16.1
What causes night and day?
The rotation of the earth around its axis.
Seasons- caused by the tilt of the earth
Years- the time it takes for the earth to complete its revolution around the earth
This is the term for a tool that is used to make predictions about weather patterns in the future.
It is composed of programs that put together data regarding the atmosphere and oceans to stimulate climate.
Climate model
Name one of the effects of climate change.
Habitat change/changing landscape
migration
loss of ice
coral bleaching
changes in ocean acidity
economic losses
temp increase
increased risk of natural disasters
more heat related illnesses and death
stronger storms and more storm damage
wildlife at risk
What are the two ways that you can respond to climate change?
Adaptation and mitigation
Name 3 alternate sources of electricity
Nuclear power
Solar power
Wind power
Hydroelectric power
Geothermal power
How is weather different from climate?
Weather is short-term; climate is long-term.
This is the term for indirect types of evidence that give clues into past weather.
Proxy indicator
What does rising temperature do to the pH of the water?
Increases acidity, since carbon dioxide reacts with water to form carbonic acid.
What is the difference between adaptation and mitigation?
Adaptation- protecting people from the effects of climate change
Mitigation- reducing greenhouse gas emissions to reduce climate change
What agreement replaced the Kyoto protocol in 2016?
Paris Climate Agreement
These are three broad terms.
sun, wind, oceans
List one way that tree rings can give insight into past climate.
- The number of rings tells the number of years old a tree is, which could be matched to climate incidents at that year
- Wider rings indicate warmer, wetter weather
- Thinner rings indicate cooler, dryer weather
- Atypical growth (non-circular rings) indicate "corrective growth" for when a natural disaster may have happened
- Fire scars can indicate a forest fire
Rising sea levels threatens what communities the most?
Those living in coastal areas.
What sector the second largest source of greenhouse gas emissions?
transportation
What is carbon sequestration?
Carbon sequestration: Technology is used to trap and store carbon dioxide emissions.
Plants can take it in, carbon dioxide can be stored underground, react carbon dioxide with other compounds to store
What is latitude? How does it impact temperature?
Latitude= distance from the Equator
More latitude= cooler temperature (since the Equator is warm)
Ice can tell about weather since as ice forms, it could
- trap ________ or
- temperature changes can cause a different _____________.
trap gases, which can give insight into what gases and what concentrations of those gases were present in the atmosphere at that time
At different temperatures, ice has a different chemical composition (It is still H20, but its crystal structure is different at different temperatures)
Choose one of the following.
Birds
Polar Bears
Bugs
Koalas
Migration patterns change. They may come back earlier since spring is sooner and habitats are ready sooner.
Polar bears prey reduces, since hunting for seals is more difficult with melting ice since they have to swim farther
Some bugs thrive in the warmer weather and actually grow more.
Koalas food supply goes down, as the changing temperatures changes the chemical composition of eucalyptus leaves making them inedible for koalas
What percent of gasoline is actually used towards moving the car forward?
14%
What are three alternatives to fuel-only cars?
-Hybrid
- biofuels
- electrofuels
-electricity
-hydrogen fuel cells
What are the two principles behind thermohaline circulation?
Cold water is denser than warm water AND saltier water is denser than less saltier water.
These differences in density allow for circulation of water and nutrients in the oceans.
- Plant remains, organism remains tell what plants lived during that time which can give information into the climate that was required to support those plants
- dust and particle accumulation tell about erosion patterns
- element composition tells of temperature changes
What is coral bleaching?
When rising temperatures increases ocean acidity and algae are killed or kicked off of coral, corals lose their color and may also die since they need algae to survive
What is cap and trade?
Cap-and-Trade: System of emission
allowances that can be sold or traded, gives companies incentive to reduce emissions
What is a carbon footprint?
Carbon footprint: The amount of carbon dioxide for which an individual or group is responsible
