100

Where are ice cores found?

Antarctica 

100
One example of a natural sink and one example of a natural source?

A plant is a natural sink and the ocean. A natural source is a decomposing organism, an animal, or the ocean. 

100

How are greenhouse gases released into the atmosphere?

by burning fossil fuels 

100

How are CO2 levels and temperature related?

As CO2 levels increase temperature increases. 

200

What do scientists use to find out information about the earth's climate 500,000 years ago? 

Ice Cores

200

What are the carbon sources humans utlize every day (something humans do that burns fossil fuels)  

Drives a car, uses gas to heat their car or home, factories burning coal 

200

What has happened to the amount of greenhouse gases in the atmosphere in the past 150 years?

Increased immensely 

200

True or False? The earth has experienced "climate change before"?

Yes, but not as these temperatures and rate 

300

What is the name of the molecule scientists analyze when looking at ice cores? 

CO2

300

What can be a natural source and sink?

the ocean 

300

How have humans made the Earth get hotter?

More CO2 produced by humans is trapping too much heat

300
How are dinosaurs and climate change related?

The astroids that killed the dinosaurs generated an ice age killing off the majority of life on planet earth. 

400
Where do the bubbles in the ice cores come from? Where are the molecules the scientists are investigating coming from? 

The snow that falls each year, that traps small air bubbles in the atmosphere. Each layer of snow contains small amounts of the atmosphere.

400

How do human sources of carbon dioxide compare to natural ones?

There are a lot more humans on this planet, than there are natural sources. 
400
Other than Carbon Dioxide (CO2) name two other greenhouse gases?

Nitrous oxide (N2O)

Methane (CH4)

400

How are fossil how are fossil fuels made?

Fossil fuels are formed when organic matter that has been buried deep within the earth are subject to heat and pressure over millions of years.

500

How do scientists learn information about temperature from 500,000 years ago...scientist measure the____________________present? 

the relative amount of oxygen 

500

Would a magic CO2-human-made-sink machine help global temperatures and CO2 levels decrease? (Be ready to explain your answer 

No...

500

What human activity can have the greatest positive change on global climate change by helping to reduce the amount of carbon dioxide in the atmosphere?

Limiting engines that use fossil fuels for energy

500

If the earth warms up +4C what will happen to the world?

Large portions of the continents would be underwater.
