Review: Greenhouse Effect and Carbon

Greenhouse Effect

Honors Earth & Energy Essentials

Energy IN

=

Energy OUT

Electromagnetic energy travels in waves by radiation through space to Earth

Multiple Choice

The range of wavelengths of solar radiation (including infrared, visible light, and ultraviolet) is known as

• Earth's energy budget

• solar flares

• the greenhouse effect

• the electromagnetic spectrum

Electromagnetic Spectrum

Type of Energy that Travels in waves, such as LIGHT and HEAT

Earth's Energy Budget

• Sun sends sends electromagnetic energy to Earth via radiation through space

• Energy enters Earth atmosphere as short wave (visible light)

• Energy can can be absorbed, reflected, scattered by atmosphere, clouds, Earth's surfaces (land, water, ice)

• Absorbed energy is then converted and reflected back as longer wave, infrared energy

• Nature's goal is to keep a balanced process

Multiple Choice

The wavelengths of electromagnetic energy that can be seen by humans is known as

• ultrared radiation

• visible light

• ultraviolet radiation

• infrared radiation

Multiple Choice

Which wavelength is longest?

• A

• B

• C

• D

Multiple Choice

Infrared Light is

• the light you can see from the sun

• this is where most of the warmth that you feel from the sun comes from

• higher-energy radiation that can harm life

Multiple Choice

Which type of solar energy has the longest wavelength?

• ultraviolet radiation

• they all have the same wavelengths

• visible light

• infrared radiation

Multiple Choice

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

• land and water

• underground water

• ice

• aliens

Multiple Choice

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

• True
• False

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

In the diagram, which arrow(s) represents the warming that's caused by the greenhouse effect?

• 1 and 3

• 2

• 4 and 6

• 5

• 7

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 heat that comes off earth's surface is called

• sunlight

• infrared radiation

• gamma radiation

• greenhouse gases

Multiple Choice

The greenhouse effect is:

• an unnatural phenomenon that has no beneficial purpose

• a natural phenomenon that decreases surface temperatures

• a natural phenomenon that is important for making Earth habitable, but too much can be bad

• none of the above

Multiple Choice

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

• heat

• wind

• light

• energy

Multiple Choice

Which of these is NOT a greenhouse gases?

• ozone

• carbon dioxide

• methane

• oxygen

Multiple Choice

Which of the following molecular shapes has the potential to be a greenhouse gas?

Multiple Choice

Factors that affect the impact of greenhouse gases.

• Sunlight has short wavelength radiation, and these gases absorb only long wavelength radiation.

• Sunlight has long wavelength radiation, and these gases absorb only short wavelength radiation.

HUMAN IMPACT

Multiple Choice

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 radiated from the Earth's surface and trapped by the atmosphere

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

TRUE or FALSE: Based on your simulation and the impact of clouds, SMOG from human factors like air pollutants, can also lead to increase surface temperatures.

• TRUE

• FALSE

Multiple Choice

Without the Greenhouse Effect the Earth would be

• warm 
• cold
• dead

Let's also review a few carbon cycle questions since carbon in the atmosphere is super relevant!

Multiple Choice

Where can you find carbon?

• Only in the Earth's atmosphere.

• Inside all water molecules.

• True

• False

Multiple Choice

Which of the following natural events is NOT a source of carbon dioxide?

• Wildfire

• Decomposing plants and animals
