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.
Imagine a drop or flake falling through a long tube that contains the air between the clouds and the Earth. The air inside the imaginary tube is the atmosphere. Differences in temperatures in different parts of the atmosphere account for the differences we see between snow, sleet, and freezing rain. The liquid precipitation that falls to Earth's surface is rain. Rain can begin as snow, but by the time it reaches the Earth's surface, it has melted because the temperature closer to Earth is warmer.
