Why is the increase of Greenhouse gasses a big issue?

• It causes climate change and increase in the global temerature 
• It can lead to a major increase in Greenhouses 
• It leads to more factories
• It causes a major decrease in people

 What is the greenhouse effect?

• The warming of a planet due to trapped radiation.
• The cooling of Earth due to air pollution.
• The heating of a solid, such as a rock.

• Urethane
• Oxygen
• Carbon Dioxide

Which one of the choices below is NOT a  cause for global warming?

The gradual increase in the temperature of the atmosphere is known as ________________.

• Greenhouse Effect

• Carbon Dioxide Gases
• Methane

Without the "greenhouse effect"

• Overnight temperatures would plunge downward
• the earth would catch on fire
• the earthe would heat up drastically
• the atmosphere would leave

What do greenhouse gases do?

• absorb Earth's outgoing infrared photons
• reflect Earth's incoming infrared photons
• magnify ultraviolet radiation in the atmosphere
• block the Sun's infrared radiation

Surface currents...

• Warmer and are created by wind
• Warmer and are more dense than deep ocean currents
• Cooler and more dense than deep ocean currents
• Cooler and are created by wind
