Aug 29, 2025 · How do we know Earth isn't flat? We can prove it. Here are 5 scientific ways of deducing that our home planet is a round globe, not a disc.

Jun 30, 2025 · The Earth is round because of gravity. During the planet’s formation, gravity pulled all matter equally towards its center, resulting in a sphere, the shape that distributes mass …

Mar 11, 2025 · They made the first orbit of Earth by sea, and they knew the Earth was round, allowing them to go across one ocean and come back home the other way. If the Earth were …

May 22, 2025 · It’s not a political decision or some technical mistake — it’s because the Earth is a rotating sphere. As the Earth spins, different parts of it face the Sun at different times, creating …

Jan 16, 2025 · Explore the science behind Earth's shape. Learn why our planet is a sphere (or almost!) and the forces that shaped it, from gravity to rotation.

Mar 9, 2025 · Earth’s rotation explains why Earth isn’t a perfect sphere. The rotational force creates a slight bulging at the equator, forming the oblate spheroid shape.

Mar 10, 2009 · And that's why the 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 …

This shape is caused by the sheer speed of Earth’s rotation, which makes our planet about 70,000 feet wider at the Equator than at the poles. The Moon’s gravitational pull on the tides …

Students will learn: • Why Earth looks round from space • How gravity causes Earth to bulge at the equator • What the term geoid really means • How ancient and modern scientists proved ...

Nov 16, 2023 · Satellite images and measurements of Earth's gravitational field show us that the Earth is not a perfect sphere. Instead, it is an oblate spheroid shape. An oblate spheroid is a …
