Rocks from 700 million years ago hold the clues. From glaciers bulldozing landscapes to meltwater rivers flushing chemical elements into the oceans = it’s a story of how land, sea, and sky are all geochemically connected. theconversation.com/giant-glacie...

Giant glaciers pulverised Earth’s ancient rocks, setting the stage for complex life
Hundreds of millions of years ago, rocks crushed under kilometres of ice injected vital nutrients into Earth’s oceans.
