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.

3. Edgar builds a model of Earth’s layers. His model is composed of two thin layers, that represent Earth’s crust and mantle.

4. 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 Edgar modify his model to accurately represent Earth’s layers?

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

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

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

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

The hot springs in this image are most likely heated by ________

Which correctly completes the sentence ?

• magma in the mantle; approximately 3,000 kilometers thick and is made mostly of iron, magnesium, and silicon. It is dense, hot, and semi-solid.

• 1. hot metals in Earth’s inner core; a solid metal ball with a radius of 1,220 kilometers. It is extremely dense and made mostly of iron and nickel.
