What is earth science?
Branch of science that deals with the physical composition of the Earth and its atmosphere.
In terms of space motion, what is the difference between revolving and rotating?
What causes an eclipse?
When 3 objects become perfectly aligned and one object casts a shadow on the other object.
How long does is take for the Earth to make 1 revolution around the sun?
1 year or 365 days
What 2 factors affect the law gravity between objects?
Mass and Distance
How does the moon affect the earth?
The moon affects the earth by:
1. Casting shadows that create solar eclipses.
2. Reflects different shapes of light as the moon revolves around the earth.
3. The moon gravitational pull causes ocean tides.
What would happen if the moon didn't rotate?
We would see all sides of the moon's surface from earth.
The moon is in between the sun and the earth. The moon casts a shadow on Earth.
What causes seasons?
The tilt of the earth along with Earth's revolution around the sun.
What is mass?

What causes moon tides?
The gravitational pull of the moon on the earth.
How does the law of gravity affect us?
We are able to stay on Earth and float away. Our weight may change based on the amount of gravitational pull is exerted on us, yet our mass stays constant.
Which phase is waxing gibbous?
Waxing gibbous is the picture above the full moon. Clock position is 10 o'clock.
Why isn't there a total solar eclipse every month?
The alignment of all 3 objects isn't always perfectly aligned because the orbit plane of the moon wobbles.
What motion of the earth causes day and night?
The rotation of the Earth on its axis causes night and day.
Gravity of the Sun keeps Earth in orbit and not flying out into space.
What is inertia?
An object in motion will stay in motion in a straight line forever, unless acted upon by another force.
