How do scientists find the ages of rocks? (1 point)

They measure the amount of the decay of particular unstable atoms in a rock.

There is no completely accurate way to date rocks.

They measure rocks as they age; the bigger the rock of a particular type, the older they are.

All rocks on Earth will be about the age of Earth because rocks cannot be truly destroyed once created.
