 The spinning motion of an object on its axis
Tops, Ballerinas, Figure skaters, cyclones, Tornadoes, a
merry-go-round, Earth
 The movement of the earth on its axis over a
24 hour period.
 The speed of rotation 24,855 miles/24 hr or
1,038 miles/hr
 Day and Night.
◦ As the earth rotates on the axis one half faces the
sun, this half experiences day while the other half
experiences night.
 High and Low tides.
 This occurs when the earth spins and the sun and the
moon pull it. One force is usually stronger than the
other.
 Wind speed and Direction
 Wind on earth comes from different direction
(North, South, East and West).
Different places would get stronger surge of wind as
a result of the earths speed of rotation.
 The movement of an object around another object
 This is the movement of the earth around the sun.
 It takes 365 ¼ days (one year)
 The speed of earth’s revolution is about 18 miles per
second.
 Earth revolves around the sun in a slightly eccentric
elliptical orbit or path once a year
 Every second, that you sit in this classroom, the Earth's
orbital motion carries you about 18 miles through
space.
 Seasonal variations (varying lengths of day
and night).
Summer, Winter, Autumn and Spring.
 Solstices and Equinoxes
 The “solstice” is the day of the year when sunlight is
furthest north or south of the equator
 Our summer solstice occurs on June 21st, the first day
of summer.
 Our winter solstice occurs on December 21st, the first
day of winter
 The “equinox” occurs twice a year when the sun is
directly overhead at the equator
 On the equinox, the hours of daylight equals the hours
of darkness.
 Seasons in the northern & southern hemispheres are
opposite
 Our vernal equinox occurs around March 21st, the first
day of spring
 Our autumnal equinox occurs around September 21st,
the first day of fall
 What is the difference between rotation and
revolution?
 Give me an example of something that revolves,
and something that rotates.
 What type of movement causes night and day?
 What type of movement causes the change of
seasons?
Rotation occurs when an object spins around an axis.
Revolution occurs when an object spins around another object
Revolving
Rotating
 The Earth’s rotation
 The Earth’s revolution- the angle of the sun, and the
length of the day
