The earth is not flat but round.Give reason
Answers
Answer:
The earth is spherical planet and it's not round because as earth revolves around sun in circular orbit it should be spherical. also to form atmosphere on it it should be spherical
Answer:
Now that humanity knows quite positively that the Moon is not a piece of cheese or a playful god, the phenomena that accompany it (from its monthly cycles to lunar eclipses) are well-explained. It was quite a mystery to the ancient Greeks, though, and in their quest for knowledge, they came up with a few insightful observations that helped humanity figure out the shape of our planet.

Aristotle (who made quite a lot of observations about the spherical nature of the Earth) noticed that during lunar eclipses (when the Earth’s orbit places it directly between the Sun and the Moon, creating a shadow in the process), the shadow on the Moon’s surface is round. This shadow is the planet's, and it’s a great clue about the spherical shape of the Earth.

Lunar eclipse
A sequential view of the lunar eclipse that occurred on April 15, 2014. You can see Earth's shadow crossing the face of the Moon, and the shadow's shape is curved because Earth is spherical.Javier Sánchez
Since the earth is rotating (see the "Foucault Pendulum" experiment for a definite proof, if you are doubtful), the consistent oval-shadow it produces in each and every lunar eclipse proves that the earth is not only round but spherical—absolutely, utterly, beyond a shadow of a doubt not flat.
2. Ships and the horizon
If you’ve been next to a port lately, or just strolled down a beach and stared off vacantly into the horizon, you might have noticed a very interesting phenomenon: Approaching ships do not just “appear” out of the horizon (like they should have if the world was flat), but rather seem to emerge from beneath the sea.

But—you say—ships do not submerge and rise up again as they approach our view (except in Pirates of the Caribbean, but we are hereby assuming that was a fictitious movie series). The reason ships appear as if they "emerge from the waves" is because the world is not flat: It's round.
View of an ant walking on an orange
Ant on an orange
What you would see if you watched an ant crawling toward you over a curved surface.Moriel Schottlender
Imagine an ant walking along the surface of an orange, into your field of view. If you look at the orange “head on”, you will see the ant’s body slowly rising up from the “horizon” because of the curvature of the orange. If you would do that experiment with the ant approaching along a long road rather than a round object, the effect would change: The ant would slowly "materialize" into view (depending on how sharp your vision is).
3. Varying star constellations
This observation was originally made by Aristotle (384-322 BCE), who declared the Earth was round judging from the different constellations one
