Answer:
The total amount of water on the planet that is present in the atmosphere at any given time is about 0.001% of the total water found on Earth. This atmospheric water is responsible for all storms.
If by in storage we mean in groundwater then the percentage would be 1.69.
Explanation:
The overwhelming majority of all water on our planet resides in the oceans. These hold about 96.5% of the total.
If we only consider freshwater (water with no salt) then the greatest storage areas are ice caps, glaciers, and groundwater aquifers.
