Trees may have more to them than meets the eye. Their roots are thought to be interwoven underground, forming a massive network that may be visually likened to the human nervous system. This network, according to experts, allows trees to communicate and aids in their behavior, defense, learning, and memory.

The ocean continues to be one of the most enigmatic and perplexing things to humanity. No matter how much we learn and tell about it, there is still much more to learn and reveal since we have only explored one-fifth of it. With a total volume of 1.35 billion cubic kilometers, it is safe to assume that we have a long way to go before we can unravel the endless mysteries that this mystery may be hiding.

According to a scientist from the University of Maryland, our globe used to be purple. Instead of chlorophyll, ancient microorganisms might have used different chemicals to digest sunlight. Because these chemicals may give microorganisms a purple hue, the entire planet might have been purple.

According to Water in Crisis: A Guide to the World's Fresh Water Resources from the United States Geological Survey, the seas hold slightly more than 96 percent of the total amount of water on the planet (USGS). However, that is mostly seawater. You must go to the poles to find the majority of the world's freshwater, as 68.7 percent of it is buried in ice caps, permanent snow, and glaciers.

The Arctic is largely made up of ocean, while Antarctica is mostly made up of land. While both are covered in sheets of ice, the water beneath the Arctic ice cap (which lies just about a foot above the sea) may retain heat and assist warm the surrounding air. According to Scientific American, "the surface of the ice sheet at the South Pole is more than 9000 feet in elevation—more than a mile and a half above sea level" in Antarctica. (Of course, higher elevations result in cooler temperatures.) The North Pole's average summer temperature is 32°F. It is -18°F at the South Pole.

Our oceans cover more than 70% of the Earth's land surface. With the ocean covering so much of the Earth's surface, it's clear how important these marine environments are to the planet and how much more there is to be discovered.

Aquatic life accounts for the vast majority of life on Earth. Because the oceans cover so much of the Earth's surface, it's no surprise that marine species outnumber those on land. However, the oceans are home to an astounding 94% of all living species on Earth.

The world's longest mountain range is submerged. The Mid-Ocean Ridge, the Earth's longest mountain chain, is almost entirely beneath the ocean and stretches for 65,000 kilometers. This mountain chain is said to be less explored than the surfaces of Venus or Mars.

Around half of the United States is submerged underwater. Not only does a large portion of the planet exist beneath the ocean, but so does the United States – roughly half of it.

Humans can only use a small portion of the water on Earth. We were taught in school that water covers the majority (71 percent) of the planet's surface. While this is true, according to National Geographic, humans can only use 0.007 percent of that water. This is due to the fact that only about 2.5 percent of the water on Earth is fresh water, and only 1 percent of that is accessible. The remainder is made up of glaciers and snowfields.

There is enough gold within Earth to cover the planet. According to Discover Magazine, there's a lot of gold on—or in—our planet: 99 percent of the precious metal can be found in the Earth's core. How much do you have? Enough gold to cover the entire Earth's surface in 1.5 feet of gold.

Prototaxites, a mysterious genus of creatures that lived between 420 and 370 million years ago, grew large trunks up to 3 feet (1 meter) wide and 26 feet (8 meters) tall. Scientists debated whether these were strange ancient trees for a long time, but a 2007 study concluded that they were fungi, not plants. In 2007, study author and paleobotanist C. Kevin Boyce told New Scientist, "A 6-meter fungus would be odd enough in the modern world, but at least we are used to trees quite a bit bigger."

Apple's initial iPod included a small Easter egg. This game could only be accessible if you knew the correct sequence of buttons to press. "Go to the 'Around' menu and hold down the center button for about three seconds to play a Breakout (Pong) game while you listen." Breakout, the hidden game, is significant in Apple's history since it was a product on which both Steve Jobs and Steve Wozniak collaborated at Atari.

Richard and Maurice McDonald both the company's founders established and occupied a hot dog stand near the Santa Anita racecourse in Arcadia, California, the USA in the late 1930s. They launched a drive-in barbecue restaurant in San Bernardino, California, in 1940, which they converted into a burger establishment in 1948. Maurice and Richard McDonald owned the world's ninth-largest economy, with 27 billion dollars in income from McDonald's franchisees.

The longest novel which exists is ‘In Search of Lost Time’ by Marcel Proust. This masterpiece has made its mark and left its essence in the Gunnies Book of World Records. The whole novel is contained in 13 volumes clocking up nearly 1.3 million words. Isn’t this amazing?

Have you ever heard about Pangram? Pangram in the English Language is a sentence that contains every letter in the language. Sounds interesting? Isn’t it. One of the best examples of Pangram is ‘The quick brown fox jumps over the lazy dog’. The sentence has every letter and hence is a pangram. Can you think of some more Pangrams?

It might come to you as a matter of surprise, but kakapo, the world’s largest parrot, can not fly. Kakapo can grow up to two feet and can weigh up to nine pounds. Kakapo is the only flightless parrot in the world. But that’s not the only interesting fact about the world’s largest parrot. Kakapo is also the only parrot that is active at night.

Every book has its own worth. But the most expensive printed book in the world is the 1640 Bay Psalm book. The book is from America and was sold in 2013, in November, for USD 14.2 million.

In India, there are more vegetarian options and consumables influenced by Indian food on the McDonald's menu. The Veg Pizza McPuff, Maharaja Mac (select veg or chicken), McAloo Tikki (potato patty), McSpicy Paneer (cheese patty), and Masala Grill Veg are some of the distinctive Indian McDonald's options.

Yes! You read that right. Parrots have zygodactyl feet. Parrots' feet are much like human hands that they use to pick up their food and bring it to their mouth. They have one of the strongest feet among all the birds, which they use to clench branches for a long period. The strong feet even allow these birds to hang upside down from the branches.

Have you ever thought about why snakes put out their tongues? They're probably trying to smell their surroundings with their tongue. They have a Jacobson's or vomeronasal organ on the roof of their mouth. The odor then travels from the tongue to an organ in their mouth. Their odor is particularly pleasant and has been characterized as smelling in stereo. They have a long tongue and numerous sensors that can detect varying levels of chemical stimuli.

According to Merriam-Webster, the "octo" prefix alludes to the eight points on the popular sign, but the "thorpe" remains a mystery. One hypothesis derives from the Old English term for "village" because the sign resembles a hamlet surrounded by eight fields!

Snakes are commonly labeled "cold-blooded," although this is false because their blood is not chilly. The correct phrase is ectothermic, which means their body temperature is variable and controlled by external factors. Unlike mammals and birds, Reptiles cannot regulate their body temperature internally and therefore rely on heat sources such as the sun to warm up.

Elephants, the largest land animals, consists of around 150,000 units of muscle units in their trunk. Trunks of the elephants are considered the most sensitive organ found in any mammal. Asian elephants have been found to pick up a peanut, shell it, blow the shell out and eat the nut. Moreover, Elephants use their trunks to suck the water, and a trunk can contain up to 8 liters of water. Isn't this amazing?
