Universe Summative Assessment

What is gravity?

• The force of attraction that moves objects toward its center.
• The orbital path of an object around another object.
• The imaginary line that an object spins on.
• When a celestial body (object in space) is blocked (or partially covered) by another object in space.

What is revolution?

• The force of attraction that moves objects toward its center.
• The orbital path of an object around another object.
• The imaginary line that an object spins on.
• When a celestial body (object in space) is blocked (or partially covered) by another object in space.

What is an axis?

• The force of attraction that moves objects toward its center.
• The orbital path of an object around another object.
• The imaginary line that an object spins on.
• When a celestial body (object in space) is blocked (or partially covered) by another object in space.

What is an eclipse?

• The force of attraction that moves objects toward its center.
• The orbital path of an object around another object.
• The imaginary line that an object spins on.
• When a celestial body (object in space) is blocked (or partially covered) by another object in space.

What is rotation?

• The spinning of an object on its axis.
• The orbital path of an object around another object.
• Rays of sunlight that strike Earth straight on.
• Rays of sunlight that strike Earth strike Earth at an angle and not straight on.

What are direct light rays?

• The spinning of an object on its axis.
• The orbital path of an object around another object.
• Rays of sunlight that strike Earth straight on.
• Rays of sunlight that strike Earth strike Earth at an angle and not straight on.

What are indirect light rays?

• The spinning of an object on its axis.
• The orbital path of an object around another object.
• Rays of sunlight that strike Earth straight on.
• Rays of sunlight that strike Earth strike Earth at an angle and not straight on.

What causes seasons?

• The moon

• The earth spinning on its axis
• How close the earth is to the sun

How do you know if it is winter?

• The tilt of the earth in the Northern Hemisphere is pointed toward the sun.
• The tilt of the earth in the Northern Hemisphere is pointed away from the sun.
• When the weather is cold.
• None of these.
