LT 10-3

I can describe the connection between different types of electromagnetic radiation and their energies

Multiple Choice

What form of electromagnetic radiation listed below has the lowest amount of energy associated with it.

• Ultraviolet (UV)

• Visible Light

• Infrared (IR)

Multiple Choice

What form of electromagnetic radiation listed below has the highest amount of energy associated with it.

• Ultraviolet (UV)

• Visible Light

• Infrared (IR)

LT 10-4 I can describe changes that occur when electromagnetic radiation is abosbed and emitted by matter.

Multiple Choice

What kind of light can pass through our atmosphere?

• Ultraviolet (UV)

• Infrared (IR)

Multiple Choice

When the Ultraviolet (UV) light hits the earth the following occurs.

• All of it is reflected

• All of it is absorbed

• Some is reflected and some is absorbed

Multiple Choice

What happens to the Ultraviolet light that is absorbed by the earth?

• All is reemmitted as UV light again

• All is reemitted as Infrared Light (IR)

• All is stored in the earths surface

• Some is reemitted as Infrared Light (IR) and some is stored in earths surface.

Multiple Choice

What kind of light is trapped by greenhouse gasses in our atmosphere?

• Ultraviolet (UV)

• Infrared (IR)

Multiple Choice

How do the bonds in greenhouse gasses trap energy in our atmosphere?

• The bonds are not affected by greenhouse gasses

• The bonds absorb and reflect Ultraviolet (UV) light.

• The bonds absorb and reflect Infrared (IR) light.

• The bonds absorb energy and store it in the atmosphere

Multiple Choice

What do all Greenhouse gass molecules have in common?

• They are the most abundant in the atmosphere

• They are made of three or more atoms

• Once in the atmosphere they can never leave

• They interact with ultraviolet (UV) light.

LT 10-5

I understand how differenet substances absorbe electromagnetic radiation, and how this leads to differences in earth's albedo.

Multiple Choice

Which type of surfaces will have higher Albedo (reflectivy)?

• Dark surfaces

• Light surfaces

Multiple Choice

If all the asphalt on earth was replaced with grass. Based on albedo would this increase or decrease global temperatures?

• Increase

• Decrease

Multiple Choice

If polar icecaps melted exposing more ocean. Based on albedo would this increase or decrease global temperatures?

• Increase

• Decrease

Multiple Choice

Many cities are replacing tar roofs with green planted roofs. How will this affect the temperatures in these cities?

• Increase

• Decrease

LT 10-6

I can describe how changes in atmospheric carbon will impact the carbon cycle and other Earth systems.

Multiple Choice

In the spring the level of CO2 in the atmopshere will...

• Increase plants are more active

• Decrease as photosynthesis increases

• Increase as fossil fuel emmissions have not changed

• Decrease as people use more airconditioning

Multiple Choice

Based on the data on the graph which statement about CO₂ levels is accurate

• The amount of CO₂ in the atmosphere did not fluctuated prior to human impacts.

• The amount current of CO₂ in the atmosphere is similar to past changes in CO₂ Levels.

• The amount of CO₂ in the atmosphere has had a steady and consistant increase over the past 800,000 years.

• Since 1800, the amount and rate of increase in CO₂ levels has exceeded all past observations.

LT 10-7

I can analzye data on carbon sources to determine the effect of chanign amounts on Earth's systems.

Multiple Choice

Based on this graphic, where thin arrows represent natural carbon cycle processes and thick arrow respresent human impacts, without humans - how would the carbon in the atmphere change from year to year?

• increase each year

• decrease each year

• stay the same

• not enough information to telll.

Multiple Select

Based on this graphic, how may Gigitons of Carbon are added to the atmosphere each year from the use of fossil fuels?

• 1.5

• 2.5

• 4.9

• 9.5

Multiple Choice

All of the 9.5 Gt of Carbon added to the atmosphere by burning fossil fuels stays in the atmosphere.

• True, each year the total carbon in the atsmosphere increases by 9.5 Gt

• True, the oceans and plants can only take in as much carbon as they put out.

• False, while the oceans and plants can remove some of the additional carbon from the atmosphere, about 4.9 Gt will remain in the atmosphere

• False, becuase carbon moves through the atmosphere in a cycle, what is added is removed each year.

Multiple Choice

On the graphs to the right black shows current trends and blue is what would happen if humans stopped emmiting CO_2.. According to the graph on the right, If humans stopped emmiting all CO₂, then he amount of CO₂ in the atmosphere would

• decrease

• increase

• stay the same

Multiple Choice

On the graphs to the right black shows current trends and blue is what would happen if humans redced CO₂ emmissions by 50%. According to the graph on the right, If humans reduced emmissions of CO₂, then the amount of CO₂ in the atmosphere would...
