The periodic table is a chart that shows how elements are related to one another. Indium is a transition metal that is also part of the platinum family. The metals in the platinum family are also known as the noble metals. They have this name because they do not react well with other elements and compounds. They appear to be too superior to react with most other substances. In fact, iridium is the most corrosion-resistant metal known.
Precipitation falls as snow when the air temperature is below 2 Â°C. It is a myth that it needs to be below zero to snow. In fact, in this country, the heaviest snow falls tend to occur when the air temperature is between zero and 2 Â°C.
The altitude affects the temperature in the atmosphere and therefore the form of the water droplets that form the clouds. Another influence on the type of precipitation that forms is whether there are strong upward drafts of air inside the cloud. Rain is a water droplet in liquid form, usually in lower altitude clouds.Snow falls when clouds are in higher and colder altitudes, which causes the water vapor to freeze as it condenses to form ice crystals instead of water droplets that form the cloud.Sleet is rain that freezes as it is falling in cold temperatures.hese are high-altitude clouds made the same way that all clouds form, but the water droplets are frozen to form millions of tiny ice crystals. They are often the first clouds to appear in a clear, blue sky. Stratus means a flat layer or 'stretched out' in Latin.
