At night, a land breeze forms because

• water release less solar energy during the day; warm ocean air moves onto land.

• Land cools more quickly than water; cool land air moves to replace rising water over the

• land absorbs less solar energy during the day; cool land air moves to replace rising warm air over the water.=.

• water absorbs more solar energy during the day; cool land air moves to replace rising warm air over the water.

In the northern hemisphere, convection creates __________ large convection cells that produce _____________ winds

• one;global

• six; global

• three; global

• four;westerly

As shown on the map, Norway and Southern Greenland on the same latitude (60° N). Why is Norway warmer than Southern Greenland in winter?

• Southern Greenland is closer to the North Pole than Norway.

• Norway has many active volcanoes which makes the weather warmer.

• Ocean currents carry heat toward Norway, but not toward Greenland.

• The North Pole is located in Greenland, making the place very cold.

The uneven heating of the atmosphere by the sun's energy creates pressure differences.

Which effect is a direct result of this?

• formation of clouds

• generation of winds

• occurrence of lighting

• an increase in humidity
