Revolution is the movement of the Earth around this.
What is the Sun?
100
Revolution is the spinning motion on this. Hint: You cannot see it.
What is the Axis?
100
The Earth is warmer near this place then at the North and South Poles because of how the sunlight hits the Earth.
What is The Equator?
100
The force of gravity between two objects depends on this.
What is the size, mass, and weight of the object?
200
When daytime equal nighttime, March 21st or 22nd.
What is the Vernal Equinox?
200
The orbit of the Earth around he sun is not quite circular so it is called this.
What is an Elongated Circle?
200
Rotation causes these two things to happen.
What is Day and Night?
200
When the Northern Hemisphere is experiencing this season the north end of the axis is tilted towards the sun
What is Summer?
200
If a mass of an object does this and the distance stays the same, then the force of gravity on an object decreases.
What is decreases?
300
This hemisphere is tilted towards the sun when there is the longest amount of daytime.
What is the Northern Hemisphere?
300
The revolution of the Earth around the Sun takes this many years.
What is one year?
300
It takes 24 hours for the Earth to do this around the Sun
What is Rotation?
300
This hemisphere has winter when the north end of the axis is tilted away from the sun.
What is the Northern Hemisphere?
300
The strength of the force depends on these two factors.
What is the mass of the two objects and the distance between them?
400
This day in the Northern Hemisphere is when there is the shortest amount of daytime.
What is the Winter Solstice or December 21st or 22nd?
400
This is what Earth follows around the Sun.
What is an Orbit?
400
Earth's axis is always tipped at this many degrees.
What is 23.5 degrees?
400
Near the North and South Poles the sunlight arrives at an angle so it is more this than direct.
What is spread out?
400
This is the force of gravity on an object.
What is weight?
500
The Autumnal Equinox, or when the amount of daytime equals nighttime, is on this date.
What is September 21st or 22nd?
500
The a total revolution of the Earth around the Sun takes this many days total.
What is 365.25 days?
500
The combined effect of the Earth's tilt and its orbital motion causes these to happen throughout the year.
What are the Seasons?
500
At the Equator the weather is more of this temperature because the sunlight hits it directly.
What is warmer?
500
This law explains that an object at rest remains at rest and an object in motion will remain in motion with a constant speed and direction unless stopped by a force.
