Land covered by water, wetland and bareland accounted for a relatively low proportion of total land cover in most of the EU Member States in 2015. Hills & mountains help the wet air to rise up in order to increase density of clouds, which ultimately rains. 10% of the world is covered by glaciers, and a further 19% is barren land – deserts, dry salt flats, beaches, sand dunes, and exposed rocks. Some folks in the know have estimated that Urban land use at this point is closer to 2.4% of the earth’s land area and they speculate that the 3% figure is being used to cover the uncertainty. https://www.quora.com/How-much-land-on-Earth-in-terms-of-percentage-is-populated-by-humans. eNotes.com will help you with any book or any question.

The Food and Agriculture Organization of the United Nations (FAO) defines forests as "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds in situ. Just over 2/3 of the Earth is ocean. This is down from the pre-industrial area of 5.9 billion hectares. “90% of Earth is covered by humans”!
