How do we know Earth isn’t flat? For thousands of years people have known Earth is round. Ancient civilizations used the stars and shadows to figure it out. Mariners confirmed it by sailing around the globe. And when the space age began, we saw it with our own eyes — Earth is round! A NASA scientist explains how we’ve known for centuries that our planet is a sphere. Explore more: https://go.nasa.gov/4kITBXo | NASA Earth

Why is the Earth a Sphere?

This is why the Earth isn’t a perfect sphere. 🌍 Now, don’t get too excited, we’re not saying it’s flat, but it does bulge at the equator (it’s an ‘oblate spheroid’!), because when things spin, they tend to flatten out. This is also why our solar system is all in one flat plane. As the big molecular cloud that formed our sun and planets started to condense, it was spinning faster and faster, meaning that all the matter flattened out into one disc. | Royal Institution of Great Britain

The Earth’s Spheres - Comparing Land, Air, Water & Life🌏 What you’re seeing is Earth in layers: first the geosphere (all the solid land and rocks), then the atmosphere (all the air surrounding Earth), the hydrosphere (all water-oceans, rivers, and lakes), and finally the biosphere (all living things). This animation shows how massive each sphere is and how they interact to make our planet habitable.💧🌴🌌 #nasa🚀 #earth #space #milkyway #solarsystem #universe #science #education | Spaceastrover
