Sam is creating a computer model to present to his classmates so they can compare the properties of each layer of Earth.

The  ______  should be the thickest layer of Sam’s model.

• mantle

• crust

• outer core

Multiple Choice

Sam is creating a computer model to present to his classmates so they can compare the properties of each layer of Earth.

The  ______  should be the thinnest layer of Sam’s model

• inner core

• mantle

• crust

• outer core

​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.

Fill in the Blank

The closer you get to Earth's core, the temperature __________.

​Explanation

• ​Temperatures increase as depth increases.

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