Sea level rise is caused largely due to which kind of ice melting?
Land ice (glaciers, snow/ice caps, etc.)
100
Thermal energy describes what?
Movement of particles
100
Provide the name of 1 common greenhouse gas
Carbon dioxide, Nitrous oxide, methane, water vapor, ozone
100
What is a control?
A baseline condition where no influence from independent variables is involved. This allows a researcher to determine whether the effects of manipulating independent variables actually causes a real change.
100
Is the following image an example of a positive or negative feedback loop?
Positive
200
Areas near the equator are more likely to experience sea level rise than areas further away from the equator due to...
Being warmer (water will undergo thermal expansion)
200
What is the difference between chemical and nuclear energy?
Chemical = energy stored in bonds between atoms
Nuclear = energy stored due to interactions of particles in an atom's nucleus
200
What does the greenhouse effect describe?
The heating of the planet's surface due to gas accumulation in the atmosphere
200
What is the difference between a dependent and independent variable?
Dependent = change that occurs due to effects of independent variables (the result being observed)
Independent = the variables that a scientist has direct control over (the environmental conditions that impact results)
200
Is the following diagram an example of a positive or negative feedback loop?
Negative
300
Provide a couple of reasons why Antarctica is melting slower than Greenland.
Larger volumes of ice melt slower
Anarctica is in a polar region, so it is less likely to experience seasonal changes
300
Where is heat being illustrated in the provided image?
The flame (heat)
300
According to the provided graph, what is most responsible for increases in global temperatures?
human factors
300
According to the diagram provided, what would the dependent variable of the experiment be?
Observed growth
300
What is the difference between a positive and negative feedback loop?
Negative feedback = conditions return to normal after a change occurs
Positive feedback =conditions continue to move further away from normal after a change occurs
400
Why doesn't water that has recently come from melted ice have any notably changes on the sea level in areas near melting ice?
Colder water sinks and often travels along the sea floor until it warms up enough to rise. This normally occurs somewhere closer to the equator and therefore does not cause noticeable sea level changes where the ice originally melted.
400
Which specific form of potential energy is being described by the provided image?
Gravitational potential energy
400
According to the graph provided, if too much carbon dioxide is in the atmosphere, where does excess carbon dioxide go?
The ocean
400
Why might it be an issue for a scientist to run a clinical trial of a newly developed drug and specifically get to choose who receives the drug and who does not?
This may result in biased results because the subjects taking the drug may not actually be random enough to represent realistic effects that would occur in the general population

What is an example of a positive AND negative feedback loop that exists on Earth that has to due temperature regulation?
Greenhouse effect = positive feedback loop
Water cycle = negative feedback loop
