In English-speaking countries, "trillion" usually means a million million (1012). In some other countries, it may mean a million million million (1018). Even with the first definition (the "short scale", a trillion years is much more than the age of the Universe.
The Earth formed about 4.6 billion years ago, and the first life forms are believed to have appeared around 3.5 to 4 billion years ago. This means there was a period of roughly 500 million to 1 billion years between the formation of Earth and the emergence of life.
It means years x 10 to the power of 9. It is the unit that the age of of the earth is measured in. It stands for Giga Anum Giga = 10^9 and Anum = 1 year
The Earth is about 4.5 billion years old. Life appeared on Earth about 3.5 billion years ago. The Earth would have been about 1 billion years old at that time.
Most diamonds are estimated to be between 1 billion to 3.3 billion years old. These diamonds are formed deep within the Earth's mantle under high pressure and temperature conditions over billions of years.
The first supercontinent formed 1 billion years ago was called Rodinia. It is believed to have existed during the Neoproterozoic era and eventually broke apart to form the continents we have today.
We'd probably use the term 1 gigayear to mean 1 billion years (in the U.S.). The prefix "giga" means 1,000,000,000 or, if you prefer, 106 units of something. The gigayear is a billion years, just the the gigaHertz is a billion Hertz (or cycles per second). Also note that we use a "big" G to represent giga. A Gyear is a gigayear or a billion years.Many consider an Eon to be a billion years
1,000,000,000,000,000 years
it is called an eon
The prefix "giga" means 10 to the 9 or 1 billion.
1 billion years = 365.25 billion days (rounded)
The year in 1 billion years will be 1000002016
The prefix is GIGA, not "GIGO", and it means 1 billion (U.S. term) or a milliard (U.K. term) - 10**9 in either case.
1/4: Half would be gone after a billion years and half of that would be gone in another billion years. 1/4: Half would be gone after a billion years and half of that would be gone in another billion years. 1/4: Half would be gone after a billion years and half of that would be gone in another billion years.
3 hours = 3 hours PAST 12 o'clock = (3 x 1 billion) - 4.6 billion = 3 billion - 4.6 billion = -1.6 billion years = 1.6 billion years ago6 hours = 6 hours PAST 12 o'clock = -1.6 billion years + (3 x 1 billion) = -1.6 billion + 3 billion = 1.4 billion years ago
There are 12 months in a year, so there are 12 billion months in a billion years.
There are 1000 sets of 1 million years in a billion years.
10000 lakhs = 1 billion
