Nüwa created humanity due to her loneliness, which grew more intense over time. She molded yellow earth or, in other versions, yellow clay into the shape of people. These individuals later became the wealthy nobles of society, because they had been created by Nüwa's own hands.
By the Warring States Period at the end of the Zhou (3rd century BC), the Chinese explained the Earth's axial tilt, the northwestern direction of celestial bodies, and the southeastern tendency of major Chinese rivers through a legend about a great water god or monster named Gonggong who damaged Mount Buzhou after losing a battle for leadership ...
Earth formed in this manner about 4.54 billion years ago (with an uncertainty of 1%) [25] [26] [4] and was largely completed within 10–20 million years. [27] In June 2023, scientists reported evidence that the planet Earth may have formed in just three million years, much faster than the 10−100 million years thought earlier.
Additionally, the oxidation state of Earth's mantle was likely different at early times, which changes the fluxes of chemical species delivered to the atmosphere from volcanic outgassing. [9] Environmental factors from elsewhere in the solar system also affected prebiotic Earth. The Sun was ~30% dimmer overall around the time the Earth formed. [5]
Before it split into the continents we know today, Earth was home to just a single landmass, or "supercontinent," called Pangea. Over tens of millions of years, as the familiar story goes, these ...
A paleoatmosphere (or palaeoatmosphere) is an atmosphere, particularly that of Earth, at some unspecified time in the geological past.. When regarding geological history of Earth, the paleoatmosphere can be chronologically divided into the Hadean first atmosphere, which resembled the compositions of the solar nebula; the Archean second atmosphere (also known as the prebiotic atmosphere), which ...
The increase in oxygen concentrations had wide ranging and significant impacts on Earth's biosphere. Most significantly, the rise of oxygen and the oxidative depletion of greenhouse gases (especially atmospheric methane ) due to the GOE led to an icehouse Earth that caused a mass extinction of anaerobic microbes , but paved the way for the ...
Scientists long have pondered about the conditions necessary for life to arise after Earth formed about 4.5 billion years ago. The new findings fit well with the hypothesis that bodies like comets ...
