Do Now:
What is the difference
between revolution &
rotation? How do we
know the Earth is
doing both?

TWO Major Motions
1. ROTATION
- Spin on its internal axis
2. REVOLUTION
- Orbit AROUND something
WHAT DO YOU
KNOW ABOUT
THE EARTH’S
ROTATION???
Earth’s Rotation

360° turn about every 24 hours

15° per hour

1° per 4 minutes


Axis of rotation is tilted 23.5°
Counterclockwise
Who knows about Track???
Did you know…

A person standing at the equator
moves FASTER through space than a
person standing at 60 degrees N
Latitude.
0 degrees = 1674 km/hr
60 degrees N = 839 km/hr
for
Rotation
DAY AND NIGHT
SUNRISE AND SUNSET
Rises in the East,
Sets in
the
West!
SUNRISE
SUNSET
Coriolis Effect
“Bending of the Winds”
Earth’s West to East rotation causes winds
to travel across Earth to be bent clockwise
(N.H.) or counter-clockwise (S.H.)

Pendulum
• an object that is
attached to a pivot
which the pendulum
can swing freely
• Example:
Grandfather Clock
Léon Foucault
Jean Bernard Léon Foucault was a French
physicist best known for the invention of the
Foucault pendulum, a device demonstrating the
effect of the Earth's rotation.
FOUCAULT PENDULUM
Is…
A free swinging weight that changes
direction because of Earth’s
rotation.
Video Clip
Its behavior…
Shows how the Earth moves
COUNTER CLOCKWISE beneath it.
FOUCAULT PENDULUM
Who knows
anything
about
cameras???
Stellar Motion –
Star Trails
(counter clockwise):
The appearance of
Stars in the Northern
Hemisphere to Rotate
Counter Clockwise
around the North Star
(Polaris) under time
lapse photography.
Currently Polaris
aligns with Earth’s
Rotation Axis.
Earth’s Revolution

Counter Clockwise

Length – 365.25 days
•Why do we have a leap year???

Elliptical Orbit (oval shaped)
•Sun is at one FOCUS point
for
Revolution
Sun’s Apparent Change in Size
Sun appears to change size based on its
distance from Earth (closer = bigger)
The Seasons
Due to revolution and tilt of the Earth’s axis
Apparent Motions of Constellations
A group of stars that form a pattern
appear to change position yearly in our
night sky.
A Year of Constellations
SUMMER
WINTER
We see different constellations at different
times of the year.
The Winter Sky
Constellations
Which constellations are
both visible at
midnight to an
observer in NYS when
Earth is located at
position D?
1. Aries & Taurus
2. Pisces & Libra
3. Leo & Virgo
4. Aquarius &
Scorpio
Exam Review
1. Earth’s rate of rotation is approximately
(1) 1° per day
(2) 15° per day
(3) 180° per day
(4) 360° per day
2. The change in the tides as shown on the graph
is primarily the result of
(1) Earth’s rotation and the Moon’s revolution
(2) Earth’s rotation and revolution
(3) the Moon’s rotation and Earth’s revolution
(4) the Moon’s rotation and revolution
3. The best evidence that Earth rotates is provided by the
(1) locations of mid-ocean ridges and distribution of index
fossils
(2) movement of Foucault Pendulums and the Coriolis
Effect on the winds
(3) pattern of changing seasons and the depth of meteor
impacts
(4) rate of U-238 decay and changes in atmospheric
composition
4. Through what angle do the stars and planets seem to move in
2 hours?
(1) 2 degrees
(2) 15 degrees
(3) 20 degrees
Video Clip
(4) 30 degrees
