Contoh Explanation Text About Snow Yang Harus Anda Baca – Snow atau salju merupakan fenomena alam yang sering terjadi di berbagai belahan dunia. Anda akan menyaksikan sebuah butiran es yang berwarna putih turun dari langit, tetapi tidak di Indonesia. Salju turun di berbagai tempat terutama daerah sub-tropis dan beriklim sedang.
Salju biasa turun di negara benua Amerika dan Eropa. Sebenarnya, apa itu salju, bagaimana salju bisa terjadi, dan mengapa salju hanya turun di daerah sub tropis? Anda bisa mengetahui jawabannya setelah membaca contoh explanation text about snow berikut ini.
Snow is water droplets that fall from clouds. Then, those falling waters becomes solid. You need to know that rain consists of water vapor particles, then cooled in the air. They fell to the earth as pieces of soft, white, and shaped like crystals. When the air temperature has been hot, the snow began to melt and disappear. It turns directly into water vapor and the process is called the sublime. Meanwhile, the opposite process is called deposition. Snow falls in the country with a subtropical and a temperate climate. However, you can also find those in Indonesia. Snow in Indonesia are in Jayawijaya and Barisan Sudirman Papua, Indonesia.
To answer how the snow happens, we can start from the water vapor in Earth’s atmosphere which are assembled. A mass of water vapor cools to the point of condensation (the temperature in which a gas turns into a liquid or a solid form), then those waters coagulate to form clouds. At the beginning, the mass of cloud formation is much smaller than the mass of air so that those can float in the air. When you see, that’s just like the wooden beams floating on the water surface. However, after the steam increases and merges inside the clouds, its mass also increases, so that at some point the air can no longer hold it. The clouds then break up and the water particles fall to Earth.
The water particles that fall are the pure one. It means that the water does not contaminated by the other particles. Usually the air temperature below the cloud is below the 0 degrees Celsius (depending on the air temperature at the height above the sea level). However, only a low temperature is not enough to create the snow. When particles of pure water are in contact with air, those main parts are contaminated by the other particles. There are certain particles to accelerate the freezing phase, so that pure water quickly becomes crystals of ice.
Impurity particles involved in this process is called nukleator, in addition to function as an accelerating phase of clotting, it also becomes an adhesive among the water vapor. So that, the water particles (which are not pure anymore) joined together with other water particles to form larger crystals. If the air temperature does not melt the ice crystals, those will fall to the ground. Then, here’s the snow! If the snow is not formed, the ice melts and gets to the ground in the form of rain water.
In many cases around the world, the rain process always begins with a snow when it falls from the clouds, but then melts when it crosses the heat temperature. Sometimes, if the temperature is very low, the ice crystals can form tiny balls of ice. Bandung is one of the places that frequently gets the hail. So, this is why the snow is very hard to fall naturally in tropical regions because the places including Indonesia have high air temperatures and it makes the ice balls melt.
