Quiz on Friday
What to Study
1) Know percentages of O2 and N2 in Earth’s atmosphere.
2) What is ozone, where is it found, what type of radiation does it protect
us from, and how is it being destroyed?
3) Be able to draw and describe Greenhouse Effect in terms of types of
radiation entering (short wavelength) and type of radiation trapped to
heat planet (long wavelength infrared;heat)
4) Name types of em radiation from most harmful to least.
gamma, xray, ultraviolet, visible, infrared, microwave, radiowaves
5) How does nitrogen get into our food chain? (bacteria on bean roots “fix”
it into soil from atmosphere and lightening fixes it into soil) Plants absorb
nitrogen through roots use it to make proteins for growth and repair.
Animals eat plants etc…..
1= Nitrogen introduced into soil by lightening and precipitation depositing it.
2= Nitrogen gets into the soil by way of fertilizer also (not shown) bacteria
living on roots of beans and clover can pull N2 out of atmosphere and
“fix” it into soil
3= Plants make proteins for growth and repair using nitrogen from soil
4= Animals like cows eat plants, take in nitrogen, and use it to build protein
for growth and repair
5/6 = When animals die or excrete waste, nitrogen is returned to soil.
Decomposers like bacteria help to return the nitrogen to the soil and
into the air
7= Once nitrogen is back in the air, the cycle continues
6) How does Carbon cycle through the atmosphere?
Combustion or burning
wood, fuel etc…. gives
off CO2.
Green plants absorb
CO2 out of
atmosphere during
photosynthesis and use
it to produce sugar
(C6H12O6) and in the
process give off
Oxygen needed by animals to do cell respiration.
Animals do cell respiration to turn sugar into energy. In the process they
absorb the oxygen made by plants and release carbon dioxide into the
atmosphere (through breathing).
Waste and dead organic material (once living) return carbon to soil and
atmosphere as bacteria act to decay it.
7) What is global warming and what causes it?
8) What is the Goldilocks Effect?
9) Be able to compare Mars and Venus atmospheres to Earth’s atmosphere.
10) Name the 4 main layers of the atmosphere.
11) Be able to describe the temperature changes within each layer of the
atmosphere.
12) Know what happens in each layer of the atmosphere ( weather
troposphere, ozone stratosphere, meteors burned up mesosphere,
thermosphere northern lights….)
13) Be able to describe what air pressure is , how we measure it, how it
changes with changing altitude
