Volcanoes, the Dangerous Landform
They are a dangerous but amazing sight. Magma flowing in and out with a bright color. Mountains? No, these landforms unleash their magma violently but when not, they are calmer than the ocean. Volcanoes. Why do they erupt, how are they formed, that’s some of the things that make them fascinating, what make them truly unpredictable.
Volcanoes are landforms with rather similar forming to mountains, with tectonic plates; The gigantic chunks of crust that move constantly but over time by convection currents; the hottest places in the mantle which was first suggested by Alfred Wegener, a geology scientist. The plates were formed more than 900 million years ago after the earth being at blazing temperatures, cooling down. That made the Earth’s crust shrink and crack. Which is what made what we now call the plates. For a volcano to be formed there would have to be 2 types of plates; An Oceanic Plate and a Continental plate; An Oceanic plate is a plate that’s thin (9-15 miles) and most of the plate is underwater while Continental Plates are thick (20-50 miles) and hardly anything underwater. The Oceanic Plate, because it is thinner, would have to go under the Continental Plate and bits of the Oceanic Plate would make huge mounds. The mounds would start looking into a mountain-like landform. The Oceanic Plate would later reach the mantle and melt. Even later small vents would form that lead to the surface to the peak and around of the mountain-like landform, making it a volcano. This process takes thousands of years. Volcanoes can go extinct in a few hundred centuries. While they’re active, they can be dangerous.
Some volcanoes need and oceanic plate and a continental plate, but some have a different forming; by a hole around the middle of an oceanic plate. That holes is formed by an even hotter area in the mantle. (This area is called a hotspot) This makes a hole. From that hole would come magma cooling down quickly, (because this happens underwater) Making it turn solid, but more magma would come out making it gradually a mount that keeps growing. But the oceanic plate is moving, so at some point the volcano will stop growing and a volcano next to it will start growing. And will happen the same thing over again until the plate moves from the hot spot.
LOCATIONS OF THEM
Volcanoes are found around the borders of continental plates and oceanic plate (where they collide) and even in the middle of an oceanic plate. Most volcanoes that are known are on land but many are under water (most are on land because they are easier to find).
Volcanoes are landforms with a crater where the peak should be. . That is where boiling magma comes out. When a volcano erupts the magma that goes out is then called lava. Sometimes when a volcano erupts it could basically remodel the top half of the volcano.
MOST FAMOUS VOLCANO
Mount Vesuvius is one of the most famous volcanoes, killing 2000 people in 79 AD, wrecking 3 cities.
What would happen in the future? I think that the volcanoes we now have will stay active, dormant, or extinct. And new ones will come to life. Constantly as well as some going extinct at the same time.
