EOC Standards - Students will be able to describe the relationship b/w the Earth and Sun and its effect of climate, weather and seasons. Essential Questions - Essential Questions -

How does the location of the suns rays impact our everyday life? Temperature Crop growth Location of cities Why does it affect these things?

Earth / Sun Relationships What is the difference between rotation and revolution? Rotation 1 spin around the axis = 24 hours/1 day Revolution 1 time around the sun = 1 time around the sun = days/1 year

Why do we have Seasons? Earth’s revolution and axial tilt change the amount of sunlight that parts of the Earth get from the sun. Axial tilt – 23.5* tilt

What are the important Latitude Lines? What are the important Latitude Lines? Arctic Circle- 66.5* North Tropic of Cancer- 23.5* North Why are the tropic lines at 23.5*? Equator – 0* Tropic of Capricorn-23* South Why are the tropic lines at 23.5*? Antarctic Circle- 66.5* South

When do the Seasons Begin? EQUINOX – Sun overhead at noon at Equator. Days and nights are same length. Spring Equinox - March 21, Fall Equinox - September 23 SOLSTICE – Sun overhead at noon at Tropics. Longest day in summer, shortest day in winter. Summer Solstice - June 20 or 21, Winter Solstice - December 22 or 23
