Home sweet home! Our home planet Earth has always been an interesting topic when it comes to space or solar system lessons. Earth as we know it, so far is the only planet in our Solar System that is known to harbor any lifeforms and the only one naturally suitable to sustain life. The following are amazing facts about earth you cannot miss.
Earth is the only planet not named after a god
Differing from other seven planets within our solar system which are all named after Roman gods or goddesses, Earth got its name from English and German words which basically signifies the ground. The term Earth is inferred from Old English and German words encompassing eor(th)e/ertha and erde respectively; both words mean the ground. But the one who came up with this term is yet to be revealed for hundreds of years.
Most of the Earth’s surface is covered in water
70% of our planet is covered with oceans while the rest stands out as the solid ground, soaring above sea level sustaining civilization. Among the major surface on earth, only 3% water of the earth is fresh while the rest is salted. Of that particular amount of fresh water on earth, over 2% is frozen in ice sheets and glaciers; it means that approximately 1% fresh water which is available for human’s main consumption is contained on rivers, lakes and underground.
Earth is the Only Planet Known to Support Life
Despite all the fascinating stories saying that the are opportunities to support life outside the planet Earth, driven from the discovery of evidence leading to ancient ocean on Mars surface and the finding of liquid material on Titan which have never failed to fascinate scientist for being one of the most Earth-like worlds that have been found, we have to deal with the fact that the only home we can dwell is our blue planet, the Earth.
But if there is any possibility of other planets which can lead us to interplanetary living, scientists are working on experiments that will help us to make it happen. As an example, NASA has launched several space missions which include the development of the Nexus for Exoplanet System Science (NExSS), Mars Exploration Rover (MER) mission sending to rovers Spirit and Opportunity to the red planet followed by Mars Science Laboratory mission (MSL) sending the latest and more advanced rover which still remains up until now. The search for our second home continues.
The highest point on earth is located on mount Everest
Reaching 29,035 feet above sea level, the peak of Mount Everest is declared as the highest point on earth. Reinhold Messner is known for his action reaching mount Everest for the first time in 1978. He conquered the Earth’s highest point without any supplemental oxygen, in other words, he has overcome all the possible ‘threat’ told by scientist saying that a human would not be able to survive on certain height, which has been recorded as Death Zone on 26,000 feet above see level. Many hikers followed ever since, making him the pioneer of the highest spot on Earth.
The lowest point on Earth is called Challenger Deep
The deepest or lowest known point on the Earth’s seabed hydrosphere is called the Challenger Deep; it reaches the depth of 35,755 to 35,814 feet by forthright measurement from submersibles and more by sonar bathymetry. The Challenger Deep is located in the Pacific Ocean, at the southern end of the Mariana Trench near the Mariana Islands group.
