It must be at grade five or something so you must have read earth to be round. Of course earth is round. And, this concept came from the Greek Civilization. Except for the Flat Earth Society, the science asserts earth to be round at all which is of course a truth. If you look into this MinutePhysics, you will be given with ten reasons why earth is round.
Of course, the Earth isn't perfectly round. Because it’s turning on its axis approximately once every 24 hours, the Earth’s equator bulges outwards. The same effect of which you have your weight different at different places. Because weight (w) = mass (m) * acceleration due to gravity (g), and the value of g is inversely proportional to the radius of the earth. The radius of the earth at the equator is more than that of the poles. Hence, you have your weight more at the polar regions. This conversely suggests that the earth is spherical, one of the round structure of course.
Also, when an object has the gravity to pull itself into a sphere, astronomers say that it’s in hydrostatic equilibrium. And that’s why the Earth is round.
Hence, earth is round. Aren't you convinced?
See these still images from NASA, which cannot be wrong and hypothetical at all.
