Snow,,,


Apa yang kalian tahu tentang salju, kawan? Untuk menambah pengetahuan sobat silakan baca artikel di bawah!

Tulisan di bawah ini naskah aslinya berbahasa Indonesia dari salah satu web pendidikan. Tenang, sumbernya saya tulis kok di bawah sana. Tapi, bakal ada yang berbeda, nih, karena di postingan kali ini bahasanya saya translet ke bahasa Inggris untuk memenuhi salah satu tugas mata pelajaran Bahasa Inggris di kelas saya. Tapi, kalau ada yang salah harap maklum ya karena saya masih belajar!

Okedeh, cekidot aja langsung! ;)

What is the snow?

Snow is water that falls from clouds that havefrozen into a solid and like rain or a crystallizedform of water ice that forms from a variety of snowflake. In the simply put, snowflake is formedfrom 2-200 snow crystal shards. These snow crystalswill form when iceattached to the powder sand or soil are scattered in the air. These crystals will then merge to form snowflakes. Snowflake shape thatthere were different kinds, depending on the temperature of the surrounding air whenformed.


How snow is formed?

Water vapor Gather in the atmosphere, collection of water vapor coolsto the condensation point, then coagulateand form clouds. Clumps of water vapor floating in the air becauseits mass is much lighter than the air underneath. After a column of steam and its massgrowing heavier, the air beneath it could no longerhold it and the clumps were also falling. If the air temperature is cold enough, clumps will fall as ice crystals (snow). Usually the air temperature is below zero degrees Celsius. But, snow can not made just by a low temperatur. When the particles of pure water is in contactwith air, pure wateris then contaminatedby other particles. There are certain particles that serve to accelerate the freezing phase, so that pure waterquickly into ice crystals. Pollutant particlesinvolved in this process is called nukleator. In addition to working to speed up the freezing phase, nukleator also serves as the glue between the watervapor. Particles of water (which is not pure anymore) joined withother water particles to form larger crystals. If the air temperaturenot to melt theice crystals, ice crystals will fall to the groundinto the snow. If the air temperature to melt the crystallinewater, the ice crystalsto the ground in the form of regular rain.

Snow structure 

Mystery about the shape of snowflakes is still a puzzle for scientists. Until now, no one knows how to create each of the snow crystals that have formed in perfectly with the six sides or six points. Scientists are still curious about the shape of snow crystals are flat or flat, not rounded like hail or water points. When the process of forming snow’s crystals until now could not be known. Snow crystal has a unique shape. No snow crystals that have the same shape in the world. Snow crystals that fell to earth in large quantities has a crystal form different from each other.
Snow has the characteristics:

  1. Snow crystals formed directly from vapor to solid (frozen) in the cloud,
  2. The shape of snow crystals usually hexagons.
  3. The shape of snow crystals depends on temperature and humidity.
  4. Granules are formed from 2-200 snow snowflakes,
  5. Actually the snow is colorless. Because of the snow crystals in the form of prisms, snow refract light into all the colors the eye sees as white. The color of snow can change if contaminated dust released into the atmosphere. For example the local soil is red, snow was colored reddish or pink.

Influence of snow for human life
In some cases, snow can be used for activities such as skiing, snow shoe play, until the sled with the dogs as pullers. but if the snow fell heavily, the snow could damage the basic infrastructure such as electricity, telephone, and gas lines that are an essential part of human life.

1.            Influence in the field of agriculture

Snow that falls in agricultural areas have a good effect. Snow that falls in large quantities and buried in long periods of time can be used as a backup water supply during the spring. With sufficient water reserves in the spring so crops can be well controlled.

2.            Snow as a recreational facilities
There are so many sports that can be performed on a snowy winter such as skiing, snowboarding, snowmobiling and snowshoeing depending on the circumstances existing snow. For children with very nice snow, they use it as a means of war play like snow, playing sled, a snowman, and creating a snow palaces.
