Deskripsi proses tejadinya hujan es dalam bahasa Inggris (minimal 20 kalimat)
GrayenStarting from gathering moisture in the atmosphere of the Earth, a collection of water vapor cools to the point of condensation (ie the temperature at which a gas turns into a liquid or solid form), then coagulate to form clouds. At the beginning of the formation of clouds, its mass is much smaller than the mass of air so that the clouds float in the air just like the wooden beams that float on the water surface. However, after the vapor collection continues to grow and merge into the clouds, its mass also increases, so that at some point the air can no longer hold it. The clouds broke and the water particles fell to Earth.
Particles falling water that is pure water (not contaminated by other particles). Pure water does not immediately freeze at 0 degrees Celsius, because at this temperature the phase change from liquid to solid. To make the required freezing temperature of pure water is lower than 0 degrees Celsius. This also happens when we boil water, the water evaporates when the temperature is above 100 degrees Celsius to 100 degrees Celsius because it is a phase change from liquid to vapor. To speed up the phase change of a substance, usually added to a particular substance, such as salt used to accelerate the melting of the ice into the water phase.
Usually the air temperature just below the clouds is below 0 degrees Celsius (depending on the air temperature at the height above sea level). However, low temperature alone is not enough to create snow. When particles of pure water is in contact with air, the pure water is contaminated by other particles. There are certain particles that function accelerates the freezing phase, so that pure water quickly become ice crystals.
Impurity particles involved in this process is called nukleator, in addition to functioning as a promoter freezing phase, also adhesive antaruap water. So the water particles (which are not pure anymore) joined together with other water particles to form larger crystals.
If the air temperature is not to melt the ice crystals, ice crystals fall to the ground. And this snow! Otherwise, the ice crystals melt and get to the ground in the form of rain water.
In many cases in the world, the rain always starts with snow while he was falling from the clouds, but then melt when crossing the hot air. Sometimes, if the temperature is very low, the ice crystals can form small balls of ice and there was hail. Bandung include the relatively frequent hail. So, this is why the snow is very hard to come down naturally in tropical regions that have relatively high air temperatures than areas that are experiencing winter.
Possesses a unique structure, no snow crystals that have the same form in this world as our fingerprints. Imagine, snow has fallen since the earth is created until now, and none of the snow which has the same crystal structure form!
The uniqueness of the other is snow white color. If it is snowing heavily, the expanse of the earth be white, clean, and seemed to glow. This is due to the structure of snow crystals allows the snow to reflect all colors in all directions in the same amount, then comes the white color. The same phenomenon can also be seen when we find white sand, chunks of salt, sugar lumps, fog, clouds, and white paint.
In addition, snowfall giving warmth. This can be understood from the concept of effective temperature. Effective temperature is the temperature felt by the skin, is influenced by three physical quantities: the measured temperature (thermometer), the speed of air movement, and humidity. Effective temperature is usually used to determine the "comfort zone". On the beach, the measured temperature can be high, but due to high winds we still feel comfortable. At the time of heavy snow, the humidity rises and this affects the effective temperature so that in one condition we feel warm.
