The picture shows a model of Earth's layers that Kenyatta was making. What mistake has Kenyatta already made in his model?

• He marked the inner core as a gas.

• He marked the outer core as a liquid.

• 
  He put the outer core in the wrong location.

• He put the inner core in the wrong location.

Which layer is the hot, convecting layer of Earth that lies directly under the crust?

• the atmosphere

• the outer core

• the inner core

• the mantle

Which of the following shows where the asthenosphere, mantle, and core would be labeled on a model of Earth's layers?

• 
• 
• 
• 

The diagram shows the layers of Earth.

Which statement best describes Layer 3 and Layer 5?

• Layer 3 is the crust and Layer 5 is the mantle; both layers are hotter than Layer 1.

• Layer 3 is the mantle and Layer 5 is the crust; both layers are hotter than Layer 1.

• Layer 3 is the mantle and Layer 5 is the crust; both layers are cooler than Layer 1.

• Layer 3 is the crust and Layer 5 is the mantle; both layers are cooler than Layer 1.

The graph shows the percent of elements in Earth's crust.
If you were to dig up a random 200-kilogram sample of rocks, which element would you expect to represent about 5.2 kilograms of the sample? (multiply each % by 2 to get the answer)
