Formation of the Earth
Timeline
- ~4.54 billion years ago: Earth formed through accretion of rock and metal from the protoplanetary disk.
- ~4.5 billion years ago: Earth was largely molten from impacts and radioactive heating; heavy metals sank to form the core, while lighter material formed the mantle and crust.
- ~4.5 billion years ago: A Mars-sized body (Theia) is thought to have collided with early Earth; debris from the impact formed the Moon.
