Glaciers : āĻšāĻŋāĻŽāĻŦāĻžāĻš



Glaciers : A glacier is a large mass of ice that moves slowly over land. It forms when snow collects in the accumulationhttps://images.openai.com/static-rsc-4/idGCCbkWtoWWNBxiZHhCEUe8fo_M2OK36Ha-dN3f4sIURYg1sSGlZK7pUG_f77piA6P2koC7VJ-52vKzbHlE9FFZB2NP7sJPVcJ1LZQIaIwsDh9UhFDm71GG8X_2TopJCPMwRNEgL1EXrf9XqUygQFDz_Dur3Cy1-L43EArrGZa0971jsykZNrrWiiI7RhIU?purpose=fullsize zone and gradually turns into ice. The glacier then flows in a particular direction, known as the ice flow direction. As it moves, the lower part called the ablation zone starts melting. The front end of a glacier is known as the snout. There are two main types of glaciers: valley glaciers and continental glaciers. Valley glaciers flow through mountain valleys, such as the Gangotri Glacier, while continental glaciers are large ice sheets covering vast land areas, like in Antarctica.
