Why Do We See Snow on High Mountains During Summer?
We often see snow on high mountaintops during the summer because the temperature never gets warm enough for all the snow to melt. It is usually much cooler in the mountains than down in the lower valleys.
This is because the higher you go, the thinner the air becomes. The thin mountain air cannot absorb so much of the sun’s heat as can the air at lower levels.
A part of the snow, no matter how cold the climate, will evaporate in the sun. But where a great deal of snow piles up on very high mountains, the heat of the summer is not sufficient to melt it all.
Some mountains reach higher than the clouds. The higher the place is above sea level the colder it will be.
