Differences in _____ resulted in the formation of Earth's three (3) main layers (crust, mantle, core).

• density
• mass
• temperature
• acidity

Earth's layers formed because:

• Gravity pulled denser materials toward the center while lighter materials rose toward the surface.
• Wind and water slowly sorted Earth’s rocks into layers over millions of years.
• Plants and animals created stacked layers as they decomposed.
• Earth’s rotation pushed heavy materials outward and light materials inward.

Which of the following statements about the sources of Earth's internal heat is INCORRECT?

• Some of Earth's internal heat comes from radioactive decay of elements.

• Earth's interior is heated by energy left over from its formation.

• Friction from Earth's rotation is a major source of internal heat.

• Compression due to gravity contributes to Earth's internal temperature.

Which process is primarily powered by the Earth's internal heat energy?

• The creation of wind currents

• The movement of tectonic plates

• The orbit of the Moon around Earth

• The rise and fall of ocean tides

Without the heat from inside, Earth would be geologically still so there would be no mountain building, no earthquakes, and no plate movement.

James is curious about what lies deep below Earth’s surface and wonders why there isn’t much research about these layers. Why is there very little research done about the layers deep below Earth’s surface?

• Scientists believe these layers don’t change, so studying them isn’t necessary.

• The layers are too hot and under too much pressure for us to reach or study directly.

• Earth’s layers are too soft to collect samples from without damaging them.

• There’s no technology of any kind that can be used detect what lies beneath Earth’s crust.

• Continental crust is thicker and less dense than oceanic crust.

• Continental crust is thinner and less dense than oceanic crust.

• Continental crust is thicker and more dense than oceanic crust.
