Mr. Fleming. The trapping of heat from the sun by gases in the Earth’s atmosphere. The major gas contributing to this process is Carbon dioxide gas.

1.  A greenhouse is a house surrounded by glass.  Greenhouses are used primarily for planting.  When the sun shines, the inside of the greenhouse becomes.

Global Warming  Global warming is the increase in the average temperature of the Earth's near- surface air and oceans.

The Greenhouse Effect. A greenhouse is a building used to grow plants when the outside temperature is too low. The roof of the greenhouse prevents convection.

Atmospheric gases allow sunshine to pass through but absorb heat that is radiated back from the surface of the earth. This acts as a blanket keeping heat.

Greenhouse Effect How we stay warm

The Sun’s energy reaches Earth through Radiation (heat traveling through Space)

Where: Near the Equator What is Insolation? The incoming solar radiation (energy from the Sun) that reaches Earth When and where does the most intense Insolation occur? Time of Day: Noon Time of Year: June 21 (NH) Where: Near the Equator

3 Main Greenhouse Gases: Greenhouse Effect The Process by which atmosphere gases absorb heat energy from the sun and prevent heat from leaving our atmosphere. In other words, greenhouse gases trap heat energy and keep it close to earth. 3 Main Greenhouse Gases: CARBON DIOXIDE (CO2), Methane, and WATER VAPOR

The Greenhouse Effect works like a Greenhouse Write your explanation and question in your notes

Is the Greenhouse Effect Good or Bad? It is necessary for life (good)- it keeps our climate toasty warm and prevents it from fluctuating (changing) too much. It is bad when: there are too many greenhouse gasses and the climate gets warmer (GLOBAL WARMING)

An increase in average global temperatures What is Global Warming? An increase in average global temperatures It is caused by an increase in Greenhouse Gases in the Atmosphere

Is Global Warming Happening? How much have global temperatures changed between 1980 and 2000? How much are global temperatures expected to change between 2000 and 2100?

Is Sea Level Rising? How much has sea level gone up since 1990?

Is Global Warming Causing Stronger Storms? Hurricanes get strength from warm ocean water. A warmer climate causes warmer ocean currents. We might see an increase in strong storms as a result of global warming.
