proxy data

Paleoclimatologists can use historical data to study temperature and precipitation trends of the past. These observations can be found in all of the following EXCEPT...

• Farmers logs
• Newspaper accounts
• Your local TV news
• Travellers' Diaries

Paleoclimatologists can use corals to study the climate of the past. By looking at oxygen isotope ratios they can determine the ___________ of that time period.

• Precipitation
• Temperature 
• Barometric Pressure
• Humidity

Paleoclimatologists can use fossilized pollen to study the climate of the past. Once the fossil is dated they can determine what kind of plants lived at that time. From that they can start to determine the ______________ of that time period. 

• Dew Point
• Temperature 
• Barometric Pressure
• Humidity

Paleoclimatologists can use ice cores to study the climate of the past. Ice cores allow them to get samples of the atmosphere of the past, as well as determine the temperature of the climate in the past. They do this by looking at all of the following EXCEPT... 

• Air Bubbles
• Oxygen Isotopes
• Dust
• Crystal structure

Paleoclimatologists can use tree rings to study the climate of the past. The size of the ring can help them determine the ________________ of the year the ring represents. 

• Precipitation 
• Temperature 
• Temperature and Precipitation
• Humidity

Paleoclimatologists can use ocean and lake sediments to study the climate of the past. In these cores they look at the chemical composition of the soil and look at small fossils. From this they can determine the ___________ of the past.

• Precipitation 
• Temperature 
• Barometric Pressure
• Humidity
