What are the three evidence that the earth is not flat in shape?

Answer 1

1. Gravity and the Earth's curvature: Gravity pulls objects towards the center of the Earth, which causes the Earth to have a spherical shape. If the Earth were flat, then the force of gravity would be stronger in some areas and weaker in others, which is not the case. Additionally, the Earth's curvature can be observed in various ways, such as the way ships disappear over the horizon, the changing angle of the sun and stars at different locations, and photos from space.

2. Satellite images and astronomical observations: Images taken from space clearly show that the Earth is round, not flat. Astronauts in space have consistently reported seeing a spherical Earth. Furthermore, the orbits of satellites and the International Space Station depend on the Earth's round shape and its gravitational pull.

3. Airplane flights and time zones: If the Earth were flat, airplanes would be able to fly in straight lines between any two points on the planet, but this is not what happens in practice. Flight paths are based on the Earth's curvature, which allows for more efficient travel. Additionally, the existence of time zones also suggests that the Earth is round, as the sun's position and the time of day change as you move across the Earth's surface.
