| Annual Equilibrium Line (ELA) is... | A point on the glacier (on the cross-section, along the stakes line) where the balance is zero – accumulation=ablation. |
| Small glacier that flows into bigger one. | Tributary glacier |
| A part of the glacier that moves over a steep drop, faster than rest of the ice. | Icefall |
| Where does majority of ice cores come from? | Greenland and Antarctica |
