In Boston, the bodies of water surrounding the city affect the temperature. The high specific heat of water causes it to cool and warm more slowly. Amherst not located in a coastal environment, but in an inland environment. This causes the temperature to be more moderate throughout the year. The tilt of the Earth throughout the seasons causes changes in solar radiation. Amherst is located in the North Hemisphere and is affected based on the sun’s location coupled with the Earth’s tilt. In the summer, the sun is located above the Northern Hemisphere while in the winter the sun is located farther away. The tropics receive more direct solar energy causing a greater amount of evaporation than in areas of higher latitude. The air is also warmer in the tropics which causes it to rise and condense. This leads to the air retaining more water.
