A new study conducted at Florida State University and Rice University provides a new estimate of how much carbon is present in the Earth’s outer core. According to research the largest carbon source of our planet is located in Earth’s outer core.

According to research published in the journal Communications Earth & Environment, the outer core is composed of 0.3 to 2 percent carbon. Although the percentage of carbon is low, this is a huge amount because the outer core is very large. Researchers estimate that the outer core contains 5.5 to 36.8 × 10^24 grams of carbon; it’s so high number.

‘The core needs to be light elemendollarser which will reduce the density from the iron’

Study co-author Mainak Mookherjee said of the discovery: Understanding the composition of the earth’s core is one of the fundamental problems in the solid earth sciences. We know that the core of the planet is composed largely of iron, but The density of iron is more than the core.There needs to be lighter elemendollarser in the core, which reduces its density. One of these elemendollarser may be carbon. We make better estimates of how much carbon may be in the core.

Past research has also given an estimate of the total amount of carbon on the planet. But this research provides an accurate estimate of the Earth’s carbon content, ranging from about 990 parts per million to 6,400 parts per million. This is how Earth’s core, which includes both the outer core and the inner core, is the amount of carbon on the planet. can contain 93 to 95 percent

It stands for .

Sound waves used to estimate the amount of carbon

Since access to the Earth’s core is not possible, indirect methods have to be used to analyze the core. The research team simulated the known speed of compression sound waves traveling around the Earth, simulating different compositions of iron, carbon and other light elements under pressure and temperature conditions of the Earth’s outer core. compared with computer models.

Lead author Suraj Bajgain commented on the findings. When the speed of the sound waves in our simulations matches the observed speed of the sound waves traveling around the Earth, the simulations we figured out that it matched the actual chemical composition of the outer core.” he said.

Other elemendollarser was taken into account in estimating the amount of carbon

Scientists have previously tried to find a range of values ​​for the amount of carbon in the outer core. The peculiarity of this research is that other models such as oxygen, sulfur, silicon, hydrogen and nitrogen are added to models that predict the composition of the outer core. include light elementollar series narrowing this possible range.

Mookherjee,” It is quite natural to ask where this carbon that makes us who we are, comes from and how much carbon was involved in the process when the Earth was formed.” he said. Where is most of this carbon now?? How is it stored and how is it transferred between different sources? This research has given us an insight into the total amount of carbon.
