How old are living things?
Simple life forms like bacteria have on the Earth for about 3,500,000,000 years ago (3.5 billion years). Evidence of this was found in very old rocks in Australia. The estimated age of the earth is 4.5 billion years so life originated just 1 billion years after the earth formed.
How many years ago was the first plant on earth?
The first cells emerged about 3 billion years ago, and about 1 billion years later, the first plant-like things came about, though they didn't really resemble current day plants. They were exclusively underwater and weren't as adapt to their environment as they are today.
How long will a star like earth's sun last?
13 billion years, roughly. Our sun was created about 6.5 billion years ago so it is just starting middle-age.
What is percanbrian?
If you mean precambrian? It is an epoc in the earth's history. Something like 4 billion years ago.
What was life like at the beginning of earthHow is that different from life now?
When the Earth was formed, there was no life for a billion years.
Can we move the moon closer to earth like it was billion of years ago?
No, I don't think that's possible to happen.
How was the earth like 4.0 billion years?
HOT!!! 4 billion years ago, the Earth was still newly re-formed and becoming solid, after the titanic collision with another planet perhaps as large as Mars.There probably wasn't much in the way of atmosphere or surface water. No life at all; that would come a little less than a billion years later.
When did life on earth begin to evolve?
Scientific evidence suggests that life began on Earth approximately 3.5 billion years ago. The Earth formed 4.5 billion Years ago. The Earth was a dead planet for about 1 billion years. Some evidence would suggest that the first forms of life began more like 3.8 billion years ago, in which case the Earth was dead only 700 million years. The study of the processes which resulted in the beginning of life is called Abiogenesis. If it worked the same on other planets on other Sun in other galaxies, life may have begin 10 billion years ago in other galaxies. See related links. Note also that there are dozens of explanations for the beginning on life on Earth, including many based on religion.
How many years have been volcanoes been around?
i like cheese when it is fried in a frying pan or boiled in a soup
How long have the carbon atoms in your body been on the earth?
Approximately 3.5 billion years; carbon, like all elements, is frangible.
What is the life span of the planet earth?
Planet Earth has existed about as long as the Solar System - something like 4.6 billion years. For the future, it is harder to know how long it will last. In a few hundred million years, it is expected to get too hot for life to exist on planet Earth, but the planet will continue existing. In 4 or 5 billion years, Earth will ultimately be swallowed up by the expanding Sun.
What does the geologic timescale encompass tens of millions or hundreds of millions of years?
More like over 4 billion years - that's the approximate age of planet Earth.
