Approximately how old is the Earth?
4.6 billion years old
3.8 billion years old
4.6 million years old
3.8 million years old
4.6 billion years
Giga-annum It is commonly used in scientific disciplines such as cosmology and geology to signify extremely long time periods in the past. For example, the formation of the Earth occurred approximately 4.57 Ga (4.57 billion years) ago. One thousand million is also known as a billion.
If we use the American billion, it is 700 million years. If we use the British billion, it is 700,000 million years.
A thousand million years equals 1 billion years.
Earth is about 4.5 to 4.6 billion years old. The universe is about 13.7 billion years old.
A decade equals 10 years, so to convert 4 billion years to decades, simply divide by 10.4,000,000,000 years / (10 years/ decade) = 400,000,000 decades.So 4 billion years is 400 million decades
The Sun is about 4,570,000,000 years (4.57 Billion) The Earth formed shortly after, so they are almost the same age. The Sun is approximately 30 Million years older than the Earth
The current best estimate for the age of the Earth is approximately 4.6 billion years, so it is much older than 50 million years!
The Earth is currently 4.5 billion years, so in approximately 2.5 billion years time.
In science class I learned that earth is approximately 4.6 billion years old.
Well the universe wa created 4.6 billion years ago but it took a few million years to get a proper world out of it but if you want the date when it was created it was approximately 4.6 billion years ago.
== == The age of the Earth is roughly 4.6 billion years.
