Which of the following statements accurately describes the effects of large bodies of water on local variations in heat gain and loss?

A. Air pressure decreases near large bodies of water, so coastal areas are cooler.

B. Large bodies of water heat up and cool down slowly, causing coastal areas to heat up and cool down more gradually than does land far from the sea.

C. Coastal areas such as Pacific Northwest have hotter summers than inland areas such as the Midwest due to proximity to the ocean.

D. Large bodies of water heat up and cool down quickly, which makes coastal area hotter and more humid than areas farther inland.
