Chapter 9: The Sun, the Moon and Earth

It takes 365 and 1/4 days for earth to do a _______ around the sun

• Rotation
• Revolution
• Circle
• Gyration
• Orbit

The imaginary line that goes in the north and south poles that earth rotates on is called the....

• Equinox
• Solstice
• Equator
• Axis

What causes day and night to occur on earth?

• Earth's Orbit
• Earth's Axis
• Earth's Revolution
• Earth's Rotation

Why does the temperature change the further you travel from the equator

• The further north or south you go the closer you get to ice making it colder
• The further north or south you go the less direct sunlight is received and when sunlight comes at angles it doesn't heat as much
• The further north or south you go the sun causes the wind to blow more due to changes in density
• The further north or south you go you run away from the sun, it can't get you if you hide well enough.

What is the MAIN cause of seasons on earth?

• The rotation of earth
• The tilt of the axis
• The revolution of the moon
• The orbit of earth

True or False, the tilt affects the amount of sunlight a location may get in a single day?

• False
• True

The day of the year when there is an equal amount of day and night

• Solstice
• Equinox
• Inertia
• Leap day

What is the force called that keeps the earth orbiting the sun and the moon orbiting the earth?

• Tension
• Friction
• Orbital
• Gravity

Which two factors determine how strong gravity is ?

• Rotation and Revolution
• Weight and Distance
• Weight and Mass
• Mass and Distance

The measure of the force of gravity on an object is its.....

• It's density
• Its Volume
• It's Mass
• It's Weight
