Contoh Explanation Text About Snow Terbaru – Apakah kalian pernah melihat salju? Memang di Indonesia tidak akan pernah turun salju, kecuali di puncak gunung Jaya Wijaya. Akan tetapi, apakah kalian mengetahui bagaimana salju dapat terbentuk? Berikut adalah contoh Explanation Text yang menjelaskan terbentuknya salju.
Process of Snow Showers
Snow is water that falls from clouds that has been frozen into a solid and is like rain or a crystallized form of water ice that is formed from a variety of snowflakes. The snow crystals are formed when ice stuck in sand or ground powder scattered in the air. These crystals will then join and form snowflakes. The shapes of snowflakes have different kinds, depending on the temperature of the surrounding air when it is formed.
The Stages of Snow:
Water vapor gather in the atmosphere, a collection of water vapor cools to the point of condensation and agglomerate to form clouds. The clumps of water vapor is floating in the air because of its mass is much lighter than air underneath. After a column of steam continues to grow and builds the heavier mass, the air underneath can no longer hold it and it crashes.
The air temperature is quite cold underneath before falling in the form of lumps of ice crystals (snow). Usually the air temperature below the cloud is below zero degrees Celsius. However, low temperature alone is not enough to create snow. When particles of pure water is in contact with air, pure water is contaminated by other particles. There are certain particles that function accelerates the freezing phase, so that the pure water quickly become ice crystals.
Pollutant particles that are involved in this process are called nukleators. In addition serves to accelerate the freezing phase, nukleator also serves as an adhesive between water vapor. Particles of water (which is not pure anymore) joins with other water particles to form larger crystals. If the air temperature does not melt the ice crystals, ice crystals will fall to the ground into the snow. If the air temperature melt the crystal water, the ice crystals fall to the ground in the form of normal rain water.[sc:ads]
The white color of snow is very interesting to observe. The concentration of electricity in ice crystals is higher than water or air. Therefore snowflake shapes like a prism that reflects all colors in all directions in the same amount, then comes the white color. In the world, the land of snow is common in places with subtropical and cold climates. However, there are also tropical snowy, namely in the Jayawijaya Mountains in Papua, Indonesia.
The mystery of snowflakes is still a puzzle for scientists. Until now, no one knows how to create each of the snow crystals that have formed perfectly with 6 sides or 6 points. Scientists are still curious about the shape of snow crystals are flat, not round like the hail or water point. The processing time of snow crystal formation until now could not be known. Snow crystal has a unique shape. There is no snow crystals that has the same form in the world. Crystal snow falls down to earth in large quantities which has a crystal form different from one another.
The characteristics of snow are first, snow crystals are formed from steam directly into a solid (frozen) in the clouds. Second, the shape of snow crystals are usually hexagon. Next, the shape of snow crystals depends on the temperature and humidity. Next, snow is actually colorless. Because it consists of snow crystals that form a prism, snow refract light into all the colors that the eye sees as white. Color snow could change if contaminated with dust that fly into the atmosphere.
Snow for most people is a beautiful natural phenomenon but sometimes snow can be a terrible thing for snow may cause a storm called a blizzard. Snowstorms are storms where large amounts of snow fall. Snow makes its density smaller than water in a liquid state (liquid), by a factor of about 10 at temperatures slightly below freezing, and even more in cooler temperatures. Therefore the amount of water will produce 0.8-inch (2 cm) of rain could produce at least 8 in (20 cm) of snow. Two inches of snow (5 cm) is enough to make a serious disruption to transport traffic and schools (because of the difficulty to push and maneuver a school bus on a slippery road). This is especially true in places where snow is rare, but can accumulate heavy snowfalls occur (eg, Dallas, Atlanta, Seattle, London, Dublin, Canberra, Vancouver and Las Vegas).
