Accumulation Zone
Where snowfall and other misoter will fall and increase the size of the glacier

there is a decrees in the size of the glacier thourge melting or sublamtion or calfing
Equilibrium line
the line bwteen accumulstion zone and ablation zone
Crevasses
virtical crackes that devolope in glacier
Striation
