10. WHAT DETERMINES THE STRENGTH OF THE
FORCE OF GRAVITY BETWEEN 2 OBJECTS?
• Distance between objects…the closer they are
the stronger the pull of gravity
• Size of the objects…the bigger they are they
more the pull of gravity
11. WHAT TWO FACTORS COMBINE TO KEEP
THE MOON AND THE EARTH IN ORBIT?
• Gravity—pulling it towards the Sun
• Inertia-objects in motion stay in motion

19. WHAT CAUSES THE PHASES OF THE MOON?
• Phases depend on
how much of the lit
side of the moon we
see on Earth
• Takes 28-29 days to
complete the
cycle…about a
month
20. LABEL THE PHASES OF THE MOON

• Solar Eclipse
21. WHAT ARE SOLAR AND LUNAR ECLIPSES?
• Lunar Eclipse
22. WHAT CAUSES THE TIDES?
• The Alignment of the Sun, moon, and the Earth.

30. WHAT OBJECTS MAKE UP THE SOLAR
SYSTEM?
• Sun
• Moon
• 8 Planets
• Asteroids, comets, meteroids
31. WHAT ARE THE LAYERS OF THE SUN’S
INTERIOR?
32. WHAT CHARACTERISTICS DO THE INNER
PLANETS HAVE IN COMMON?
• Small
• Solid or rocky
• No rings
• Few or no moons
33. WHAT CHARACTERISTICS DO THE OUTER
PLANETS HAVE IN COMMON?
• HUGE
• Made out of gas
• Many rings
• Many, many moons
34. WHAT ARE THE CHARACTERISTICS OF
COMETS?
• Ice, dust and rocky particles caught in
an orbit around the Sun
35. WHERE ARE THE MOST ASTEROIDS FOUND?
• In the asteroid belt between the inner and
outer planets
36. WHAT ARE METEOROIDS AND HOW DO THEY
FORM?
• Chunks of rock or dust in space
• They typically come from asteroids or comets
• They do not have a set orbit
• Meteoroid  Meteor  Meteorite
37. WHAT IS A STAR SYSTEM?
• Stars that are members of groups of 2 or
more stars
38. WHAT ARE THE MAJOR TYPES OF
GALAXIES?
• Spiral, Elliptical, Irregular
• They are groups of stars bound together by
Gravity
• We live in a spiral Galaxy called the Milky Way
MILKY WAY-TOP VIEW
Sun s location
MILKY WAY-SIDE VIEW
Sun’s location
39. WHAT IS THE BIG BANG THEORY?
• Enormous explosion that created our
universe
• Continues to expand today
40. HOW DID THE SOLAR SYSTEM FORM?
• About 5 billion years ago a cloud of dust
collapsed to form the Sun and the planets
• The planets formation is called the Dust
Cloud Theory
41. WHAT DO ASTRONOMERS PREDICT ABOUT
THE FUTURE OF THE UNIVERSE?
• Continue to expand further and further apart
• Expand to a point, then snap back like a
rubber band
