The Greenhouse Effect

The most abundant gas in the atmosphere is

• oxygen

• nitrogen

• carbon dioxide

• argon

The the second most abundant gas in the atmosphere is

• oxygen

• nitrogen

• carbon dioxide

• argon

Which of the following does NOT happen to solar energy when it reaches Earth?

• Some solar energy reflects off the atmosphere, back to space

• Some solar energy passes through Earth and comes out the other side

• Some solar energy is absorbed by land and water

• Some solar energy is re-radiated from the Earth's surface as infrared energy and trapped by the atmosphere

The greenhouse effect is caused by...

• increased output of solar radiation reaching Earth

• the Earth releasing more infrared radiation (heat) at night

• gases in the air trapping infrared radiation (heat) released by the Earth

• a hole in the ozone layer that allows harmful solar radiation to reach Earth's surface

The greenhouse effect is a natural process

• true

• false

Without the Greenhouse Effect the Earth would be

• warmer

• colder

Which of the following are greenhouse gases?

• Carbon dioxide

• Methane

• Water vapor

• All of the Above

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

• Temperature goes up
• Temperature goes down

The area of human activity responsible for the highest greenhouse gas emissions is

• agriculture

• industry

The area of human activity responsible for the second highest greenhouse gas emissions is

• residential activity

• transport

• agriculture

• industry
