Question

The oldest rocks found on Earth are 3.96 billion years old. However, scientists believe the Earth is about 4.6 billion years old. What evidence supports this idea? Choose all that apply.

There is no evidence to support the idea that the Earth is over 3.96 billion years old.


The moon and all the meteorites found on Earth are thought to have formed before the Earth.


The moon and all the meteorites found on Earth are about 4.6 billion years old.


All parts of the solar system are thought to have formed at the same time.

Answer 1

The moon and all the meteorites found on Earth are about 4.6 billion years old.

All parts of the solar system are thought to have formed at the same time.

Step-by-step explanation:

The oldest Earth rock is a shard of zircon found in Australia that is 4.374 billion years old.

Rock samples returned from the Moon have ages between 4.4 billion and 4.5 billion years.

The oldest meteorites we have found are 4.568 billion year old, suggesting that the solar system is about the same age.

A is wrong. There is much evidence to support the idea that the Earth is over 3.96 billion years old.

B is wrong. The Moon and all the meteorites found on Earth are only about 200 million years older than the oldest Earth rock.
