Usually, the temperature can reach about 500 degrees Celsius to 1,000 degrees Celsius.However, this is true for the temperature of the earth’s crust.

Iron and magnesium richness is also found in lower gabbro layers, the layered structure is cumulate. Under the sea For the first time, scientists have discovered microbes living deep inside Earth’s oceanic crust — the dark volcanic rock at the bottom of the sea. The pushing forces the old oceanic crust on the plate margins to bump into the edges of other plates. Some examples of igneous rocks such as basalt, granite, and andesite. Basalt stone is one type of earth rock formed from magma freezing and it is an alkaline. Seawater in hydrothermal vents can reach temperatures above 700 degrees Fahrenheit. Where in this case there will be so many earthquakes, tsunamis and some of the biggest, terrible and worst volcanic eruptions happening in the world. The oceanic crust is much bigger. Unlike oceanic crust that has young geological rock, continents can have rocks up to 4 billion years old. These igneous rocks are formed by the cooling process and liquid magma crystallization in volcanoes and mid-ocean mountains. In this process, one plate moves below the other and sinks due to gravity into the mantle. The newborn rock — mostly basalt — is pushed away from the ridges and becomes buried under thick sediment. The article was first published on March 14, 2013. That is along the middle seas in the subduction zone and the continental shelf. This crust is several kilometers thick and covers 60% of the planet’s surface, making it the largest habitat on Earth. If similar microbes are found throughout it, the crust “would be the first major ecosystem on Earth to run on chemical energy rather than sunlight”, says Mark Lever, an ecologist at Aarhus University in Denmark, who led the study.

In ancient Roman history, these stones were used to build roads and monuments. New crust constantly rises to the ocean surface along the mid-ocean ridge system, a giant underwater mountain range that snakes through the oceans like the stitching on a baseball. Although scientists have long known that microbes live in this sediment and in exposed basalt that has not yet been covered, the deeper, buried parts of the crust have been a mystery. The main reason is the mantle-crust made of felsic rock. The oceanic crust is younger than the continental crust of 3.8 billion years old. Microbes have been found living deep inside crust at the bottom of the sea. The transition from land to sea begins at the continental shelf, a gently sloping, submerged extension of the continent. Magma is produced by smelting the earth’s mantle and rising below the ocean’s surface. This article is reproduced with permission from the magazine Nature. When two continental plates converge, they form ____. Basalt stones are found at the bottom of the oceanic crust. Oceanic crust is thin and young -- no more than about 20 km thick and no older than about 180 million years. This layer of crust is solid and this layer is in the present of lithosphere layer.It is said by researchers that in oceanic lithosphere is denser than lithosphere in the continent. The temperature of the oceanic crust is only about 200-400 degrees Celcius. However, over time, these igneous rocks will experience weathering and erosion from exposure to water and the atmosphere. Of course, it beats the previous record of 100 years. The slope leads down to the ocean abyss and its plains, plateaus, mountains, ridges, and trenches—hidden from view except for the tops of certain features that rise above the water's surface as islands. According to geography, the age of the oceanic crust is 200 million years. And rain it did. The magma chamber is an area beneath the surface of the earth where many rock pools are collected. The melted liquids are rich in silica minerals which is produce basaltic magma. Oceanic crust is one part of the lithosphere that located in the ocean basin. “Given the large volume of sub-sea-floor crust, one can’t help but wonder how the amount of living biomass there compares to that at the Earth’s surface,” says Konhauser. These lava shaped small hills at the center of the spread. We know that hydrothermal vents are one of the wonders found on the ocean floor. It has been described in the previous point that the oceanic crust is composed of several rock types and they have a lower thickness than the earth’s crust. The results are published in Science. This area is a collision area between the oceanic and continental lithocyte plates. Where pieces of ocean crust collide, especially deep trenches form. All rights reserved. Described by several sources that the oceanic crust is composed of mafic rock or sima that are rich in iron and magnesium also silica (poor). Once deep in the mantle, the crust melts into magma only to be spewed back to the surface along a mid-ocean ridge or an isolated volcano. Lever is convinced that the microbes are not hitchhikers from the surface, but genuine residents of the crust. Oceanic crust or oceanic plate can be found in the circum-Pacific region. This process, known as chemosynthesis, is distinct from photosynthesis, which uses sunlight for the same purpose. Magma moves upward toward the surface of the earth through a path that is found. Layers of rock piled together and the vast amounts of steam that volcanoes spewed into the atmosphere turned to water vapor, condensed, and fell as rain. Oceanic crust, extending 5-10 kilometers (3-6 kilometers) beneath the ocean floor, is mostly composed of different types of basalts. Oceanic crust is born at the mid-ocean ridges, where plates are pulled apart. Hopefully, this post 17 General Characteristics of Oceanic Crust may benefit for us.
