Alien worlds may be all the rage, with their mystique and promise, but the orb we call home, planet Earth, has all the makings for a jaw-dropping blockbuster movie: from the drama of explosive volcanoes, past meteor crashes and catastrophic collisions between rocky plates to the seeming fantasy of the ocean’s deep abysses swirling with odd life and tales of the coldest, hottest, deepest, highest and all-out extreme spots. Here are more interesting facts about the world.
Did you know Earth is not actually a sphere? That we are rocketing around the sun at 67,000 mph? That the majority of Earth’s fresh water is locked up in Antarctica?
Here Are Some More Interesting Facts About The World
We’re the third rock from the sun
Our home, Earth, is the third planet from the sun and the only world known to support an atmosphere with free oxygen, oceans of liquid water on the surface and — the big one — life. Earth is one of the four terrestrial planet: Like Mercury, Venus and Mars, it is rocky at the surface.
Keep reading to find out why Earth is not a sphere, even though it is often said to be.
Earth is a squashed sphere
Earth is not a perfect sphere. As Earth spins, gravity points toward the center of our planet (assuming for explanation’s sake that Earth is a perfect sphere), and a centrifugal force pushes outward. But since this gravity-opposing force acts perpendicular to the axis of Earth, and Earth’s axis is tilted, centrifugal force at the equator is not exactly opposed to gravity. This imbalance adds up at the equator, where gravity pushes extra masses of water and earth into a bulge, or “spare tire” around our planet.
Continue on to find out how big Earth’s waistline is.
The planet has a waistline
Mother Earth has a generous waistline: At the equator, the circumference of the globe is 24,901 miles (40,075 kilometers). Bonus fact: At the equator, you would weigh less than if standing at one of the poles.
Keep going . . . you’re going to be surprised to learn just how fast you are moving right now.
Earth is on the move
You may feel like you’re standing still, but you’re actually moving — fast. Depending on where you are on the globe, you could be spinning through space at just over 1,000 miles per hour. People on the equator move the fastest, while someone standing on the North or South pole would be perfectly still. (Imagine a basketball spinning on your finger. A random point on the ball’s equator has farther to go in a single spin as a point near your finger. Thus, the point on the equator is moving faster.)
And, as you’ll learn on the next slide, we’re also racing around the sun at an incredible speed.
The planet moves around the sun
Oh yeah, and the Earth isn’t just spinning: It’s also moving around the sun at 67,000 miles (107,826 km) per hour.
Earth is old
Researchers calculate the age of the Earth by dating both the oldest rocks on the planet and meteorites that have been discovered on Earth (meteorites and Earth formed at the same time, when the solar system was forming). Their findings? Earth is about 4.54 billion years old.
The planet is recycled
The ground you’re walking on is recycled. Earth’s rock cycle transforms igneous rocks to sedimentary rocks to metamorphic rocks and back again.
The cycle isn’t a perfect circle, but the basics work like this: Magma from deep in the Earth emerges and hardens into rock (that’s the igneous part). Tectonic processes uplift that rock to the surface, where erosion shaves bits off. These tiny fragments get deposited and buried, and the pressure from above compacts them into sedimentary rocks such as sandstone. If sedimentary rocks get buried even deeper, they “cook” into metamorphic rocks under lots of pressure and heat.
Along the way, of course, sedimentary rocks can be re-eroded or metamorphic rocks re-uplifted. But if metamorphic rocks get caught in a subduction zone where one piece of crust is pushing under another, they may find themselves transformed back into magma.
Our moon quakes
Earth’s moon looks rather dead and inactive. But in fact, moonquakes, or “earthquakes” on the moon, keep things just a bit shook up. Quakes on the moon are less common and less intense than those that shake Earth.
According to USGS scientists, moonquakes seem to be related to tidal stresses associated with the varying distance between the Earth and moon. Moonquakes also tend to occur at great depths, about midway between the lunar surface and its center.

Alaska had the largest earthquake
As of March 2016, the largest earthquake to shake the United States was a magnitude-9.2 temblor that struck Prince William Sound, Alaska, on Good Friday, March 28, 1964. (Photos shows the Four Seasons Apartments in Anchorage, a six-story lift-slab reinforced concrete building, which cracked to the ground during the quake.) And the world’s largest earthquake was a magnitude 9.5 in Chile on May 22, 1960, according to the U.S. Geological Survey (USGS).
The hottest spot is in Libya
The fiery award for Earth’s hottest spot goes to El Azizia, Libya, where temperature records from weather stations reveal it hit 136 degrees Fahrenheit (57.8 degrees Celsius) on Sept. 13, 1922, according to NASA Earth Observatory. There have likely been hotter locations beyond the network of weather stations. (The image was created from data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite.)
