That's higher than ten two-storey houses piled on top of each other. ![]() If all of the Earth's glaciers were to melt, sea levels would rise by an estimated seventy metres. If this continues, scientists predict it will have a devastating impact on the planet. Even in the Antarctic, the coldest place on Earth, there is increasing evidence that rising temperatures are causing glaciers to melt. Today, glaciers store about three quarters of the Earth's fresh water, more than all the rivers and lakes put together.Ĭlimate change is having a real impact on them. Thousands of years ago, glaciers were a feature of the landscape here in Britain and they left behind many U-shaped valleys that can be found in places like the Lake District in England and the Highlands of Scotland. Some glaciers flow all the way to the sea and when they get there, pieces of the glacier can break off and form icebergs. Artifacts These mark the surface of the culture in every organization. Schein’s Levels in an Organization Culture 1. ![]() These rocks grind together, creating tiny grains of dust, called rock flour. Schein believed that there are three levels in an organization’s culture. It all depends on how big the glacier is and how fast it is moving.Īs glacial ice moves very slowly downhill, pieces of rock and gravel get stuck between the ice and the land, forming a coarse surface, similar to the sand on sandpaper. Glaciers are made of densely packed snow that's fallen in the same place over years and years.Įach fresh fall of snow adds to the weight, crushing the layers of snow below, turning it into ice.Ī glacier is a bit like a very, very slow moving river and just like a river, it changes the landscape around it over time - a very, very long time.Īs they move along, glaciers can pick up pretty much anything in their path, from pebbles to massive boulders. Glaciation refers to the formation of huge bodies of ice called glaciers, and the way they erode and change the landscape as they move.
