Study the graph about seismic waves.

What does the graph show?

• The S and P waves travel the same distance through Earth’s crust in the same amount of time.

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

• It takes the P wave 18 minutes to travel 6,000 km through Earth’s crust.

• It takes the S wave 11 minutes to travel 8,000 km through Earth’s crust.

Study the image of Earth’s layers.

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

• Earth’s mantle is thinner than its oceanic crust.

• Earth’s outer core is thicker than its mantle.

• Earth’s continental crust is thicker than its lithosphere.

• Earth’s lithosphere is thinner than its asthenosphere.

A scientist collects a core sample from 60 km deep in Earth.

Which characteristic will she most likely observe in this sample?

• The sample has high iron content.

• The sample is very hot and liquefied.

• The sample mainly consists of granite.

• The sample has a very high density.

Study the table about Earth’s interior.

If silicic rock is found in a core sample, what evidence does this provide about the rock’s location?

• Its location is likely underneath an ocean or a mountain.

• Its location is likely denser than Earth’s lithosphere.

• Its location likely has a consistency that changes from solid to liquid.

• Its location likely contributes to the creation of Earth’s magnetic field.

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

• crust

• mantle

• outer core

• inner core

Study the diagram showing the range of temperature in the Earth’s layers.

What does the diagram show about Earth’s interior?

• The outer core is the hottest region.

• The mantle is hotter than the outer core.

• The continental crust is the coolest region.

• The inner core is cooler than the lithosphere.

Which statement describes a characteristic of the asthenosphere?

• Temperatures are cool.

• Consistency is solid.

• Thickness is less than crust.

• Pressure is higher than crust.

Study the images of Earth’s crust and mantle in two different areas.

How is Item A different from Item B?

• The crust under the ocean in Item A is thicker than the crust under the mountain in Item B.

• The mantle under the ocean in Item A is thinner than the mantle under the mountain in Item B.

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

• The mantle in Item A is located far below a mountain as compared to the mantle in Item B.
