the shape of continents of Earth the effect of storms and hurricanes forces changing the surface of Earth planets and moons in the solar system
I gave my students this multiple choice question: The first powerful telescopes were built during the early 1600s. Scientists at that time were able to learn more about which subject by using the telescope?

Only one answer is correct among these 4 choices:
- the shape of continents of Earth
- the effect of storms and hurricanes
- forces changing the surface of Earth
- planets and moons in the solar system

Could you tell me which one is correct?

planets and moons in the solar system
