Question

freshwater is vital for life on earth. where do we find most of earths freshwater? locked away as ice caps and glaciers, especially at the poles evaporating from the earths surface and forming clouds in the vast oceans, which cover most of the planets surface deep underground in aquifers, which are difficult to access

Explanation:

Most of Earth's freshwater is stored in ice caps and glaciers, especially at the poles. Oceans contain saltwater. Evaporating water forms clouds but isn't the main reservoir. Aquifers hold some freshwater but less than ice caps/glaciers.

Answer:

locked away as ice caps and glaciers, especially at the poles
