100
A force that attracts all objects toward each other is called..
Gravity
100
What causes the phases of the moon, eclipses, and tides?
The changing relative positions of the moon, Earth, and sun cause this.
100
What happens during an eclipse?
The moon's shadow hit the Earth or the Earth's shadow hits the moon.
200
The tendency of an object to resist change in motion is called...
inertia
200
Why is it warmer near the equator than near the poles?
The equator gets the most direct sunlight and the poles get less direct sunlight
200
What two factors determine the force of gravity?
mass of objects and distance between them
200
Describe a solar eclipse.
occurs when a new moon blocks your view of the sun
300
A tide with the greatest difference between consecutive low and high tides.
spring tide
300
Explain why there are different seasons on Earth.
The Earth's axis is tilted as it revolves around the sun.
300
What is the difference between mass and gravity?
mass is the amount of matter in an object and gravity is a force.
300
The different shapes of the moon you see from Earth are called...
phases
300
Describe a lunar eclipse.
Earth blocks sunlight from reaching the moon.
400
A tide with the least difference between consecutive low and high tides.
Neap tide
400
What is an equinox and when do they occur?
During an equinox, day and night are each about 12 hours long. They occur around March 21st and September 22nd.
400
Contrast your gravity to the gravity of Mr. Oesch.
Mr. Oesch would have more force of gravity because he has more mass.
400
What determines the phase of the moon we see on Earth?
It depends on how much of the sunlit side of the moon faces Earth.
400
What causes high tide?
the force of the moon's gravity pulls Earth toward the moon and the moon's gravity causes high tide on the side closest to the moon.
500
The rise and fall of the ocean water.
tides
500
What phase or phases of the moon is it possible for a spring tide to occur?
New moon and full moon
500
How does Newton's first law of motion keep the Earth from flying off into space?
Inertia and gravity combine to keep Earth n orbit around the sun and the moon in orbit around the Earth.
500
How often does the moon go through an entire phase?
About 29.5 days
500
What causes tides?
They are caused by differences in how much the moon's gravity pulls on different parts of the Earth.
