• Tropical storms
• Earthquakes
• Tornadoes 

Which of the following would be an accurate feature to include in a model of Earth?

• A crust that is the thickest layer
• An inner core that contains oceans
• A thin mantle in the center of the model
• A liquid outer core below the mantle

At which type of plate boundary will a trench most likely form?

• Convergent 

Which of the following best describes Earth’s asthenosphere?

• Liquid rock that can reach the surface
• Solid rock that is broken into plates

A student constructs a clay model of Earth to show its layers. What property is the model able to share with the real Earth? The model will have layers that are the same -

• temperatures as the real Earth.
• positions as the real Earth.
• state of matter as the real Earth.
• thickness as the real Earth.
