Which of the following is NOT one of the four major spheres of Earth ?

• A. Lithosphere

• B. Biosphere

• C. Hydrosphere

• D. Atmosphere

The Earth's crust is described as:

• Thickest under the oceans and thinnest under the continents

• A solid sphere of iron and nickel at Earth's center

• The thin, rigid outermost layer of Earth

• The layer responsible for aurora lights

The oceanic crust is generally:

• Thicker than continental crust

• Thinner than continental crust

• The same thickness as continental crust

• Found only in mountain regions

The mantle is the layer beneath the crust. Which statement correctly describes it?

• It is Earth’s thinnest layer, only a few miles thick

• It extends to about 2,900 kilometers in depth and is the thickest layer

• It is made of liquid iron and nickel

• It forms the outermost rigid surface of Earth

The outer core of Earth is unique because:

• It is completely solid iron and nickel

• It is the only liquid layer of the Earth

• It contains all of Earth’s groundwater

• It extends only a few kilometers below the crust

The inner core differs from the outer core because it is:

• A. A liquid layer that supports plate movement

• B. A solid sphere of iron and nickel at Earth’s center

• C. A zone where convection currents occur

• D. Composed entirely of oxygen and nitrogen gases

The atmosphere is best described as:

• A. A solid shell surrounding the planet

• B. Layers of gases such as nitrogen and oxygen surrounding Earth

• C. The zone containing Earth’s water in oceans, rivers, and glaciers

• D. The rigid layer where tectonic plates float

Which atmospheric layer do we live in?

• Stratosphere

• Troposphere

• Mesosphere

• Exosphere
