• Standing on that equator you would be spinning around Earth’s center at 1000 miles per hour. At the poles, however, you would be standing still
• The rocks you are standing on get recycled. Volcanoes spit them out as magma, they dry, harden, and after a very long time either gets sucked down again by plate tectonics or get pushed towards Earth’s core by a fresh layer of rocks above.
• Earth is the only planet in the Solar System with plate tectonics.
• Thanks to modern astronomy and space travel, scientists have since come to understand that the Earth is actually shaped like a flattened sphere.
• The hottest temperature ever recorded on Earth’s surface was 136 degrees F or 57.8 degrees C in El Azizia, Libya recorded in 1922.
• Gravity is not distributed equally. Places like Hudson Bay in Canada actually have less gravity than other regions of the globe. This is due to the fact that there is less land mass in that part of the planet thanks both to retreating glaciers on the surface and swirling magma deep in the core
• Earth’s magnetic North Pole is moving northward at a rate of 10 miles per year
• Scientists believe Earth may have had two moons at one point in time.
• The longest mountain range on Earth is actually underwater. It is called the mid ocean ridge system. It stretches for 80,000 km all around the world and is nearly 20 times longer than the longest range on the surface, the Andes Mountains. Not only that, the whole thing is completely volcanic.
• The Earth is the only inner planet (Mercury, Venus, Earth and Mars) to have one large satellite, the Moon
• Earth’s got a heartbeat that can be felt in space. The beat is a quasi-standing electromagnetic wave that beats fundamentally at around 8 cycles per second.
• Antarctica — our southernmost and oft-forgot continent — holds 70% of Earth’s fresh water and 90% of its ice. It’s got more ice than the Atlantic Ocean has water, so it’d be very bad news if it were to melt.
• The Stromboli Volcano has been erupting continuously for the past 2,000 years. It’s on a small island off Sicily’s northern coast in the Tyrrhenian Sea, so it doesn’t usually bother anyone too much. As another fun fact, this volcano inspired J.R.R. Tolkien’s Mount Doom.
• Coral reefs boast the planet’s highest density of life, even more than rain forests. They’re teeming with all kinds of creatures, and among them is the coral itself. Coral is the world’s largest living structure, and some reefs can even be seen from space.
• Everyday about 100 tons of interplanetary material falls down onto Earth’s surface primarily from the ice of comets as it vaporizes near the sun.
• The magnetic North and South poles of the earth gradually flip flop about every 2 lakhs to 3 lakhs years.
• It takes about 8 minutes and 19 seconds for light to reach Earth from the sun. This is due to Earth’s distance from the sun.
