Glaciology (physical geography): Which type of glaciers are the largest on Earth by area and volume? Consider the distinction between alpine/mountain glaciers and vast ice sheets. Choose the correct type.

What is being asked? Identify the largest glacier type by scale.

Concept/ApproachContinental glaciers, i.e., ice sheets (like those in Antarctica and Greenland), cover vast continental areas and hold the majority of Earth’s freshwater ice. Alpine/mountain glaciers are comparatively small and confined to mountain valleys; piedmont glaciers spread at mountain bases but are far smaller than ice sheets.
