At night, the air above the ocean is warmer than the air above the land (land heats/cools quicker), so there is high pressure on shore and low pressure over the water. Wind blows from high to low pressure.
BONUS - worth 100 pts.

What weather variable is the amount of water vapor in the air (%)
Humidity
BONUS - worth 50 pts.
Which temperature holds more water vapor, cold or hot?
What front is formed when two cooler air masses push up a warm air mass?
occluded front

Describe the symbol for this front
What global wind is responsible for most of the weather in the United States?
westerlies
BONUS- worth 100 pts.
Which global wind brings hurricanes to the United States?
What is the Coriolis Effect?
the way Earth's rotation makes winds curve
BONUS - worth 100 pts.
If you are at the equator and throw a paper airplane to someone at the North Pole, how would you need to throw it -- straight, to the left, or to the right?
What air mass would be found over the oceans near Antarctica?

What is the difference between "weather" and "climate?"
weather: conditions in a specific place at a specific time
