Question

Why doesn’t radiometric dating of basalt on the ocean floor provide us with an absolute age for the planet earth?

Answer 1

Answer:

Radiometric dating of basalt on the ocean floor provide us with an absolute age for the planet earth because the oceanic crust is recycled too frequently at subduction zones,

Explanation:

Radiometric dating of basalt  on the ocean floor can not provide us the absolute age of the planet earth due to the subduction. In the process of subduction oceanic plate went below the continental plate as it is less denser. It then melts there and its recycling takes place frequently. So the radiometric dating of basalt on oceanic plate can not provide us the true information regarding the age of the earth.
