Seasons and Orbital Motion

What is the definition of inertia?

• The spinning motion of a planet on its axis.
• The scientific law that states that every object in the universe attracts every other object.
• The tendency of an object to resist a change in motion.
• The attractive force between objects; the force that moves objects downhill.

What is the definition of orbit?

• An imaginary line that passes through a planet's center and its north and south poles, about which the planet rotates.
• The spinning motion of a planet on its axis.
• The path of an object as it revolves around another object in space.
• The movement of an object around another object.

What is the definition of equinox?

• Either of the two days of the year on which neither hemisphere is tilted toward or away from the sun.
• Either of the two days of the year on which the sun reaches its greatest distance from the equator.
• The tendency of an object to resist a change in motion.
• The attractive force between objects; the force that moves objects downhill.

What is the role of inertia in keeping the earth in its orbit?

• It balances out the force of gravity.
• It keeps the earth stationary in its orbit.
• It pushes the earth away from the sun.
• It pulls the earth towards the sun.

What is the definition of hypothesis?

• The scientific law that states that every object in the universe attracts every other object.
• To develop an evidence-based idea that can be tested by experimentation or investigation.
• The tendency of an object to resist a change in motion.
• The attractive force between objects; the force that moves objects downhill.

What is the impact of the earth's tilt on the seasons?

• The earth's revolution around the sun.
• The distance between the earth and the sun.
• The earth's rotation on its axis.
• The earth's tilt of 23.5 degrees.
