Multiple Choice

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.

Multiple Choice

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.
