land ice Flashcards
ice cap
ice mass that covers less than 50,000km2 of land area.
ice sheet
ice mass that covers more than 50,000 km2 of land area.
glaciers
ice masses originating on land, undergoing movement to transport ice from area of accumulation to area of ablation.
a river of ice that flows under its own weight due to gravity
alpine glaciers
land terminating glaciers in mountainous areas. influenced by atm temp and precipitation
tidewater glaciers
marine terminating glaciers. Influenced by atm & oceanic temp and precip
ice shelf
glaciers that have gone afloat. Too thin to touch the seafloor. Loss of ice shelves does not directly affect sea level but they are tightly coupled to inland ice. Ice shelf mass balance matters to sea level
ice stream
carry ice from the interior of the continent to the outlet glaciers and ice shelves
