Using land for farms and cities
This graph shows that
Earth's temperature has maintained a cyclical pattern, warming approx every 100,000 years
Earth's temperature has always been warmer than the present
Earth's temperature has always been colder than the present
Earth's temperature has changed randomly throughout history
Changes in eccentricity will have what effect on the global temperature?
Determines which hemisphere has stronger seasons from eccentricity
More gives Earth stronger seasons
(warmer summer, colder winter)
Oval gives one hemisphere stronger seasons (the other is more mild)
Precession is_________
The tilt is changing
The orbit is more oval or more circular
The pole wobbles like a top about to fall.
This graph, similar to one in your packet, shows the that___________
There is a direct relationship between temperature and greenhouse gases
Greenhouse gases have no effect on the temperature
Greenhouse gases today are lower than they have been in the past
we don't have any data of the temperature or gases from thousands of years ago
What does this graph show?
The temperature has decreased over the last 100 years
The temperature has increased by about 0.5 degree C
The temperature has not changed since 1900
The temperature has increased by a little over 1 degree C in the last 100 years
The current warming trend is mostly due to ________ causes
Natural
Anthropogenic
Alien
How does the ocean become more acidic?
The ocean absorbs more carbon dioxide released by the burning of fossil fuels
Boats are dumping toxic waste into the ocean
The fish are not able to neutralize the acid in the ocean
The ocean is actually becoming more basic
In the ocean acidification lab, what happened?
We exhaled carbon dioxide into the water, the indicator turned BLUE, showing that the pH INCREASED
We exhaled carbon dioxide into the water, the indicator turned YELLOW, showing that the pH DECREASED
The water bubbled because of the presence of acid, turning the water blue
We removed the oxygen in the water, causing it to become more acidic
What happens to the ocean ecosystem when the pH level decreases?
The plankton and krill become damaged, disrupting a major food source
The blood chemistry of the predators is affected
The producers in the ocean increase
Ozone in the ______________ protects us from _________
stratopshere; UV rays
troposphere; UV rays
stratosphere; CFCs
troposphere; smog
Ozone pollution in the _____________ is a major component of _________
stratosphere; UV rays
troposphere; smog
stratosphere; the hole in the ozone layer
troposphere; global warming
Which part of the CFC molecule breaks off to destroy ozone?
carbon
chlorine
fluorine
oxygen
Changes in obliquity or TILT will have what effect on the global temperature?
Determines which hemisphere has stronger seasons from eccentricity
More gives Earth stronger seasons
(warmer summer, colder winter)
Oval gives one hemisphere stronger seasons (the other is more mild)
6O2 + C6H12O6 -> 6CO2 + 6H2O + Energy
CH4 + 2O2 + -> CO2 + 2H2O
6CO2 + 6H2O -> 6O2 + C6H12O6 + Energy
O2 + 2H2 -> 2H2O
Photosynthesis makes glucose or ______ for the organism, while Cellular Respiration makes ATP or ___________
food; cell energy
cell energy; food
carbon dioxide; sunlight
sunlight; oxygen
What is the correct equation for combustion?
6O2 + C6H12O6 -> 6CO2 + 6H2O + Energy
CH4 + 2O2 + -> CO2 + 2H2O
6CO2 + 6H2O -> 6O2 + C6H12O6 + Energy
O2 + 2H2 -> 2H2O
Which is NOT an effect of Global Warming?
