Space volcanoes!!


We all know about volcanoes on earth, they are giant mountains that erupt at certain points in time to let out lava that destroys anything in its path. The reason lava destroys everything in its path is because it can go up to 1250 degrees Celsius, which is enough to burn anything on the surface of the earth. Volcanoes erupt because the magma ( molten rock) which lies under them, creates too much pressure and at one point, after storing up all that energy, it erupt and the magma comes out of the volcanoes. But volcanoes aren’t just on earth, and this makes sense considering that every planet has a molten hot core that needs to come out at some point to relieve all the pressure. Well we haven’t seen anything yet. The biggest volcanoes in our solar system is located on mars. It is called Olympus Mons, which is named after mount Olympus where the Greek gods reside. It is humongous, it is 14 miles tall (three times as tall as Mt.Everest, and 342 miles across (about half of Spain). So as you can imagine is tremendously huge. The last time it erupted was about 40 million years ago, and if it were to erupt again, it would be one of the most massive explosions ever seen by man. But luckily we live on earth where volcanoes like that aren’t even close to existence. But I hope one day we will see Olympus Mon erupt, the biggest volcano I our solar system.
