Did you think that the Greenhouse Effect is a bad thing?

• Yes

• No

as infrared, visible light, and ultraviolet light.

These are forms of Electromagnetic Energy and can be found in your ESRT on Page 14

​

​Solar energy travels to Earth...

​-Has wavelengths that are longer than red light.

-invisible

-Felt as heat

​​Infrared

-​All the colors you see in the rainbow

• ROYGBIV

​​Visible light

-Invisible

-Wavelengths shorter than violet

-Can cause sunburns, skin cancer, eye damage

​​Ultraviolet

Multiple Choice

This type of light is felt as heat.

• visible

• infrared

• ultraviolet

Multiple Choice

This type of light can cause sunburns, skin cancer, and eye damage.

• visible

• infrared

• ultraviolet

Multiple Choice

Why is Ultraviolet more harmful compared to the other types of Electromagnetic Energy entering our atmosphere?

• It has a longer wavelength

• It has a shorter wavelength

-Gases in the atmosphere trap heat. This forms a "blanket" around Earth.

-This is a natural process that helps temperature to stay consistent.

​What is the Greenhouse Effect?

Open Ended

What are the 2 major gases in our atmosphere (Troposphere)?

HINT: ESRT Page 1

Multiple Choice

Of the gases found in the Troposphere (ESRT Pg.1), which option most likely represents a Greenhouse Gas?

• Oxygen (O)

• Nitrogen (N)

• Other

Multiple Choice

Even though Greenhouse gases make-up less than 1% of our atmosphere, their effect is felt.

Which Greenhouse gas has a higher percentage than the others in our atmosphere?

• Methane

• Ozone

• Carbon Dioxide

• Nitrous Oxide

Multiple Choice

If greenhouse gases increase and build up in our atmosphere, what happens?

• They trap more heat and global temperatures rise.

• They trap more heat and global temperatures decrease.

• They trap less heat and global temperatures rise.

• They trap less heat and global temperatures decrease.

Multiple Choice

Which of these is NOT a greenhouse gases?

• Water Vapor (H₂O)

• Carbon Dioxide (CO₂)

• Methane (CH₄)

• oxygen (O)

Multiple Choice

Earth's atmosphere is like a greenhouse: sunlight enters the atmosphere and is trapped as:

• heat

• wind

• light

• energy

Multiple Choice

The earth absorbs sunlight as short wavelength energy (visible photons) and is heated when this energy is converted to longer wavelength energy. This (Longer Wavelength) heat that comes off earth's surface is called

• sunlight

• infrared radiation

• gamma radiation

• greenhouse gases

Multiple Choice

According to the diagram, what can happen when solar energy hits clouds in Earth's atmosphere?

• it can be reflected or absorbed

• it can only be absorbed

• it can only be reflected

• it is neither reflected nor absorbed

Multiple Choice

The energy form the sun that reaches the Earth is absorbed by _________________________.

• land and water

• underground water

• ice

• aliens

Multiple Choice

What type of land surface do you think will absorb radiation better?

• Dark Smooth Surfaces

• White Smooth Surfaces

• Dark Rough Surfaces

• White Rough Surfaces

Multiple Choice

Gases in the Earth's troposphere retaining the infrared radiation and warming the Earth is referred to as:

• Climate Change

• Permafrost Melt

• Ozone Depletion

• Greenhouse Effect

Multiple Choice

T/F: Water vapor is a greenhouse gas

• True
• False

Multiple Choice

T/F: Some greenhouse gases are naturally present in the Earth's atmosphere

• True
• False

Multiple Choice

Without the Greenhouse Effect the Earth would be

• warmer 

• colder

• temperature would not change

Multiple Choice

Which of the following is the best conclusion that can be made from this graph?

• atmospheric carbon dioxide levels have been decreasing since 1960
• Hawaii has a lot of carbon dioxide
• humans have been working hard to decrease carbon dioxide levels
• atmospheric carbon dioxide levels have increased steadily since 1960
