100
This is the name of the imaginary line that passes through the middle of the Earth from the North Pole to the South Pole.
What is the Earth's axis?
100
These are round pits on the moon.
What are a full craters?
100
This is the celestial body that is shadowed in a lunar eclipse.
What is the moon?
100
When the tides reaches its greatest height on the beach it is called this, and this is how many times a day we have them.
What is high tide and two?
100
This is Newton's First Law of Motion.
What is a body at rest will to stay at rest, and a body in motion will stay in motion at a constant speed and direction unless acted upon by an outside force?
200
This is the hemisphere I would be on if it was the first day of winter on June 21st.
What is the Southern Hemisphere?
200
This is the vocabulary word that describes the phase of the moon when the illuminated side is getting smaller.
What is a waning?
200
This is the celestial body blocked from view in a solar eclipse.
What is the Sun?
200
This is what it is called when the tide reaches its lowest point on the beach, and whether or not this measurement changes throughout a month.
What is the low tide, and yes it changes throughout the month?
200
How long does it take the moon to make one full rotation (it is the same number of days it takes the moon to make one full revolution around the Earth).
What is 29.5 days?
300
This is the day when the Sun's rays are directly over head at 23.5 degrees north latitude.
What is June 21st or the summer solstice?
300
These are caused by ancient lava flows on the moon.
What are marias?
300
This is how a solar eclipse occurs.
What is the moon must be direclty between the sun and the Earth blocking out the sun's rays in an umbra area on the Earth?
300
A neap tide is when there is the least amount of change between high and low tide. This is the relation the Sun, Moon, and Earth are in when the neap tide happens.
What is they are at right angles with the Moon on one end, the Sun on the other, and the Earth in the middle?
300
This is Newton's Universal Law of Gravitation.
What is every object in the Universe attracts every other object?
400
This is why we have seasons.
What is the 23.5 degree tilt of the Earth's axis?
400
Why do we see phases of the moon?
What is, although 1/2 of the moon is always lit by the sun, we only see the part of the sunlit moon that faces the Earth.
400
This is where the sun is directly overhead on December 21st.
What is over the parallel at 23.5 degrees south?
400
This is the description of a spring tide and what causes it.
What is when the Sun, Moon, and Earth are in a straight line causing the greatest gravitational pull, or the greatest difference between high and low tides?
400
This is what the strength of gravity depends on.
What is the masses of the objects and the distance between them?
500
This is the definition of an equinox. One is on September 21st (Autuminal Equinox) and the other is March 21st (Spring Equinox).
What is when the sun's rays are directly over the equator making equal day and night?
500
This is how the moon was formed.
What is, a large object, the size of a small planet, struck the Earth, and some material from the object combined with material from the Earth. This material was then trapped into orbit around the Earth?
500
The equinoxes and solstices on a planet that had a zero degree tilt would be this.
What is they would be nonexistant, the solstices and equinoxes are caused by of the tilt of the Earth?
500
This is what causes tides.
What is the gravitational pull from the Moon (greatest force) and the Sun (secondary force) on our oceans. As the Earth spins and the Moon revolves around the Earth, the gravitational force shifts causing high and low tides, and spring and neap tides?
500
This is what keeps the Moon in orbit around the Earth.
What are gravity and inertia?
