Final answer:
The rich orebodies near Sudbury formed as the result of a meteorite impact that occurred approximately 1.85 billion years ago.
Step-by-step explanation:
The rich orebodies near Sudbury were formed by a meteorite impact that melted the crust and concentrated metals, leading to the creation of ore deposits. The subsequent geological processes caused the local melting of the Earth’s crust and allowed for the concentration of metals, leading to the formation of the Sudbury Basin which hosts rich deposits of nickel, copper, and other metals. The impact, melting, and differentiation of materials created a unique geologic structure that is rich in ore deposits.
