Title: Sun, Earth, and Moon


1
Sun, Earth, and Moon
2
  • What causes day night?
  • Which one is bigger the earth or the moon?
  • Where does the moon get its light from?
  • What percent of the earth is always lit by the
    sun?
  • How many stars are in our solar system?
  • How many days does it take for the Earth to
    revolve around the sun?
  • How many low and high tides on Earth every 24
    hours?

3
The Earth
  • -is the third planet from the Sun,
  • -is an oblated sphere,
  • -rotates on its imaginary
  • axis counterclockwise every
  • 24 hours or 1 day,
  • -appears blue in space
  • because it is 70 water,
  • -revolves around the sun every
  • 365 days or 1 year.

4
We breathe
  • 78 nitrogen
  • 21 oxygen
  • 1 argon, neon, carbon dioxide, neon, krypton

5
Which one is the smallest? Which one is the
largest?
  • Can you put these in size order?
  • Place the following in order from largest to
    smallest.
  • Moon
  • Sun
  • Earth

6
Answer Sun, Earth, then moon
  • The sun is the largest
  • Next in size is the Earth.
  • The moon is smaller than the Earth.

7
2000 SOL 4.7
  • Which of these is the biggest?
  • F The moon
  • G The Earth
  • H The sun
  • J Jupiter

8
Answer H The sun is the largest!
  • Our sun is the only star in our solar system. The
    sun is also the largest heavenly body in our
    solar system.

9
Earth Patterns,Cycles, and Change - SOL 3.7, 4.7
  • The sun heats the Earth unevenly, making the
    poles cold and the tropics hot, because-
  • A the tropics face more directly
  • toward the sun
  • B the poles are covered with ice
  • which causes cold air
  • C seasons change
  • D weather changes

10
2001 SOL 3.7 4.7
  • The moon revolves around -
  • F itself
  • G the Earth
  • H the sun
  • J the solar system

11
  • The moon revolves or orbits the Earth once every
    29 days.
  • We all ways see the same side of the moon because
    the moon rotates and revolves at about the same
    speed.

12
Earth Science Question rotation
  • What is rotation? (define)
  • The rotation of the Earth on its axis causes-
  • A days
  • B months
  • C seasons
  • D years

13
Rotation causes day night.
  • Rotation is the turning or spinning of the Earth
    in one place on its imaginary axis.
  • Rotation of the earth on its axis causes day
    night. (answer A).

14
Earth Science Question
A
  • Which of these shows the location of a polar ice
    cap?
  • Which of these shows the location of the equator?

B
C
C
D
15
Polar ice caps A Equator C
90º latitude
0º latitude
16
Which of these is caused by the turning of the
Earth?
  • F Summer and winter
  • G Stars
  • H Day and night
  • J Moon phases

17
The turning of the Earth causes
  • Day Night

18
When the moon is seen from the Earth as a whole
circle, it is called a-
  • A Crescent moon
  • B Full moon
  • C Half moon
  • D New moon

19
When the moon is seen from the Earth as a whole
circle, it is called a FULL MOON.
20
Which of these is the next phase of the moon?
  • New Moon --- Waxing Crescent --- ?
  • F Full Moon
  • G Waning Crescent
  • H First Quarter
  • J Waxing Gibbous

21
The next major phase of the moon would be
  • First quarter.
  • Just think about itthe
  • New moon (can only get bigger. Or Waxing)..
  • Then comes Waxing crescent next is
  • First quarterthen
  • Waxing Gibbous and then a
  • Full Moon.

22
The revolution of the Earth around the Sun takes-
  • A a day night or 12 hours
  • B a week or 7 days
  • C a month or 29-31 days
  • D a year or 365 days

23
The revolution of the Earth around the sun
  • Takes 365 days
  • or one year.
  • NOTE
  • Due to the tilt of the Earths axis during
    revolution, the Earth experiences seasons.
