The largest reservoir of water on Earth is the oceans, containing about 97% of all water. After oceans, the next major source of water is glaciers and polar ice caps, which hold approximately 1.7% of the Earth's total water, primarily as freshwater.

Explanation:

The distribution of water on Earth is as follows:

1. Oceans: ~97% (saline water)

2. Glaciers and polar ice caps: ~1.7% (freshwater)

3. Groundwater: ~1.7% (freshwater)

4. Lakes, rivers, and atmospheric vapor: Smaller percentages.

Therefore, after ocean water, glaciers and polar ice represent the largest reservoir.
