Which statement describes the motion of Earth around the sun? Options: The speed of Earth is constant regardless of its distance from the sun., The speed of Earth is constant because the distance remains the same between Earth and the sun., Speed Increases the farther Earth is from the sun and decreases the closer it is to the sun., Speed increases the closer Earth is to the sun and decreases the farther it is from the sun.

Back

Speed increases the closer Earth is to the sun and decreases the farther it is from the sun.

How does a straight alignment between Earth, the sun, and moon impact the tides on Earth?

Back

It produces the greatest change in high and low tides.

Front

Which describes the difference between nuclear fission and nuclear fusion?

Back

Nuclear fission splits a heavier nucleus into smaller nuclei, and nuclear fusion is the process that produces the radiant energy of stars.
