The first eon in Earth's history, the Hadean, begins with the Earth's formation and is followed by the Archean eon at 3.8 Ga. [2]: 145 The oldest rocks found on Earth date to about 4.0 Ga, and the oldest detrital zircon crystals in rocks to about 4.4 Ga, [34] [35] [36] soon after the formation of the Earth's crust and the Earth itself.
Earth formed about 4.54 billion years ago by accretion from the solar nebula, a disk-shaped mass of dust and gas left over from the formation of the Sun, which also created the rest of the Solar System. Initially, Earth was molten due to extreme volcanism and frequent collisions with other bodies.
Back home in North Florida, the NASA flight program of the ‘60s also inspired my older brothers. Only not in a poetic way like Ander’s image of our world. Excuse me while I travel from the ...
Depending on the rate of cooling of Earth's core, it is possible that during the Proterozoic, the magnetic field did not approximate a simple dipolar distribution, with north and south magnetic poles roughly aligning with the planet's axis as they do today. Instead, a hotter core may have circulated more vigorously and given rise to 4, 8 or ...
A map of Earth's plate tectonics. This episode explores the palaeogeography of Earth over millions of years, and its impact on the development of life on the planet. Tyson starts by explaining that the lignin-rich trees evolved in the Carboniferous period about 300 million years ago, were not edible by species at the time and would instead fall over and become carbon-rich coal.

Topics include the formation of the Solar System, the Earth, and the Moon; the formation of impact craters and how study of the Moon's surface helps us understand the early history of the Earth; the surface of Venus as it appears beneath the planet's acid rain clouds and what it tells us about the early Earth before the beginning of plate ...
