What is the age of the Earth determined to be through scientific investigation of evidence?

I recommend watching the Birth of the Earth for fun facts like this!

Select one:

a. 3.5 million years

b. 4.6 million years

c. 3.5 billion years

d. 4.6 billion years

e. 13.5 billion years

Option (D)

Explanation:

The age of the earth is approximately 4.6 billion years, where the core accretion process started to develop. This age of the earth has been determined by dating a meteorite which is one of the oldest known terrestrial rock (sample).

An approximate age of about 4.4 billion years has also been calculated by dating the smallest and oldest zircon crystals of Western Australia. The major events that have taken place in this time frame are described in terms of a scale, which is known as the Geological Time Scale.

So, according to the evidence collected by scientists, the age of the earth is estimated to be about 4.6 billion years.

Hence, the correct answer is option (D).
