How long does it take for the Earth to make 1 rotation?
1 day, 24 hrs.

What is earth science?
Branch of science that deals with the physical composition of the Earth and its atmosphere.
200
In terms of space motion, what is the difference between revolving and rotating?
Revolving is going around an object. Rotation is spinning on object's own axis.
200
What causes an eclipse?
When 3 objects become perfectly aligned and one object casts a shadow on the other object.
200
How long does is take for the Earth to make 1 revolution around the sun?
1 year or 365 days
200
What 2 factors affect the law gravity between objects?
Mass and Distance
200
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.
300
What would happen if the moon didn't rotate?
We would see all sides of the moon's surface from earth.
300
Where is the moon located when the Earth experiences a solar eclipse?
The moon is in between the sun and the earth. The moon casts a shadow on Earth.
300
What causes seasons?
The tilt of the earth along with Earth's revolution around the sun.
300
What is mass?
The amount of matter that is contained in an object.
300
How does the sun affect the earth?
The affects the earth by:
1. Keeping the earth in orbit by its gravitational pull
2. Keeps us warm.
3. Light and energy allow plants to grow.
400
What causes moon phases?
The motion of the moon revolving around the earth.
400
What's the difference between the umbra and penumbra region?
The umbra is the area that experiences a total solar eclipse and the prenumbra experiences partial solar eclipse.
400
Which letter is labeled the summer solstice in Northern Hemisphere? (A, B, C, or D)
A. is labeled as the summer solstice for the Northern Hemisphere.
400
What causes moon tides?
The gravitational pull of the moon on the earth.
400
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.
500
Which phase is waxing gibbous?
Waxing gibbous is the picture above the full moon. Clock position is 10 o'clock.
500
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.
500
What motion of the earth causes day and night?
The rotation of the Earth on its axis causes night and day.
500
How does gravity affect the relationship between the Earth and Sun.
Gravity of the Sun keeps Earth in orbit and not flying out into space.
500
What is inertia?
An object in motion will stay in motion in a straight line forever, unless acted upon by another force.
