Silica-rich materials are responsible for the making up of 90 percent of the earth's continental crust, such as feldspar and quartz. But what is the origin of these silica-rich materials? Can it be a clue for searching life on other planets? The conventional theory known till now about the earth's crust formation is that the crustal ingredients are formed by volcanic activity.
As Phys.org cited, a new theory has been found in the formation of earth's crust. Earth scientists from McGill University have found and published a new theory, i.e. a portion of the chemical parts of this material settled onto Earth's initial surface from the hot air that was prevailed at the time. Scientists who were involved in the study are Don Baker and Kassandra Sofonio from the same university.
Initially, there was an antiquated geochemical history behind the formation of earth's crust. Scientists trust that a Mars-sized planetoid furrowed into the proto-Earth around 4.5 billion years back, dissolving the Earth and transforming it into a sea of magma. In the wake of that effect which likewise sufficiently made garbage to frame the moon-the Earth's surface slowly cooled until it was pretty much strong. Baker's new hypothesis, similar to the regular one, depends on that introduction.
Science Daily reported that for testing the new theory on the formation of the earth's crust, both scientists developed a series of laboratory experiments which was designed for giving a mimic to the steamy conditions on early earth atmosphere. They spent months for developing the required environment. The research experiments were guided by other researchers' past trials on rock-water interactions at high pressures, and by the McGill group's own preparatory counts.
The research paper on the formation of earth's crust was published in journal Earth and Planetary Science Letters. "Our experiments demonstrate the science of this procedure and could give researchers critical intimations as to which exoplanets may have the ability to harbor life," Baker says. "This time in early Earth's history is still truly energizing," he includes.
