#2 |
Define climate change |
change in weather patterns over a long period of time |
#3 |
How many degrees has the temperature risen in the last 100 years? |
1 degree |
#4 |
Define global warming. |
an average increase in Earth's surface temperature |
#5 |
Explain why a SMALL change in temperature can make a big difference. Name two changes that could occur. |
sea levels will rise, hurricanes will become stronger and more intense, glaciers will melt, more droughts and heatwaves |
Evidence of Climate Change |
#1 |
What does a paleoclimatologist study? |
past climate changes |
#2 |
Explain what a proxie is. |
They are examples of evidence showing changes in the climate and greenhouse gasses |
#3 |
Why do scientists want to find out information about how the Earth's climate changed during the past? |
It will give them a prediction of future events |
#4 |
Name two proxies of climate change |
ice core samples, tree rings, coral samples,sedimentary rock samples, sediment layers |
#5 |
How do scientists know the amounts of greenhouse gasses in the atmosphere at certain times during the past? |
they study air bubbles trapped in ice samples |
Mystery |
#1 |
True or False: All cars are fueled by petroleum |
false |
#2 |
How can a car be more fuel efficient? |
use the AC less, buy smaller compact cars that get good gas milage |
#3 |
Describe a type of car that would cause a greater amount of damage to the environment. |
Large SUV or Trucks with low gas milage |
#4 |
What are steam engines fueled by? |
burning coal |
#5 |
Explain how farming affects the environment since it became modernized? |
The same amount of land was used, but the machines used now add to burning fossil fuels and increasing temperatures |
Human Influenced Factors |
#1 |
In the past, was climate change a natural event or human caused? |
occured naturally in the past |
#2 |
Which is more environmentaly friendly, using a train or truck to transport goods? |
train |
#3 |
Explain how population growth leads to climate change. |
More people means more cities, more homes and more heating and cooling needs, more fossil fuels will be burnt, more transportation and vehicles will be needed |
#4 |
Name three activities people do in their daily lives that lead to climate change. |
driving cars. electricity, heating and cooling homes and buildings, building cities, farming, water heating, cooking, waching clothes |
#5 |
Explain why deforestation is believed to be causing Earth's climate to change. |
trees absord carbon dioxide. If the trees are cut down, then there is nothing to absord the carbon and the gasses get released into the atmosphere |
