The Earth is four and a half billion years old, so why they started appearing then is unknown, as is the mechanism to make that continental crust.” Johnson and his colleagues are now arguing that the ...

Billions of years ago, in the giant disk of dust, gas, and rocky material that orbited our young sun, larger and larger bodies coalesced to eventually give rise to the planets, moons, and asteroids we ...

Theories around the formation of Earth have just been challenged by researchers from ETH Zurich. For a long time, the general idea saw our planet forming from a mixture of local planetesimals – the ...

Researchers at Curtin University have established a new framework for dating the Earth's evolution including the formations of continents and mineral deposits. The research, published in Earth Science ...

New research sheds light on the earliest days of the earth's formation and potentially calls into question some earlier assumptions in planetary science about the early years of rocky planets.

There are several theories about how the Earth and the Moon were formed, most involving a giant impact. They vary from a model where the impacting object strikes the newly formed Earth a glancing blow ...

Tiger Iron formed when in the sea dissolved iron reacted with free oxygen produced by the first photosynthetic life forms on Earth. For the first 2 billion years of Earth's history, there was barely ...

Here's what you'll learn when you read this story: In geological layers around the world (particularly in the southwestern U.S.) roughly one billion years of rock are missing—a mystery known as the ...

Researchers investigate the effects of oxygen content on the melting of mantle rocks and the formation of early Earth magma It is widely accepted that the early Earth largely consisted of molten magma ...

A new study shows that the so-called planetesimals that accreted together to form Earth must have been composed of dry, rocky materials. Billions of years ago, in the giant disk of dust, gas, and ...
