Elevation and proximity to coasts affects air temperatureB. Higher elevation can lead to colder temperatures and areas close to the coastwill have a smaller range of temperatures because water acts as a buffer of temperatureC. El Paso, Texas has a greater range of temperatures than North Head, Washington (on the Puget Sound)D. Water has a high heat capacity and moderates surface temperaturesE. Which side of Horsebarn Hill would have the most snow? The north side because the sun is in the south and shines less on the north side II. World Patterns of Air TemperatureA. Distribution of air temperatures shown on a map uses isotherms: lines of equal temperatureB. These maps reveal centers of low or high temperatures and temperature gradients, like contour maps for elevationC. Temperatures decrease from the equator to the polesD. Large landmasses located in the subarctic and arctic zones develop centers of extremely low temperatures in winterE. Yakutsk is the coldest place on earthF. Temperatures in equatorial regions change little from January to JulyThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.G. Isotherms make a large north-south shift from January to July over continentsin the mid-latitude and subarctic zonesH. The mountains cause changes in the temperature patternsI. Highlands are always colder than lowlands and areas of perpetual snow are always intensely coldJ. Antarctica is much colder than the Arctic because Antarctica is a large land mass and the Arctic is mostly the Arctic
