Interesting Facts About Earth And More
Most of us know general facts about Earth, but we do not really think about them. This is because we do not really care or because there are many things about Earth that we do not know about. For example, did you know that the Earth is the only planet in the Solar System that actually has plate tectonics? These plate tectonics are actually parts of the Earth's crust, which can float and collide, causing earthquakes and changes in the look of the crust.
One of the most interesting facts about Earth is that we think it is a sphere, but in reality it not a sphere per say. It's because the rotation of the Earth makes the equator to be bigger than it should. When considering facts about Earth, most of us have no idea that the Earth rotates around its axis in 23 hours, 56 minutes and 4 seconds, which means that it's going to take our planet practically a day to complete this action.
Everyone knows that the Earth has a natural satellite, the moon, but not many are aware that we also have two co-orbital satellites near planet earth. At the same time, how many of us realize that 70 percent of the Earth is covered with water? It's known that many of us also call our planet the Blue Planet but this name was used when our astronauts first decided to go into space. These days, thanks to pics of Earth, we can all find out exactly why our planet is named this way.
Due to the plate tectonics, Earth is the only planet from our Solar System that can actually have earthquakes and volcanoes. Yet another fascinating fact about Earth is that from a distance it seems to be the brightest planet from our Solar System. This occurs because the light of the sun gets reflected off the huge amounts of water present on planet earth.
Another interesting fact is that unlike all other planets from our Solar System, that happen to be named after mythological gods, ours is simply known as Earth or the Blue Planet. We constantly complain about not having a sufficient amount of time to do everything we have to do, but according to scientists, in a few million years, a day will have around 27 hours. Are you aware that the Earth is the only planet in our Solar System that has water in all of its three states of matter? We certainly have ice, which is solid, water, rain, which are liquid and clouds, that are gas.
