Example Questions

Example Question #1 : Describe The Motion Of Objects In The Universe

Which of the following is the primary reason we experience night and day on Earth?

Possible Answers:

Earth revolves around the sun

the sun revolves around Earth

Earth rotates

the sun rotates

Correct answer:

Earth rotates

Explanation:

Stars, planets, moons, and other objects in space orbit around each other due to gravity. This type of motion is called revolution. Many objects in space also spin in place. This motion is called rotation.

One Earth rotation is the length of an Earth day and is the reason we experience night and day. One Earth revolution around the sun is the length of a year. Other planets have different lengths of days and years because they rotate and revolve at different speeds.

All planets in our solar system revolve around the sun in the same direction. Most of them (with the exception of uranus and venus) rotate in the same direction as well.About half of the galaxies in the universe rotate clockwise, and the other half rotate counter clockwise. Scientists think this may be because of the way our universe began.

Example Question #6 : Describe The Motion Of Objects In The Universe

When examining galaxies outside our own, we notice that they are "red-shifted." This means that these galaxies are moving away from the observer. How does this observation support the Big Bang Theory?

Possible Answers:

It suggests our galaxy was the first one to form.

It indicates that the universe is expanding.

It shows that the Earth is spinning.

It means the Earth is the center of the universe.

Correct answer:

It indicates that the universe is expanding.

Explanation:

The answer is "It indicates that the universe is expanding."
