An increase in carbon dioxide in the atmosphere is associated with an increase in global temperature. Which property of carbon dioxide is responsible for this temperature increase?

• A.Carbon dioxide transmits more sunlight than other atmospheric gases. 
• Carbon dioxide efficiently turns sunlight into heat
• Carbon dioxide keeps heat in the atmosphere from escaping    into space
• Carbon dioxide stores solar energy in chemical bonds. 

How is the stratosphere different from the troposphere?

• The clouds in the stratosphere produce more rain.
• The air in the stratosphere has a greater density.
• The composition of the stratosphere lacks ozone.
• The temperature of the stratosphere warms at higher altitude.

Why does the troposphere experience the greatest amount of atmospheric pressure compared to the other atmospheric layers?

• It produces the ozone layer.
• It has the highest temperatures.
• It contains a high concentration of gas particles.
•  It is the region in which weather occurs.

In which layer of Earth’s atmosphere does weather occur?

• mesosphere
• stratosphere
• thermosphere
• troposphere

One substance found on Earth is more stable as an elemental gas than as part of a solid compound. As a result, this substance is very abundant in the atmosphere. Which substance exhibits these traits?

• Argon
• Chlorine
• Nitrogen
• Oxygen 

An atmospheric layer of a specific gas provides shielding from harmful ultraviolet light from
the Sun, allowing life to thrive on Earth. What gas makes up this layer?

• Water
• Carbon Dioxide
• Nitrogen 
• Ozone 

Some jet airplanes fly in a layer of the atmosphere where temperature generally increases with altitude. What is this layer of the atmosphere?

• Mesosphere
• Stratosphere
• Thermosphere
• Troposphere

What instrument should be used to monitor atmospheric pressure changes as a weather
system approaches?

• psychrometer
• thermometer
• anemometer
• barometer 

What gas does wedge X represent?
