Earth's Interior

Study the diagram showing the range of temperature in the Earth's layers. What does the diagram show about Earth's interior?

The continental crust is the coolest region.

Study the images of Earth's crust and mantle in two different areas. How is Item A different from Item B?

The crust in Item A is found partially below sea level as compared to the crust in Item B.

A scientist collects a core sample from 60 km deep in Earth. Which characteristic will she most likely observe in this sample?

The sample mainly consists of granite.

Which region of Earth's crust experiences the least amount of pressure?

crust

Which objects can an S wave travel through? Check all that apply.

crust granite soil

Which layers most likely have a pressure, represented in units of GPa, ranging from 75 GPa to 110 GPa? Check all that apply.

lithosphere oceanic crust asthenosphere

Study the diagram about the varying pressures of Earth's Layers.

110 GPa

Study the image of a seismic graph. About how far does the S wave travel through Earth in 13 minutes?

4,000 km

Which statement describes a characteristic of the asthenosphere?

Pressure is higher than crust.

Which statement correctly compares the thicknesses of Earth's layers?

Earth's lithosphere is thinner than its asthenosphere.

Why is Earth's outer core hotter than Earth's oceanic crust?

Earth's outer core is deeper within Earth than oceanic crust is.

Which statement describes how the mantle is similar to Earth's oceanic crust?

It has varying degrees of thickness.

Study the graph about seismic waves. What does the graph show?

The P wave travels through Earth's crust more quickly than the S wave travels.

Which statement describes a difference between the lower mantle and oceanic crust?

The lower mantle experiences more pressure than oceanic crust does.
