Everything You Know About Planet Earth Is Wrong by Matt BrownThink you know the truth about how our world works? Matt Brown is here to blow away your long-held beliefs with his illuminating look at the many myths, legends, and misquotes that have shaped our perception of Earth.
Convinced Earth is round? It’s actually flatter at the poles. Think the Sahara is the biggest desert on the planet? It’s actually Antarctica. Matt Brown will astound you with some surprising truths about geography, nature, cities, and the people who live there. He guides you through a minefield of misinformation as he answers questions about whether we could solve overpopulation by colonizing space, why you shouldn’t measure earthquakes on the Richter scale, how the Mayans got it wrong when they predicted the world would end in 2012, and how a heatwave in 2003 led to a worldwide shortage of wine.
10 Things Everyone Should Know About Planet Earth
Here's everything you need to know about Planet Earth
Earth, our home, is the third planet from the sun. It's the only planet known to have an atmosphere containing free oxygen, oceans of water on its surface and, of course, life. Earth is the fifth largest of the planets in the solar system. It's smaller than the four gas giants — Jupiter , Saturn , Uranus and Neptune — but larger than the three other rocky planets, Mercury , Mars and Venus. Earth has a diameter of roughly 8, miles 13, kilometers and is round because gravity pulls matter into a ball. But, it's not perfectly round. Earth is really an "oblate spheroid," because its spin causes it to be squashed at its poles and swollen at the equator.
All rights reserved. Earth, our home planet, is a world unlike any other. The third planet from the sun, Earth is the only place in the known universe confirmed to host life. With a radius of 3, miles, Earth is the fifth largest planet in our solar system, and it's the only one known for sure to have liquid water on its surface. Earth is also unique in terms of monikers. Earth orbits the sun once every Since our calendar years have only days, we add an extra leap day every four years to account for the difference.
It's probably best that we don't think too much about the Earth. After all, it's a tiny orb spinning more than mph at the equator while simultaneously zipping through space at 67, miles per hour. But if you're feeling brave, here are a few things you might not know about Earth. The Earth orbits the Sun at approximately 93 million miles. As you probably know, at this distance it takes one year for the Earth to complete a revolution, and 24 hours to complete one rotation. The planet is about miles in diameter though the deepest we've ever drilled is 7. There are ,, cubic miles of water on the planet, which is enough that, if the water broke from the Earth and organized itself into a sphere, it would have a diameter of miles —about 40 percent that of the Moon.
In the range of solar system worlds, Earth is the only known home to life. Those are two reasons why astronomers and planetary scientists seek to understand more about its evolution and how it came to be such a haven. The name we use today, Earth , comes from Old English and German roots. It's not surprising that people thought Earth was the center of the universe only a few hundred years ago. This is because it "looks" like the Sun is moving around the planet each day.
