QuestionAnswer
A pattern of stars in the sky. Constellation
The Big Bang theory The theory that an explosion caused the expansion of the universe to create time and space.
How the Big Bang "happened" All contents of the universe were compressed under extreme pressure and exploded
Galaxy A large group of stars, dust and gas that are held together by gravity.
Imaginary line around which Earth spins Axis
The spinning of Earth on its axis rotation
How long it takes for the Earth to make 1 rotation 24 hours
The motion of Earth around the Sun revolution
The cause of day and night rotation
How long it takes for the earth to do one revolution 365 1/4 days
The curved path followed by Earth as it moves around the Sun orbit
What makes gravity higher bigger mass, closer distance
What makes gravity smaller smaller mass, bigger distance.
The reason we have the seasons (spring, summer, winter and fall) The Earth is tilted on its axis as it revolves around the Sun.
When the Moon casts its shadow on Earth Solar eclipse
When the Earth casts its shadow on the Moon Lunar eclipse
The cause of the tides The Moons gravity pulls the ocean into a tidal bulge

The moon phase that happens during a lunar eclipse full moon
The moon phase that happens during a solar eclipse new moon

The alignment for a lunar eclipse Sun- Earth- Moon or Moon- Earth- Sun
The type of tide with higher high tides and lower low tides Spring tide
The type of tide with a small difference between tide heights Neap tide
The reason the height of the tides varies The moon is always revolving around the Earth changing the gravitational effect on the water along with the Sun.
Who can see the solar eclipse Anyone in the moon's shadow.
Who can see the lunar eclipse Anyone on the night side of Earth.
What makes the Spring tides bigger the Sun's gravity pulling in line with the Moon's gravitational pull
What makes the Neap tides smaller The Sun's gravity pulling at a 90 degree angle to the Moon's gravitational pull.
