The main evidence of glaciers melting is the melting of Alaska's Muir glaciers.
Explanation:
The main reason of melting of glaciers is the increase in temperature due to more emissions of greenhouse gases such as carbondioxide and methane gases. These greenhouse gases trap reflected solar radiation which increases the atmospheric temperature cause global warming. This global warming is responsible for the increase in sea level due to glaciers melting.
The columns on the periodic table are called groups or families. The elements in the same group have similar properties. One of these particles is electrons.
