Glacier and glaciatio chapter 12

CHAPTER 12 – GLACIERS AND GLACIATION Today glaciers cover nearly 10 percent of Earth’s land surface; however, in the recent geologic past ice sheets were three times more extensive, covering vast areas with ice thousands of meters thick. Many regions still bear the mark of these glaciers. The basic character of such diverse places as the Alps, Cape Cod, and Yosemite Valley was fashioned by now-vanished masses of glacial ice. Moreover, Long Island, the Great Lakes, and the fiords of Norway and Alaska all owe their existence to glaciers. Glaciers, o course, are not just a phenomenon of the geologic past. As you will see, they are still sculpting and depositing debris in many regions today. GLACIERS: A PART OF TWO BASIC CYCLES Glaciers are a part of two fundamental cycles in the Earth system, the hydrologic cycle and the rock cycle. Earlier you learned that the water of the hydrosphere is constantly cycled through the atmosphere, biosphere, and solid Earth. Time and time again, the same water evaporates from the ocean into the atmosphere, precipitates upon the land, and flows in rivers and underground back to the sea. However, when precipitation falls at high elevations or high latitudes, the water may not immediately make its way toward the sea. Instead, it may become part of a glacier. Although the ice will eventually melt, allowing the water to continue is path to the sea, water can be stored as glacial ice for many tens, hundreds, or even thousands of years.…

largest. This is due to the high thermal insulation provided by the vacuum gaps either side of the middle glass pane; consequently the heat absorbed from the sun by the middle glass pane cannot be easily transferred to the indoor and outdoor environments. For 0.5 m by 0.5 m and 1 m by 1 m triple vacuum glazing exposed, to isolation levels greater than 200 W.m-2 and 180 W.m-2 respectively with four 0.03 emittance coatings, the middle glass sheet temperature is larger than that of the…

These measures are based on a hypothetical Single Policy Company model. Accounting rules are applied to project the Income and Equity of the company and the flows of money between the company and its equity investors. These are called Equity Flows. The three measures are: i)…

não somente registre, mas também controle as variáveis do processo (temperatura, vazão, pressão...). É necessário controlar os desvios e corrigi-los rapidamente. Controle informatizado do processo. Custos são altos para pequenas produções mas se diluem para grandes produções. PROCESSO CONTÍNUO E PROCESSO DESCONTÍNUO O processo descontínuo é utilizado quando o volume de produção é pequeno, quando o custo de produção é mais favorável que o do processo contínuo ou quando…
