WebIce sheets and glaciers reflect sunlight, and the thermal conductivity of ice and permafrost profoundly influences temperature. The cryosphere also helps regulate thermohaline circulation. This “ocean conveyor belt” has an enormous influence on marine ecosystems and biodiversity. Topography WebFrost wedging occurs in places that have the right temperatures to freeze water and then melt water. This commonly happens in polar regions and mid latitude mountains where sunlight can melt water during the day and refreeze overnight when temperatures drop.
