Over the winter break‚ me and my classmate decided to go to one of the national park‚ that place is Glacier Bay National Park and Preserve in Alaska. We also invited our school teachers. We chose to go with ferry but I am the only one who chose to go with my own car because I always arrive late so I thought it was a good choice for me. But one of my teacher worried that I might not know the way to the park so she follow me. I also take my pet bird Kiwi and my precious teddy bear with me. It was a

The rest of water is in the form of glaciers and ice caps (2.1%)‚ ground water (0.6%)‚ inland water (0.2%) and water vapours (0.001%). Water is neutral to litmus. Its freezing point is 00C and melting point is 1000C. It is also regarded as “Universal solvent”. The importance of water is undeniable. Fish is the queen of water‚ whose life is water; It is scared of

The evidence of these glacial and interglacial cycles was found in deep sea sediments. These large glaciers molded the land creating lakes and rivers in its path. The temperatures varied greatly between the glacial and interglacial periods. As research shows temperatures affect the wind and ocean currents. This in turn affects the amount of precipitation and dryness around the world. When the glaciers present a land bridge called the Bering Strait (Figure 1.4) between Alaska and Siberia revealed itself

Pre A level task Geography Erosional landforms: Corrie = Corries‚ also known as cirques‚ are often the starting point of a glacier. Snowflakes collect in a hollow. As more snow falls‚ the snow is compressed and the air is squeezed out to become firm. With the pressure of more layers of snow‚ the firm will‚ over thousands of years‚ become glacier ice. Erosion and weathering by abrasion‚ plucking and freeze-thaw action will gradually make the hollow bigger. Corries will decrease because of

assistance of glaciers‚ hence the name glaciated valley‚ this would have been classified it as being formed through a chemical weathering process. A U valley always starts as a typical V shaped valley however through the shape of the glacier‚ it uniformly turns the landscape into a U shape. A Glaciated Valley forms when a glacier travels down a slope. A glacier is a slow moving mass of ice that is formed by the accumulated and compacted snow on the mountains. When this glacier travels down the

Reading Assignment: Chronicles of Ice Summary: In Chronicles of Ice‚ Gretel Ehrlich sets out to “learn whatever lessons a glacier has to teach”‚ and to share what she has learned with us‚ as readers. The lesson the author relays to us is that the fate of the glacier is inextricably linked to that of the biological health of the Earth itself. Ehrlich uses the glacier as a device to show both cause and effect of the declining health of the Earth’s climate. The gases and particulate trapped in the ice
