6.10 B Earth's Interior Layers Quiz

Look at the model of Earth’s interior. How would you label each of Earth’s layers, starting with the innermost layer of Earth and moving toward the outermost layer?

• Outer core; inner core; crust; mantle

• Crust; mantle; inner core; outer core

• Mantle; crust; outer core; inner core

• Inner core; outer core; mantle; crust

Mountains on Earth can be extremely tall, some reaching over 8 kilometers high. Which best describes the layer of Earth where mountains are found?

• Mountains are found in Earth’s mantle, which is the thickest layer of Earth with the most moderate temperatures.

• Mountains are found on Earth’s crust, which is the thickest layer of Earth with the coolest temperatures.

• Mountains are found on Earth’s mantle, which is the thinnest layer with an average temperature of 1000°C (1832°F).

• Mountains are found on Earth’s crust, which is the thinnest layer with the coolest temperatures.

Eduard builds a model of Earth’s layers. His model is composed of two thin layers, approximately 1.25 cm thick each, that represent Earth’s crust and mantle. It then has one thick layer, approximately 4 cm thick, to represent Earth’s outer core. Finally, it has a solid metal ball to represent Earth’s inner core. How should Eduard modify his model to accurately represent Earth’s layers?

• Eduard does not need to modify his model because it is already accurate.

• Eduard should make the layer that represents Earth’s crust thicker.

• Eduard should make the mantle thicker than all the other layers.

• Eduard should replace the solid metal ball with clay to better represent the inner core’s composition.

Evaluate the model of Earth’s layers to determine whether it is an accurate representation. Which corrections would you make and why?

• The model is correct as it is.

• The outer core should be labeled as solid.

• The inner core should be labeled as liquid.

• The middle of Earth should be labeled as the solid inner core, and the space around it as the liquid outer core.
