The Greenhouse Effect

The Greenhouse Effect

​The Green House Effect

​Describe the green house effect and how it affects the earth

What is the greenhouse effect?

• Sun produces solar radiation

• Some is reflected back into space by Earth's atmosphere

• Some passes through atmosphere & is absorbed by Earth's surface

• More greenhouse gases released 🢂 Greater gas layer & more thermal energy absorbed

• Greenhouse gases consist of carbon dioxide, methane, ozone, nitrous oxide, chlorofluorocarbons, and water vapor

​Are the green houses gases important in the atmosphere?

​Too much green houses gases leads to global warming.

Multiple Select

Select ALL examples of greenhouse gases from the list below.

• water vapor (H₂O)

• oxygen (O₂)

• methane (CH₄)

• carbon dioxide (CO₂)

Multiple Choice

Burning fossil fuel (coal & oil) releases _____ into Earth's atmosphere.

• water vapor (H₂O)

• oxygen (O₂)

• methane (CH₄)

• carbon dioxide (CO₂)

Multiple Choice

Green House gases

• absorb the sun's radiation and trap heat

• are good for our health

• absorb gravity and keep us attached to Earth

• expulse radiation to the sun and prevent us from getting to warm

Multiple Choice

What would be Earth's temperature without green house gases?

• Earth's temperatures would be cold, oceans would freeze

• The same, green house gases do not affect Earth's temperature

• Earth's temperature would be 90 Fahrenheit

Multiple Choice

What activity is increasing green house gases?

• Ocean and air currents

• Volcanic activity

• Plants activity

• Human activity

Multiple Choice

what is greenhouse effect

• the process of reflecting the heat from the back to the outer space.

• it is the process of trapping of heat from the sun by the greenhouse gases.

Multiple Choice

True or False: All of the radiation from the Sun is absorbed by the Earth

• True
• False

Multiple Choice

Without the Greenhouse Effect the Earth would be

• warm 
• cold
• dead

Multiple Choice

How would Earth be different without greenhouse gases in its atmosphere?

• More heat from solar radiation would escape into space

• More solar radiation would be reflected back into space

• More solar radiatio would penetrate Earth's crust and mantle

• More heat from solar radiation would be stored in Earth's crust

Multiple Choice

About 30% of the sun's incoming energy never reaches Earth because it is....

• absorbed by the ocean
• trapped by the gravitational pull between the moon and the Earth 
• reflected back into space
• destroyed by the ozone layer

Multiple Choice

Greenhouse gases, in moderate amounts, keep the Earth's temperature stable

• True
• False

Multiple Choice

What gas is known for increasing the amount of "trapped" heat in the atmosphere?

• Oxygen

• Nitrogen

• Methane

• Carbon Dioxide

Multiple Choice

Things you can do to help decrease global warming include:

Multiple Choice

 Why is the increase of Greenhouse gasses a big issue?

• It causes climate change and increase in the global temperature 

• It leads to more factories

• It causes a major decrease in people
