Multiple Choice

Which statement best describes why S-Waves are NOT recorded by seismographs in certain areas?

• Seismographs do not record s-waves.
• S-waves travel in a different direction than p-waves.
• The earthquake was not strong enough to produce s-waves.
• The s-waves are stopped by the liquid outer core.

Multiple Choice

How do you think these tiny gas and dust particles could eventually form a planet? What forces might be involved?

• Gravity

• Magnetism

• Friction

• Pressure

Multiple Choice

The graphic shows the stages in the development of the solar system. Which statement best describes the process of the formation of the solar system?

• Gravity pulled the gas and dust together.

• A black hole pulled the gas and dust together.

• Magnetism attracted the gas and dust together.

• An explosion pushed the gas and dust together.

Multiple Choice

Which statement is true about gas giants?

• Gas giants have gaseous cores and rocky surfaces because the planets are far from the sun.

• Gas giants formed close to the sun and contain deep, gaseous atmospheres.

• Gas giants contain ices because these planets formed far enough from the sun that these materials could condense.

• Gas giants contain no rock or metals because the planets are too cold for these materials to condense.

Open Ended

Where does all of the heat inside the Earth come from?

Multiple Choice

What are the two main sources of heat generation in Earth's interior as described in the lesson?

• Gravitational potential energy

• Nuclear fusion

• Chemical reactions

• Solar radiation

Multiple Choice

How did Earth's layers form?

• Through tectonic movements

• By gravitational separation

• From meteor impacts

Multiple Select

What are the changes in Earth's interior over time as depicted in the diagram?

• Uniform mixture of molten materials

• Spherical layers with different properties

• Gravity pulling dense materials toward the center

• Solid state of Earth

Multiple Choice

What are some similarities and differences between the lithosphere and the crust?

• The lithosphere is thicker than the crust.

• Both are outermost layers of the Earth.

• The crust is a physical layer.

• The lithosphere contains the mantle.
