Answers to Heating Land and Water Lab

1. The sand heated up the fastest. The slope of its line is steeper than that of the water.

2. The sand cooled at a faster rate. . . again, its line is steeper

3. According to the text that we use here at Helena High (Heath Earth Science by Spaulding and Namowitz) . . . One reason is that the sun's rays penetrate deeper into the water. A second is that, since water is a fluid, it can spread the heat more evenly within itself. A third is that water simply needs more energy to raise its temperature (higher specific heat). Finally, some the energy from the water is used to evaporate water from the surface. Thus, less of the energy is used to heat the water.

4. Bismarck would get hotter. Seattle would be affected the large body of water which heats more slowly than the continent.

5. Bismarck.

6. Anchorage is near the Gulf of Alaska where a tremendous amount of heat are stored. This heat tends to make the winter temperatures not as cold as they might be if Anchorage were far from the gulf.

7. The coldest area is not at the North Pole (over water) as some might expect, but rather in Siberia (northern Russia).

7. Southward . . . colder over land
