Surface Water and Global Temperature

1. Thermal Inertia: San Francisco and Norfolk, Virginia are on the same latitude. Why would Norfolk, compared to San Francisco, have warmer summers and cooler winters?
 - Its because air in San Francisco has moved over the ocean, while air in Norfolk has approached over land, water doesn't warm as much as land in the summer nor cool as much as in water.

2. Describe the different ways temperature are "moderated" on earth. Without moderate temperatures, Earth could not support life as we know it. - Water takes much longer than air to heat up and also longer to cool, because it has a much higher specific heat.
