AssPSC 121 Prince Georges Community College Ice Most of earth’s fresh water is frozen PSC 121 Prince Georges Community College Ice: Two flavors # 1. Sea Ice. Ice that is floating in or covers the oceans PSC 121 Prince Georges Community College Ice: Two flavors # 2. Ice on land: glaciers Greenland, Antarctica, islands in the polar north, various mountain ranges Definitions: What are glaciers? PSC 121 Prince Georges Community College Snow that has built up and compressed into a permanent ice field. Key feature. Glaciers flow- they move. They are “icy rivers”. Two flavors of glaciers Continental glaciers: mainly Greenland and Antarctica  Pressure in center of glacier causes it to spread out Mountain/valley glaciers, also called alpine glaciers: scattered around the world  Gravity cause alpine glaciers to move down hill (like streams) Note: The continental US does not have continental glaciers! Only alpine glaciers (in the Rockies and Alaska) PSC 121 Prince Georges Community College Glaciers: how they grow and shrink: “Mass Balance” Grow in cold weather- winter snows  accumulation Shrink in warm weather (melt in summer)  ablation (note: if glacier is at edge of sea- it could calve and create icebergs) If accumulation is greater than ablation  glacier grows If ablation/calving is greater than accumulation  glacier shrinks Continental glaciers are only present in ice ages PSC 121 Prince Georges Community College We are living in an ice age because we have continental glaciers in Greenland and Antarctica. If earth has no continental glaciers- some call it a greenhouse phase But… we’re living in the warm interglacial phase. (normally we’d go back into the cold phase in 30-50 thousand years, but man made greenhouse gases will probably prevent that) What happens in ice ages? That we can discuss 1. Sea level changes 2. Erosion/deposition Why are we in an ice age now? Complicated, might have to do with arrangement of continents. To be discussed Map of earth during peak of last ice age PSC 121 Prince Georges Community College Whats different? Current (Robinson projection) PSC 121 Prince Georges Community College How much has the land area shrunk? The classic demo/experiment PSC 121 Prince Georges Community College Land mass: clay Sea ice in water Glaciers on land Add water here If the ice cubes melt- which will affect water level more? Left or right. Like wise if you take water and freeze it on land (clay) what will happen to the water level Continental Shelves and sea level PSC 121 Prince Georges Community College A small change in water level can expose or cover lots of land Continental Glaciers and sea level PSC 121 Prince Georges Community College Continental glaciers grow  sea level goes down Continental glaciers shrink (like currently)  sea level goes up Think of hydrological cycl
