Greenhouse and Radiation

Which of the following is NOT a greenhouse gas?

• Carbon dioxide

• Methane

• Water vapor

• nitrogen

What happens to the temperature if more greenhouse gases are released into the atmosphere?

• Temperature goes up
• Temperature goes down

Without the Greenhouse Effect the Earth would be

• warm 
• cold
• dead

1.  Certain gases in the atmosphere – water vapor, carbon dioxide, methane and nitrous oxide – help maintain the Earth’s temperatures and climate. These are called: __________ . 

• A.  ozone gases
• A.  solar gases
• A.  greenhouse gases 
• A.  stomach gases

1.  Why is the Ozone important to life on Earth?

• A.   The Ozone reflects all the Ultra Violet radiation
• A.  The Ozone absorbs all the heat that come up from the Earth.
• The Ozone provides all the oxygen to Earth.
• The Ozone protects the Earth’ s atmosphere and the life on Earth from harmful radiant energy emitted by the sun   

 Which of the following activities contributes the most to carbon emissions globally?

• Deforestation
• Agriculture
• Burning fossil fuels
• Respiration

The greenhouse effect is caused by

• more heat arriving at the Earth from the sun

• the Earth releasing more heat at night

• gases in the air trapping heat released by the Earth

The graph shows us that

• the earth temperature is always increasing

• the earth's temperature has steadily increased since 1900

• the earth's temperature has steadily rising since the 1960s

• the earth's temperature decreased during the 19th and 20th centuries

The greenhouse effect comes from

• all heat being released by the earth going back into space

• some of the heat heat being released by the earth going back into space

• some of heat being released by the earth being trapped in the air

• all of heat being released by the earth being trapped in the air

What are the two most common greenhouse gases?

• Water Vapor (H₂O) and Methane (CH₄)
• Carbon Dioxide CO₂ and Methane (CH₄)
• Water Vapor (H₂O) and Carbon Dioxide CO₂
• Water Vapor (H₂O) and Nitrous oxide (N₂O)
