Chapter 9 Review
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 distance between them (d2),”
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 form a 900 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.
Winter or summer
What fact about the Earth’s axis causes there to be
changing seasons in many places on the earth?
23.5 0 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
Toss Up Questions
What kind of tide has the highest low tide?
Neap tides
Why don’t we see lunar and solar eclipses every
month?
The orbit of the moon is tilted 50 off that of the Earth
What kind of tide has the highest high tide?
Spring tides
A closed curve in which the sum of the distances from the edge of the
curve to two points inside the 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?
Spring tides
What kind of eclipse occurs when most of the sun is blocked out by
the moon but the moon appears to not be large enough to block out
the entire sun?
Annular Solar Eclipse
