Question

State three reasons to show that the earth is spherical

Answer 1

Explanation:

number one. We know the earth is round because we have photographic evidence.

Number two. During a lunar eclipse, the shadow of the earth on the moon is curved.

Number three.Ferdinand Magellan and many people afterwards circumnavigated the earth. That means he left headed west, continued going west, and came back to where he started still going west. Actually Magellan was dead, but one of his ships led by Juan Sebastian Elcano finished the journey. If you head west and circumnavigate the earth yourself, you'll be able to tell because you will observe one fewer sunrise than everyone who stays at home.
