​Explanation

• The thicket part of the model should be the mantle. The thickness of the upper and lower mantles combined is nearly 3,000 kilometers. (The thickness of the inner and outer cores combined is approximately 3,480 kilometers.)

• The thinnest part of the model should be the crust. The thickest part of the crust is only about 80 kilometers, and the oceanic crust is only about 5 kilometers thick in some places.

​Explanation

• ​Inner Core:

  • ​solid

  • ​hottest layer

  • ​under the most pressure

• ​Outer Core

  • ​liquid

​Explanation

• ​Temperatures increase as depth increases.

• ​As you move toward the core, the depth increases, therefore the temperatures also increase.

​Explanation

Just like in a pool, pressure increases as depth increases.
