Is there such a thing as red snow?
Red snow is found in many parts of the world, when tiny plants grow over the snow and ice. Microscopic algae growing on the surface of snow and ice can give them a red colour. This rare event happens when the weather warms up slightly, and the algae that have been dormant throughout the cold period suddenly start to grow again.

What are glaciers?
Glaciers are large masses of ice that form on land and move slowly under their own weight. They are found in cold mountainous places or Polar Regions. Some glaciers are huge continuous sheets of ice, such as those covering Antarctica and Greenland. But most are rivers of ice that move slowly through valleys until they melt and become rivers. Such glaciers are common in the Himalayas, Alps and Rocky Mountains. Because of its enormous weight a glacier scrapes off large amounts of rock and debris, wearing away the valley floor and sides until it carves out a deep ‘U-shaped’ valley. Glaciers formed the deep fjords that line the coast of Norway.
