This PowerPoint explores how the sun's radiant energy affects the different layers of atmosphere. Specifically, it focuses on the effect solar energy has on Earths surface to create wind through the uneven heating of Earth's different surfaces (land vs. water)

1. Solar Energy
Uneven Heating of Earth CAUSES…
Movement of Air Masses

2. Sea Breeze
Radiation = the transfer of
energy though space by
electromagnetic waves.

3. Sea Breeze
What do you notice about
the temperatures?
Warm Land
Cool Water

4. Sea Breeze
Hot air rises
Cool Water
Warm Land

5. Sea Breeze
Warm air
begins to cool
as it rises
Cool Water
Warm Land

6. Sea Breeze
Warm Air flows to cooler air
Cool Water
Warm Land

7. Sea Breeze
Cooled air
Sinks b/c it is
more
dense
Cool Water
Warm Land

8. Sea Breeze
Warm Air flows to cooler air
Cooled air
sinks
Hot air
rises
Wind blows from Cool water to warm land
Cool Water
Warm Land

9. Sea Breeze
Cool Water
Warm Land

10. Land Breeze – At Night

11. Land Breeze
Now… what's
different about the
temperatures?
Warm Water
Cool Land

12. Land Breeze
Now… what's different
about the temperatures?
When the sun is down,
we have cooler LAND
and warmer WATER.
Warm Water
Cool Land

13. Land Breeze
Warm Water
Cool Land

14. Land Breeze
Heat can be transferred
in 3 ways…
Conduction, Radiation,
Convection
The sun provides heat energy
called RADIATION and it creates
CONVECTION Currents in our
atmosphere.

15. Sun’s Rays
“Uneven Heating of the Earth due to
the curvature of Earth”

16. 90°
• Larger Angle =
More intense
heat (hotter)
• Acute Angle =
less intense heat
(cooler)
EARTH
45°

17. Curved Earth = Sun rays hit Earth at angles
90°
Right Angle = Very intense heat (HOT)

18. Curved Earth = Sun rays hit Earth at angles
45°
Acute Angle = less intense heat (cooler)
90°
45° Acute Angle = less intense heat (cooler)

19. Curved Earth = Sun rays hit Earth at angles
Coldest
at the
Poles
30°
VERY acute Angle = less intense heat (coldest)
45°
