The phenomenon of ice on earthBy eXplorer. Filed in Other |
Ice can be found in all corners of the earth. Usually, there are in the mountains that very high, or in the pole of the earth, be it the north pole or north pole. Chemical law of ice formation is very simple. The main components of the formation of ice is water. The nature of water, when heated 100 degrees Celsius will boil. Meanwhile, if the water in the chill to zero degrees Celsius will freeze and become ice.
Ice has a transparent color, like water. Form of ice that is found can vary, for example, there are shaped chunks. There is also ice that is soft and can be eaten, like ice cream. Likewise, the snow, which is a grain of ice floating in the air.
Snow is formed because the mass of water vapor in the clouds, much smaller than the air. So that the clouds are floating in the air. After the collection of water vapor continues to grow and merge into the cloud, the mass of water vapor to be increasing rapidly, so that air is not strong anymore to hold it. Clouds are breaking, and the particles fall to earth.
The particles are pure water, which froze at zero degrees Celsius temperature or even minus 40 degrees Celsius in the air. As a result, liquid particles are turned into solids and contaminated by other particles in the air, then there was snow. For snow weighing about 1.5 kilograms, only produce 750 milliliters of water or no more than one liter of water.
When winter arrives, temperatures of minus zero degrees Celsius can freeze the puddle of water in a large area, such as rivers or lakes. Therefore, in winter, the lake surface can be used as ice-skating arena.
The world’s largest ice shelf on the south pole, in Antarctica. Almost 70 percent of the water on earth, are in place. If Antarctica melted, then the entire ocean surface of the earth will rise as high as 266 feet. As for the mainland of the world’s second largest ice is located in Greenland. If Greenland is melting, the sea level will rise about 25 feet. Antarctic sea ice is the thickest in the earth. Its thickness is estimated as deep as 4770 meters. Plain ice is also thought to be the world’s oldest continent. The process of formation is about 750 years ago.
In Greenland there are 600 thousand cubic miles of ice. Temperatures in the area are ranging between minus 24-45 degrees Celsius, although it had a record to minus 89.3 degrees Celsius. There are also glaciers Columbia, in Alaska, which supports the third largest ice or land. In the past, Columbia has a very thick layer of ice, but in the last 20 years has experienced an erosion area of nine miles.
The world’s largest glaciers avalanches have occurred in Kutiah, glaciers are located in Pakistan, in 1953. When the liquid ice was moving at 12 kilometers per hour, for three months non stop. With volume at 112 cubic meters per day.
There is also shaped monopolit glaciers, which formed about 108 million years ago, which is now named as Yosemite National Park’s El Capitan. Here there are canyons of ice covering an area of 3000 feet. The edges to form the walls of cliffs, which can climb. Each year, the canyon is also the more experienced erosion and melting. Even as more high temperatures on the earth due to air pollution, creating icebergs like the Himalayas and the Andes are also experiencing erosion.

It is actually difficult to find well-informed individuals about this issue, but you seem like you are aware of what you are writing about! Appreciate it
