Why is it summer in New Orleans from
June 21- September 22 every year?
Keep the Do Now question in mind as we read
the lyrics with the song.

Planets moves through space in two major
ways: rotation and revolution
Rotation- the spinning its axis
• Axis – imaginary line through planet’s center and North
and South poles.
• Rotation causes day and night
• Takes 24 hours for one rotation
Revolution- movement of the planet around the
sun.

How many rotations of Earth take place
in one revolution around the sun?
The tilt of the Earth is the main factor: Because
the earth is tilted, it means that Earth gets
sunlight at different angles at different times.
Earth has seasons because its axis
is tilted as it revolves around the
sun. (23.5° from vertical)
The Earth is always tilted the same way, so
sometimes it is toward the sun and sometimes it
pointed away from the sun.
•
•
As Earth revolves around the sun, the north end is
tilted towards the sun for half of the year and
tilted away the other half.
•Summer and winter
are caused by the
Earth’s tilt not by
changes in Earth’s
distance from the
sun
(misconception).
•Earth is actually
farthest from the sun
during the northern
hemisphere’s summer

How sunlight hits the Earth affects
how warm an area is.

Sunlight hits more directly and over a smaller
area at the equator so it is warmer- these
areas are called the tropics

Sunlight hits at an angle and over a greater
area at the poles so it is colder
North end of Earth’s axis
is tilted toward the sun
 Sun is higher in the sky and there are more hours of
sunlight
 Sun’s rays are more direct
 It is summer in Northern Hemisphere
 South end of Earth’s axis is tilted away
 Sun is low in the sky, days are shorter than nights
 Sun’s rays are more slanted
 It is winter in southern hemisphere



Southern Hemisphere receives most direct
sunlight – their summer
Northern Hemisphere receives indirect
sunlight rays – our winter



Halfway between the solstices, neither
hemisphere is tilted toward or away from sun
Noon is directly overhead at the equator
Day and night are equal lengths - about 12
hours each
Occurs twice a year around March 21(Vernal
or spring equinox) and September 21
(autumnal equinox)


Day when the sun is farthest north of the
equator = about June 21 = Summer Solstice
(longest da) in the Northern Hemisphere and
Winter Solstice (shortest day) in Southern
Hemisphere
Day when the sun is farthest south of the
equator = about December 21= Winter
Solstice (shortest day) in Northern
Hemisphere and Summer Solstice (longest
day) in Southern Hemisphere

If Earth’s axis was not tilted, what would
happen to the length of days over the course
of a year? Would we have seasons?

You should be able to explain how the Earth’s
position affects temperatures, night and day
and the seasons. Give yourself a 0-5 rating in
the lower right corner of your exit ticket.
