What is magma?
When you stand on solid ground, it is difficult to think of a planet like anything other than a very solid rock. Yet this is not the case. Several kilometers below the Earth's peel, the hard rock is replaced by a softer rock and then eventually the liquid rock of gases and minerals that sometimes exploded from volcanoes or cracks on the ground.
You wouldn't want to be close to this molten rock because it has an extremely high temperature. Although several materials melt at temperatures of about 1100 degrees F (593.33 ° C), most of the magma under the Earth's bark maintain temperatures between 1292 and 2372 ° F (700-1300 ° C). When the molten rock explodes or flows to the Earth's surface, it quickly loses thermal energy, even if it is still much warmer than it would expose it.
Some scientists distinguish between magma and lava and define lava as a molten rock that is on the earth's surface or above the Earth's surface. This can also be called extrusive . Another way to budets on the remains of molten rocks above the ground, except lavaFlows are when you explore Igneous Rock. All igneous rocks are made of magma and some rocks are similar to the liquid flow that produced them. For example, obsidian is glossy and fragile and somewhat resembles the flow of certain types of magma. It is actually a naturally occurring glass that gains its shine and smoothness from the fact that Magma did not crystallize as it has cooled.
Another interesting ignited rock created by one molten rock is a pumice, which is very light, so light that it will float in most fluids. Unlike the smooth gloss of obsidian, the pummy resembles natural sponges with a number of characters. They are caused when gases create bubbles in a rock that do not have time to reform before cooling. This results in a bubbling appearance of the pumice and its low density.
What does magma create? The tag immersion further in the earth's strata increases pressure and pressure. It's comparable to tAs things get warm when you place them in a microwave. The hottest part is always the center and interior.
Under certain conditions where heat becomes extreme, part of the rock is formed under the bark. As the rock is heated, it begins to cool again and creates some of the igneous rocks that form parts of the Earth's crust. When the magma comes to the surface, especially under the ocean, where it can be much closer to the bark, it pushes the slowly cooled rock up and creates volcanic mountains, a potential source for extracting the lava.
Earth is not the only planet to which Magma exists. Recent research on Mars compared to volcanoes in Hawaii suggests the melted flow of rocks under the bark. Studies in 2007 assume that volcanoes on Mars, which were once considered extinct, can only be sleeping.
