15. The Center of Universe:
Earth Was Once Believed to be the Center of the Universe Although it may not feel like we are moving, Earth is constantly in rotation. The geocentric model was first presented by ancient astronomers, due to the fact that the Sun and other celestial plants seemed to move while Earth stayed still. Ancient astronomers or scientists would even be punished when trying to disprove the model. Today, we do know that Earth and other planets revolve around the Sun. This is called heliocentrism. In fact, we are moving around the Sun at 67,000 miles per hour.le’s mineral contain an ocean. Although, it is not a liquid type of water, bound within the minerals existing in extreme pressure.
14. Earth’s Rotation is Decreasing:
The Earth’s rotation is slowing down gradually. Approximately seventeen milliseconds per hundred years, although the planet’s rate is not perfectly calculated. The Earth rotates from the western hemisphere towards the eastern hemisphere. Although, if viewed from the North Star, the Earth turns counter-clockwise. At Earth’s equator, its speed is about 1,000 miles per hour. For now it deceleration has no huge impact, except that it has the effect to lengthen our days. Not to worry, because it happens at such a slow rate, that it could be at least 150 million years before the length of a day will become 25 hours.
13. Earth is the largest terrestrial planet:
Our solar system has four terrestrial planets, which are Mercury, Venus, Mars and Earth. Terrestrial planets are made up mainly of metals or silicate rocks and are composed of the same structure.The Earth is mostly oxygen, iron and silicon. Most the iron is actually found at the core. Planet Earth is the largest terrestrial planet in the solar system and the only planet known to have an active hydrosphere. Earth is also the densest planet in the solar system . the average density depends on a planet’s composition. The average density of our planet is approximately 5.52 grams per cubic centimeter.
12. Earth is ancient:
By ancient, I mean that Earth is 4.54 billion years old . Scientists and researchers are can determine Earth’s age by dating the oldest rocks and meteorites on the planet. The Earth is so old, that the ground you’re walking on is recycled. Earth’s rock transforms igneous rocks to sedimentary rocks to metamorphic rocks. Researchers gather the tiny fragments of these rocks. Early age calculations of Earth have been dated back to 1862 and have been debated for a number of years. After oceans had been determined to be about 80 to 100 million years old, it was speculated that Earth was very much older.
11.The Oldest Things on Earth are still alive today
We already know Earth is 4.54 billion years old, but it’s crazy to think that some of the earliest inhabitants of Earth are still alive today. These organisms are shown to be thriving for thousands of years and don’t show any sign of extinction. Some of these inhabitants include Posidonia Oceanica seagrass. It’s estimated to be over 100,000 years old and is located in the warm waters of the Balearic Islands in Spain. Stromatolites are also ancient bacteria, which is believed to be one of the first kinds of life to evolve. This type of bacteria can live anywhere from two to three thousand years.
10. Rocks on Earth can move
It’s a geological phenomenon also called sailing stones or rolling rocks. Rocks have been observed to move and create long tracks without the aid of animals or humans. Rocks vary in size, and even boulders have been found to move . Trails of sliding rocks can travel in the same direction or suddenly change its track. Scientists have studied these rocks in various locations, such as Death Valley and Little Bonnie Claire Playa in Nevada. Thanks to a mixture of rain, wind, sun and ice; conditions have to be certain for rocks to move. Scientists have even strapped GPS units on the rocks to keep track of how far they will travel.
9. Earth has a Boiling Point
The Earth has multiple layers. It starts with the crust, mantle, outer core and inner core and we are digging to the very center of the Earth . Or attempting to at least. To make it short, it gets very hot, very quickly the closer you get to the center of the Earth. The Earth’s crust, which is the outer shell reaches down thirty miles and the temperature increases at least 77 degrees Fahrenheit per kilometer. So once you’re ten kilometers down, temperatures could reach a scorching temperature of 482 degrees Fahrenheit. It’s not entirely sure how hot Earth’s inner core can be, but it is believed to around 10,300 degrees Fahrenheit .
8. Lut Desert is the Hottest Place on Earth
Seven years of satellite temperature data indicates that the Lut Desert located in Iran is the hottest place on the planet. From 2005 to 2009, the Lut Desert reached a high temperature of 159.3 degrees Fahrenheit. Although the Lut Desert had the highest overall temperature, it was not the hottest spot every year. The second highest temperature in a seven year analysis was 156.7 degrees Fahrenheit in the shrubland of Queensland. The third hottest temperature was in 2008, when the Flaming Mountain was recorded to be 152.2 degrees Fahrenheit.
7. Antarctica is the Coldest Place on Earth
It’s no surprise that Antarctica is the coldest place on Earth. Vostok is a Russian research station based in Antarctica, which was said to have the lowest temperature ever recorded on earth at 89.2 degrees Celsius. This temperature is way below the freezing point of the carbon dioxide in the air itself. Meanwhile, Oymyakon Russia is the coldest inhabited place on Earth. Temperatures there have reached a freezing point of 67.7 degrees Celsius.
6. Longest Mountain Range is Underwater
The longest mountain range in the world is actually underwater. It is the Mid-Atlantic ridge and stretches for 80,000 km around the world. It has an average spreading rate of about 2.5 centimeters per year. This is 20 times longer than the longest range on the surface of the Andes mountains and is completely volcanic. It includes a deep rift valley that runs along the axis of the ridge.
5. Challenger Deep
It is the home to the deepest location ever known to mankind. It measures 2550 kilometers long and 69 kilometers wide and is located in the Pacific Ocean. Throughout history, it was only explored on four occasions which includes director James Cameron. The unworldly environment includes odd vents that excrete liquid carbon dioxide and giant amoebas that surprisingly can adapt to high pressure. A new species of microbial life forms were found thriving inside rocks 1900 feet below the seafloor, under 8500 feet of ocean.
4. Earth has hidden Oceans
Seventy percent of Earth is covered in oceans, but humans have only explored 7 percent of it. There is so much more to uncover, and Earth’s interior is way more complicated, considering the possibility that an ocean of water is hidden in Earth’s mantle. An analysis of seismic waves passing through Earth shows that 400 miles below the mantle indicates the possibility of it holding such huge amounts of water. The underground water is hidden in a blue rock named “Ringwoodite”. It acts like a sponge containing water and hydrogen. It said to have as much water to fill the oceans three times.
3. Earth doesn’t take 24 hours to rotate on its axis:
Even though there are 24 hours in a day, it only takes 23 hours, 56 minutes and 4 seconds for the Earth to rotate completely. Now this doesn’t mean a day is four minutes shorter than we think. Every day, the Sun moves in comparison to the background stars about 1 degree. When you add up the motion of the Sun that we see, as well as its axis, then it would equal to 24 hours.
2. A year on Earth isn’t 365 days
It’s 365.2564 days. We create a leap year every four years to consolidate for the extra .2564 days. After four years, the calendar is a day, so adding an extra day keeps the calendar balanced. Each leap year has 366 days instead of the usual 365 days by extending an extra day in February. The only exceptions to this rule is if the year is divisible by 100. For example, 1900 or 2100. Unless it is divisible by 400, like 1600 or 2000.
1. Earth is the only known planet with life:
As of now, Earth is the only known planet to have proven life forms. Other planets like Pluto have ice and water, although it is too far from the Sun to have life. Other planets also have oxygen in their atmosphere but are too close to have surviving life. With more than thousands of unexplored planets, there may be habitable zones within them. It’s scary to think that we are alone in the universe, but yet it is also scary to think that we are not alone. In time, we can only hope to contact the extraterrestrial world that exists beyond our means, unless they contact us first.
