The oldest rock formation identified on Earth is found on the shoreline of Hudson Bay in Canada. This rock formed 4.28 billion years ago. What information does a scientist need to more accurately determine the age of a rock?

1.The percentage of each mineral that makes up the rock

2.The thickness of younger rock layers that cover the rock

3.The amount of each radioactive element present in the rock

4.The amount of weathering present on the surface of the rock

Respuesta :

Scientists uses the amount of each radioactive element present in the rock to more accurately determine the age of a rock.

A scientist needs to know the amount of each radioactive element present in the rock to more accurately determine the age of a rock.

How are the age of rocks determined?

Rocks are large hard substances composed of minerals which make up the earth crust.

Rocks were formed billions of years ago.

To determine the age of rocks, the process known as radioactive dating is used where the half-lives of radioactive materials in rocks are used.

Therefore, a scientist needs to know the amount of each radioactive element present in the rock to more accurately determine the age of a rock.
