Scientists have uncovered evidence that a significant portion of the Earth's crust was eroded during 'Snowball Earth.'

This erosion event, called 'The Great Unconformity,' stripped away an average of 3-5 kilometers of rock.

The erosion left a gap in the geological record of approximately one billion cubic kilometers.

The eroded material was likely washed out to sea by glaciers.

This phenomenon explains the absence of older asteroid craters and the presence of younger ones.

Isotopic analysis of crystals indicates the erosion occurred before the Phanerozoic era.

The findings shed light on missing geological history.
