1. The cross section shows a sea breeze blowing from the ocean toward the land. The air pressure at the land surface is 1013 mb.
The air pressure at the ocean surface a few miles from the shore is most likely
994 mb (3) 1013 mb
(2) 1005 mb (4) 1017 mb

2. Unequal heating of the Earth’s surface by the sun causes a breeze at the beach.

3. Sea breeze is a big convection current (density change)
SUN heats water slowly
SUN heats sand quickly

6. After sunrise, a surface wind often develops between the water and land at the shore. Which map below best represents the direction of this wind?

10. Earth’s Rotation interferes though…

11. The planetary wind belts in the troposphere are primarily caused by the
(1) Earth’s rotation and unequal heating of
Earth’s surface
(2) Earth’s revolution and unequal heating of
(3) Earth’s rotation and Sun’s gravitational
attraction on Earth’s atmosphere
(4) Earth’s revolution and Sun’s gravitational
