Since physical and chemical erosion yield comparable carbon fluxes, studying both together is essential to avoid biases in erosion-driven carbon flux estimates.
The 700–1,300 feet-wide space rock deformed rocks more than six miles from the impact site when it hit 600 million years ago.
Kanan and Chen were inspired by cement production, where a kiln, or furnace, converts limestone (a sedimentary rock) into a reactive chemical compound called calcium oxide, which is then mixed ...
