Question

Quizplus · Accepted Answer

The majority of Earth's elements, including metals and rocks, were produced by nuclear fusion in stars. As stars undergo fusion reactions, they generate heavier elements that can eventually be dispersed into space through supernova explosions. These dispersed materials can then accrete into new celestial bodies, such as planets. This process is known as nucleosynthesis.
