Precambrian Time Precambrian time covers the vast bulk of the Earth's history, starting with the planet's creation about 4.5 billion years ago and ending with the emergence of complex, multicelled life-forms almost four billion years later.ome three billion years ago the Earth's atmosphere was virtually devoid of oxygen. At about 2.4 billion years ago, oxygen was released from the seas as a byproduct of photosynthesis by cyanobacteria. Levels of the gas gradually climbed, reaching about one percent around two billion years ago.

school energy&environment How long does it take to form? The time needed to form a soil depends on the latitude: in environments characterized by a mild climate, it takes 200-400 years to form 1 cm of soil; in wet tropical areas soil formation is faster, as it takes 200 years; in order to accumulate enough substances to make a soil fertile it takes 3000 years.

How long did creation take? God took billions of years to create the original earth, and to allow all of the species of life to evolve. In an operation similar to that of a editor program's cut and paste function, God copied that original earth and created a duplicate copy. The latter is the earth that we live on.

- Most physicists believe the earth is 4.5 billion years old. And the results of Terra, run with that assumption, works out OK. On the other hand, run the program assuming the earth is less than 10,000 years old, and that there was a catastrophic universal Flood, and all the geology works out OK that way also!

How did planet Earth form? Earth formed around 4.54 billion years ago by accretion from the solar nebula. Volcanic outgassing probably created the primordial atmosphere and then the ocean; but the atmosphere contained almost no oxygen and so would have been toxic to most modern life including humans.

How did planet Earth form? The age of Earth is approximately one-third of the age of the universe. An immense amount of geological change has occurred in that timespan, accompanied by biological change. Earth formed around 4.54 billion years ago by accretion from the solar nebula. Volcanic outgassing probably created the primordial atmosphere and then the ocean; but the atmosphere contained almost no oxygen and so would have been toxic to most modern life including humans.

How Long Will The Earth Be Habitable? Scientists Estimate Planet Can Support Life 1.75 Billion Years [REPORT] We estimate that Earth will cease to be habitable somewhere between 1.75 and 3.25 billion years from now, Rushby said. Once Earth enters the suns hot zone it will no longer be able to host life causing a massive extinction of all the planet's inhabitants.

How did the Earth come into existence? The widely accepted theory of how Earth was formed nearly 4.50 billion years ago is by core accretion. Earth's rocky core formed first, with heavy elements colliding and binding together. Dense material sank to the center, while the lighter material created the crust. Gravity captured some of the gases that made up the planet's early atmosphere. The planet's magnetic field probably formed around this time.

Geologic and Biological Timeline of the Earth Simplified model of. the formation of the Moon. Approximately 4,000 million years ago, the earth was cool enough for land masses to form. The supercontinent Rodinia was formed about 1100 million years ago, and it broke into several pieces that drifted apart 750 million years ago.

- He took them to the Argonne National Laboratory, where he was granted time on a late-model mass spectrometer. In a meeting in Wisconsin soon afterward, Patterson revealed the results of his study. The definitive age of the Earth is 4.550 billion years (give or take 70 million years). The current estimate for the age of the earth is 4.54 ± 0.05 billion years (4.54 × 109 years ± 1%).

Follow BBC Earth That includes life on Earth, which will surely be wiped out eventually. But how long does it have? The fossil record tells us that life on Earth has lasted at least 3.5 billion years. In that time it has survived being frozen, clobbered by rocks from space, mass poisoning, and even lethal radiation.

Ask GeoMan... ...a very long time, at least according to the way humans measure time. Based on relative and absolute age dating techniques, geologists now think that the earth was formed about 4,600,000,000 years ago. One of the challenges of any study of the earth is being able to comprehend just how long this is, and for what an extremely small part of it humans have been here.
