What BEST describes the mantle of Earth?

• a thin layer that is located on the surface
• a solid layer made of iron and nickel
• the largest layer between the crust and outer core
• the smallest layer that is made up of molten rock

Use the diagram to answer the question that follows. Which is the correct order of Earth’s layers, from outside to inside?

• crust, inner core, mantle, outer core
• crust, mantle, outer core, inner core
• mantle, crust, inner core, outer core
• inner core, crust, mantle, outer core

Which best compares Earth’s crust and mantle?

• The crust is thicker and less dense than the mantle.
• The crust is thinner and less dense than the mantle.
• The crust is thicker and more dense than the mantle.
• The crust is thinner and more dense than the mantle.

The inner core of Earth is solid because of the

• rate of rotation
• extreme temperature
• extreme pressure
• magnetic field

A difference between the oceanic crust and the continental crust is that the oceanic crust is

• composed chiefly of sedimentary rocks.
• more dense and thinner than the continental crust.
• older than the continental crust.
• continually being created

The picture below shows the layers of Earth. When compared to the other layers of the Earth, which layer has the lowest density?

• crust
• inner core
• mantle
• outer core

Which is the basic composition of Earth’s core?

• The solid inner core is surrounded by a liquid outer core.
• The liquid inner core is surrounded by a solid outer core.
• Both the inner core and the outer core are solid.
• Both the inner core and the outer core are liquid.

Earth's rotation around the core creates a dynamo effect. What is this responsible for creating?

• Earth's gravity
• Earth's atmosphere
• Earth's crust
• Earth's magnetic field
