c. after 2pm, the water will be warm because it has taken all day to heat up.
which area would you choose to live if: you wanted a summer that was mild (75°) and a winter that was mild (60°)
a. an area that is close to a large body of water.
b. an area in the middle of land.
c an area in the mountains.
d. an area that close to the equator.

Explanation:

• First question:
• Water (a liquid) has a higher specific heat capacity than the surrounding air (a gas). It takes longer to heat up. So, it will be warmest after \(2\) pm as it has been absorbing heat all day.
• Second question:
• Large bodies of water have a moderating effect on temperature. They heat up and cool down more slowly than land. So, an area close to a large body of water will have milder summers and winters.

Answer:

• First question: c. after \(2\)pm, the water will be warm because it has taken all day to heat up.
• Second question: a. An area that is close to a large body of water.
