Yes, before modern technology, it was easy to get lost at sea without the stars to guide them. Astronomy helped explorers find their way safely.

Question 10

Did people use the sun for navigation?

Accepted Answer

Yes, people used the sun to tell time and direction. By knowing where the sun rises and sets, they could figure out east and west.

Question 11

What are constellations?

Accepted Answer

Constellations are groups of stars that form pictures or patterns in the sky. Sailors used them to recognize different parts of the sky while navigating.

Accepted Answer

Over time, new tools and better maps made navigation easier and more accurate. Today, we use GPS, which is much faster and simpler than using stars.

Question 16

Did stars help people on land too?

Accepted Answer

Yes, travelers on land also used stars to find their way, especially in deserts and wide open spaces without roads. Stars helped guide them just like at sea.

Question 18

What is the horizon?

Accepted Answer

The horizon is the line where the Earth and sky seem to meet. Sailors watched the horizon to measure star angles for navigation.

Question 19
