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.
The correct answer is - from solar nebula.
The Earth and the other planets in the Solar System are thought to have formed from solar nebula. This solar nebula is believed to have been a left over from the Sun's formation, being consisted of gas and dust in a disc-shape. The material in this disc-shaped gas and dust started to merge gradually, thus little by little forming bigger and bigger objects, and as the objects were getting bigger they had bigger gravitational pull so more and more material was attracted toward them. Because of the very big gravitational pull of the Sun these objects were not able to wander into the space but were instead kept close to the Sun. Because of the orbiting around the Sun, they all started to take a rounded shape. Some planets as the Earth, Venus, Mars, and Mercury became terrestrial planets, while the likes of Jupiter, Saturn, Uranus, and Neptune became gas giants.
