveling too fast.C. Because only heat energy is

produced.D. The magnetic lines ARE visible

with special equipment.

Why do gases on the Sun follow the Sun’s magnetic lines and why can you see them?A. The gases are very hot and are

attracted to magnetic fields.B.The gases become charged and

excited and get caught in the magnetic field.

C. Because they are made of iron and become magnetized.

Could we breathe if we lost our magnetic field?

A. Yes, we would still have our atmosphere.

B. No, the solar winds would strip our atmosphere away.

C. Scientists don’t really know the answer.
