Recent research shows that Earth-like terrestrial planets are formed from a layer of dust and asteroids twisted together.
The heat vapor melts the asteroid’s ice before the water combined with the meteorite’s constituent materials mix and are twisted into the solid rock.
Scientific publications by scientists from Australia’s Curtin University and the Institute of Planetary Sciences in Arizona, USA, can change our perception of the Earth’s formation 4.5 years ago. billion years. The study is published in the journal Science Advances.
Bryan Travis, an expert at the Institute of Planetary Sciences, said: “First, the ice on meteorites will melt because of the heat released from the decay of nearby radioactive isotopes. The amount of water that forms combines. with fine dust particles to form mud.” In other words, the former Earth had a structure like a growing mud .
The team has examined the hypothesis that the rocks that made up the Earth in primitive times have more or less similarities with meteorites that have collided with the mother earth’s surface in recent years.

The meteorites and dust clumps twisted together at the center thanks to the weight of gravity have created the spherical shape of the Earth. The team also identified carbon-containing “chondrites” – meteorites older than Earth, as one of the main factors and the type of meteorites that help create today’s mother earth.
By studying these ancient meteorites, we can also detect a number of other compounds involved in the formation process.
“The unusual chemical compositions of chondrite CI and CM, the abundance of water, and the complex organic mixture found in a meteorite have led many to identify objects,” the researchers wrote in the thesis. This 4.6 billion-year-old is a precursor to terrestrial planets.”
The researchers used a “mathematical model of global meteorology and Mars” to make predictions based on this hypothesis.
The team simulated the flow of water and minerals in ancient asteroids at different size conditions. The results showed that the chemical composition of the asteroids was changed by water.
The ancient Earth may have consisted of dust and “chondrules” – small meteorite rocks that melted and condensed once again. The minerals of the rock were squeezed into the core and fine soil particles re-emerged to the surface, the team said.
