The time required for a
planet to rotate on its axis
one complete time is
known as what?
day
Periodic rise and fall of the
water level in the oceans and
other large bodies of water
are known as what?
Tides
When the shadow of one
celestial (in space) body falls
upon another celestial body
it is called an:
Eclipse
The path that a body follows
as it travels around another
body in space is known as
what?
Orbit
The two days per year
where neither pole is tilted
more toward the sun are
known as what?
Equinoxes
The movement of a body
traveling around another
body in space is called:
revolution
Who was the German
astronomer that developed
the laws of planetary
motion?
Johannes Kepler
The scientific law that states
that planets move around
the sun in elliptical paths
is called:
Kepler’s First Law of
Planetary Motion
“The force of gravity depends on
the product of the masses (m x m),
divided by the square of the
2
distance between them (d ),”
is known as what scientific law?
Newton’s Law of
Universal Gravitation
What is Kepler’s
Second Law of
Planetary Motion
planets move faster the closer
they are to the sun
What force causes the
tides to rise and fall
each day?
Gravitational pull of
the Moon
The two days every year
where there are exactly the
same number of
daylight hours as dark
are known as what?
Equinoxes
“The time it takes a planet to
orbit the sun is directly
proportional to the distance the
planet is from the sun”
is known as what scientific law?
Kepler’s Third Law
of Planetary Motion
The change in sunlit area of
one celestial body
(in our case, the moon)
as seen from another celestial
body is called what?
phases
The two days per year
where the axis of the Earth
leans towards (or away
from) the sun the most.
Solstices
If the mass of the earth
were doubled, how would
that affect your weight?
Your weight would double
The difference in levels of
ocean water between high and
low tides is known as what?
Tidal Range
What kind of eclipse
happens when the shadow of
the moon falls on the Earth?
Solar Eclipse
When moon phases are
waning, the sunlit part of the
moon is in the process of
getting ______________.
smaller
The two days per year where
we have either the most
amount of sunlight or the
least amount of sunlight are
called what?
Solstices
What kind of eclipse happens
when sections of the sunlit moon
are blocked out by the shadow
of the earth
Lunar Eclipse
Name a season of the
year when an equinox
might occur.
Spring or Fall
Tides of increased tidal
range which occur when
the SUN-EARTH-MOON
are in a straight line are
known as what?
Spring Tides
When moon phases are
__________, the sunlit part of
the moon is in the process of
getting larger
Waxing
Tides of decreased tidal
range which occur when
the SUN-EARTH-MOON
0
form a 90 angle are
known as what?
Neap Tides
Because the time required
for one rotation of the
Earth and one revolution of
the moon are ___________,
we always see the same side
of the moon.
equal
Name a season of the
year when a solstice
might occur.

What fact about the Earth’s
axis causes there to be
changing seasons in many
places on the earth?
0
23.5 tilt
If the distance between two
bodies in space increases,
what happens to the force of
gravity between them?
decreases
When the north pole is pointing
towards the sun, what season is
it in California?
Summer

curve are always equal is known as
what?
Ellipse
What kind of tide has the
lowest high tide?
Neap tides
What kind of tide has the
lowest low tide?
