A new study conducted at Florida State University and Rice University has provided a new estimate of how much carbon is present in the Earth’s outer core. According to the 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 measure because the outer core is very large. Researchers estimate that the outer core contains 5.5 to 36.8 × 10^24 grams of carbon; that’s a huge number.

‘There must be light elements in the core that will reduce the density from iron’

Research co-author Mainak Mookherjee said of the discovery: Understanding the composition of the earth’s core is one of the fundamental issues in the solid earth sciences. We know that the core of the planet is mostly iron, but The density of iron is more than the core.There are supposed to be lighter elements in the core that reduce its density. One of these elements could be carbon. We’re making better claims about how much carbon there might be in the core.

Past research has also claimed a measure of the total carbon on the planet. But this research offers an accurate estimate of the Earth’s carbon content, from about 990 modules per million to a value in the middle of 6,400 modules. This is the measure of carbon on the planet, the core of the Earth, which includes both the outer core and the inner core. can contain 93 to 95 percent

It means .

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

Chief 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 elements were also taken into account in the carbon measure claim

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

Mookherjee,” It is quite natural to ask where this carbon that makes us us came 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 transferred in the middle of different sources? This research has given us an insight into the measure of total carbon.
