Earth-Sun Relationship
The earth is 93 million miles from the sun
3
Earth-Sun Relationship
The earth spins on its axis which is tilted at
23.5 degrees
But it also orbits the sun - it takes 365.25 days
to complete the orbit
4
Earth-Sun Relationship
Fall September 23
Winter December 21
Summer June 21
Spring March 21
The seasons change as a result of the earths
orbit and distance from the sun
5
Summer Solstice June 21st
-During the summer solstice the Northern
hemisphere receives more direct
sunlight. -During this time it is WINTER in the
southern hemisphere
6
Winter Solstice December 21
-During the winter solstice the southern
hemisphere receives more direct
sunlight. -During this time it is SUMMER in the
southern hemisphere
7
Fall Equinox September 23
-During the fall equinox neither hemisphere
receives direct sunlight
8
Spring Equinox March 21
-During the spring equinox neither hemisphere
receives direct sunlight

Latitude
  • Go to page 13
  • Start at the Arctic Circle
  • Locate 90 W
  • Record the climate you find at

10
_____,90 W
  • 75 N
  • 55 N
  • 46 N
  • 40 N
  • 30 N
  • 20 N
  • 17 N

11
Latitude
  • It affects temperature by influencing the
    intensity of the sun
  • It influences precipitation
  • Higher temps higher evaporation more
    precipitation

12
Land Versus Water
  • Stay on Page 13
  • Find southern Iceland (Reykjavik)
  • Trace with your finger east
  • What climate is found at Arkhangelsk, Russia?
  • Non-Coastal lands have no ocean currents to
    impact their precipitation or their temperature.

13
Go to page 36
  • Find Oregon
  • Trace from the Pacific coast at 42 N to eastern
    Oregon
  • How many climates did you pass through
  • Use the physical map on page 30 to explain the
    changes in climate

14
Mountains
  • Rain clouds moving over mountains lose tend to
    rain on one side leaving the other side dry
  • In addition, higher elevations have lower
    temperatures

Geographic Position/Winds
  • On page 36
  • Find and record the climate of Richmond,VA
  • Find and record the climate of St Louis, MO
  • Find and record the climate of San Francisco, CA

22
Geographic Position/Winds
  • Although Norfolk and San Francisco are both
    coastal cities, westerly winds change their
    climates
  • Even though some factors may be the same in two
    places, where a place is located can change a
    climate

23
Air Pressure
  • Pressure helps to create winds
  • Winds change temperature and precipitation
