Rainwater connects the biogeochemical cycles of land and the atmosphere. It's effectively a chemical conveyor belt that delivers compounds to the ground during a process called wet deposition.

Arctic sea ice moves and spreads in ways that wind alone cannot explain. A new UC Riverside-led study finds that collisions between individual pieces of ice provide a surprisingly simple explanation for these movements, potentially offering scientists a better way to predict where sea ice will travel as the Arctic warms.
