You set up an experiment to investigate the different rates at which soil and water heat and cool. You use the following equipment:Thermometers (measuring in °C)Container of soilContainer of waterRadiation LampTimerYou obtain the temperature of the soil and water over a period of time and collect the following data:The following graph was then made using the data.If you repeated this experiment but you let the water and the soil heat for 20 minutes and then cool for 20 minutes instead of the 10 minutes used in this experiment how you would expect the graph of temperature versus time to change?
Answer(s): B
Changing the length of time for the heating up period would allow both the soil and the water to reach higher maximum temperature values. The soil will still heat faster than the water so it will still have a higher curve on the temperature versus time graph than the water.

Since soil heats faster, the air above land should then be heated faster by the heat radiated by the land. This narrows the selection to choices B and D. Since the soil also cools faster, the air above the land will cool faster as it comes to equilibrium with the cooler ground temperature by losing heat to the ground. This narrows the final choice to B.

Answer(s): A
Since the air above the land heats and cools faster it will get warmer faster during the day. This means during the day the air over the land will be warmer than the air over the ocean. At night, however, the temperature of the land will cool faster than the temperature of the ocean. This means the air above the ocean will be warmer than the air above the land at night.

Air moves from cooler regions to warmer regions. When would a sea breeze occur?
During the day, the air above the land is warmer than over the ocean since the land heats faster than the oceans (as seen by the soil heating faster than the water in this experiment). Since air will move from cooler regions to warmer regions, the cool air over the ocean will move over to the land. This creates the sea breeze during the day.

Which of the following could be used to explain why your results are different?
Answer(s): C
It is not likely that unfiltered water or soil from your garden will heat differently than any other water or soil. Also, the size of the containers is not likely to affect the outcome of the experiment. However, if the heating lamp were faulty, it would cause your results to be inaccurate.
