Earth’s molten youth had long-lasting consequences

A model shows that key physical properties of our planet, from the density of its iron core to its water, could have been set by interactions between a magma ocean and an early hydrogen atmosphere that was lost to space. Magma interacting with early atmosphere explains planet’s properties.
