Earth in Space
Gravity and Motion
Phases Eclipses and Tides
100
Astronomy
What is The study of the moon stars and other objects in space
100
Equinox
What is The two days of the year on which neither hemisphere is tilted toward or away from the sun
100
What is the difference between Rotation and Revolution
What is The spinning of a planet around something is a revolution and the spinning of a planet on its axis is a rotation
100
the two factors that contribute to the strength of gravity and what happens when you change them
What is greater mass greater gravity and less distance less gravity
100
What causes the moon's phases
What is the amount of the sunlit side of the moon faces earth
200
when do low/high tides occur
What is high tides occur directly under where the moon is over earth and on the opposite point of the earth low tides occur between the two high tides
200
Universal Law of Gravitation
What is A law stating all objects in the universe are drawn toward each other
200
Earth orbits around the sun every 365 1/4 days
Why do we have a leap year every four years
200
The force of gravity on an object
What is weight
200
why does the moon shine
What is the reflection of sunlight off the moons surface
300
Inertia
What is The tendency of an object to resist a change in motion
300
Axis
What is An imaginary line that passes through earth's center and the North and South poles where Earth rotates
300
What causes day and night
What is Earths rotation around its axis
300
the difference between mass and weight
What is weight can change on other planets with less or more gravity
300
what is the difference between soar and lunar eclipses
What is solar eclipses block sunlight from earth and lunar eclipses block sunlight from the moon
400
Orbit
What is The path of an object as it revolves around another object in space
400
Lunar Eclipse
What is The blocking of sunlight to the moon when earth is between the two
400
Solstice
What is The two days of the year on which the sun reaches its greatest distance north or south of the equator
400
Newton's first law of motion
What is an object at rest will stay at rest and an object in motion will stay in motion unless acted on by an unbalanced force
400
The differences in how much the moons gravity pulls on different parts of earth
What is the cause of tides
500
Solar Eclipse
What is The blocking of sun light to earth when the moon is inbetween
500
Rotation
What is The spinning of a planet on its axis
500
Why does earth have seasons
What is earths axis is tilted as it revolves around the sun
500
the two factors that keep planets in orbit
What is gravity and inertia
500
why is a day and a year the same on the moon as on earth
why does the moon rotate at the same speed
