Begin in the west and move across the map to the east, briefly explaining why the actual 16°C (60°F) isotherm deviates from the hypothetical.
Using a straightedge, draw a line across the July temperature map (Map T-28b; shown in color at the back of the Lab Manual) from point “A” to point “B.” This reference line can be thought of as the “hypothetical” position of the 16°C (60°F) isotherm were there no land–water contrasts, ocean currents, and so on. Compare the actual 16°C isotherm, with the line you have just drawn. In places where the actual 16°C isotherm is south of the hypothetical line, temperatures are lower than expected; in places where the actual 16°C isotherm is north of the hypothetical line, temperatures are higher than expected.
