The Atmosphere

Which two layers of the atmosphere are characterized by decreasing temperatures with increasing altitude?

• troposphere, mesosphere

• stratosphere, mesosphere

• stratosphere, thermosphere

• troposphere, thermosphere

Where does most of Earth's weather occur?

• mesosphere

• stratosphere

• troposphere

• thermosphere

What is the correct sequence of layers of the atmosphere from innermost to outermost?

• thermosphere-mesosphere-stratosphere-troposphere

• stratosphere-thermosphere-troposphere-mesosphere

• mesosphere-stratosphere-thermosphere-troposphere

• troposphere-stratosphere-mesosphere-thermosphere

What is the composition of the troposphere?

• The troposphere contains 75% of the ozone in the atmosphere and very little water vapor.

• The troposphere contains 75% of the iron in the atmosphere because meteors heat up and break apart in this layer.

• The troposphere contains 75% of the mass of the atmosphere and nearly all of its water vapor.

• The troposphere contains 75% of the charged particles in the atmosphere because they form when energy hits atoms in this layer.

Which of the following is stratospheric ozone NOT responsible for?

• screening out ultraviolet radiation

• preventing ozone formation in the troposphere

• helping protect humans from sunburn and cataracts

• lowering atmospheric water vapor

Which statement best explains how the gases of the atmosphere affect the temperature of Earth?

• The gases reflect some of the heat from Earth's surface, holding it away from the surface in space.

• The gases absorb some of the heat from the Sun, holding it to keep it warm near Earth's surface.

• The gases absorb all of the heat from Earth's surface, preventing it from radiating into space.

• The gases reflect all of the heat from the Sun, preventing it from reaching Earth's surface.

Cecilia is making a poster for a science class presentation. She is presenting on a layer of the atmosphere. She is writing down facts to include on her poster. The facts Cecilia has included are shown:

• Highest temperatures in the atmosphere

• Contains most of the ionosphere

• Contains less that 0.001% of atmospheric gas

• Located above the mesopause

What layer of the atmosphere is Cecilia presenting on?

• the troposphere

• the thermosphere

• the mesosphere

• the stratosphere

The graph shows the relationship between altitude and atmospheric pressure.

In which layer of the atmosphere is air pressure the lowest?

• the thermosphere

• the stratosphere

• the mesosphere

• the troposphere

Chantal is creating a diagram showing the layers of Earth's atmosphere.

She wants to show the location of the ozone layer on her diagram.

Where should Chantal place the label for the ozone layer?

• the mesosphere

• the stratosphere

• the troposphere

• the thermosphere

Which of the following is NOT a protection provided by the layers of Earth's atmosphere?

• the reduction of the Sun's harmful rays reaching living organisms on Earth

• the maintenance of a stable temperature suitable for life on Earth

• the creation of seasons that allow temperature changes on Earth

• the burning of objects from space before they reach the surface of Earth
