Section 8-11: Studying Clues to Past Climates

Exercise 1
Step 1
1 of 3
a) Many scenes depicted icy landscapes
Step 2
2 of 3
b) paintings are proxy records since they only visually depict surroundings while the temperature and patterns throughout the years would be direct records.
Result
3 of 3
a) Many scenes depicted icy landscapes
Exercise 2
Step 1
1 of 4
a) Scientists create tables and graphs to show temperature and precipitation trends to view the overall climate and how it changes
Step 2
2 of 4
b) Scientists use rocks and other landscapes features and markings to predict what the climate was like to create such features as well as how animals may have evolved to live in certain regions due to its climate
Step 3
3 of 4
c) The do not know that they are entirely accurate, but their models are created to be as accurate as possible
Result
4 of 4
a) Scientists create tables and graphs to show temperature and precipitation trends to view the overall climate and how it changes
Exercise 3
Result
1 of 1
You could source weather records, paintings, and news articles
Exercise 4
Step 1
1 of 4
a) ice cores allow us to determine the amount of greenhouse gas present within the atmosphere during a certain time period
Step 2
2 of 4
b) tree rings can show precipitation patterns and scarring from fire
Step 3
3 of 4
c) By analyzing the chemicals in the ocean floor sediment the ocean currents can be interpreted which helps us predict how the ocean currents affected the surface temperature and air which affects land mass climates
Result
4 of 4
a) ice cores allow us to determine the amount of greenhouse gas present within the atmosphere during a certain time period
Exercise 5
Result
1 of 1
They cannot directly determine temperature, but they can determine amounts of greenhouse gas present, which would help them predict temperature
Exercise 6
Step 1
1 of 3
Ice cores and tree rings are the most likely proxy records for dating back so far
Step 2
2 of 3
They can release their studies and findings for analysis and confirmation from other climatologists around the world
Result
3 of 3
Ice cores and tree rings are the most likely proxy records for dating back so far
Exercise 7
Result
1 of 1
Depending on where the fossil is found we can determine how the climate was based on the features of the organism that was fossilized
