hydrosphere covers how much of earth's lithosphere?
71 %
earth's lithosphere is divided into several rigid tectonic plates that migrate across the surface over many millions of years. about 71% of earth's surface is covered with water, mostly by oceans. the remaining 29% is land consisting of continents and islands that together contain many lakes, rivers and other sources of water that contribute to the hydrosphere. the majority of earth's polar regions are covered in ice, including the antarctic ice sheet and the sea ice of the arctic ice pack. earth's interior remains active with a solid iron inner core, a liquid outer core that generates the earth's magnetic field and a convecting mantle that drives plate tectonics.

earth's lithosphere includes the crust and the uppermost mantle, which constitute the hard and rigid outer layer of the earth. the lithosphere is subdivided into tectonic plates. the uppermost part of the lithosphere that chemically reacts to the atmosphere, hydrosphere, and biosphere through the soil forming process is called the pedosphere. the lithosphere is underlain by the asthenosphere which is the weaker, hotter, and deeper part of the upper mantle. the lithosphere-asthenosphere boundary is defined by a difference in response to stress: the lithosphere remains rigid for very long periods of geologic time in which it deforms elastically and through brittle failure, while the asthenosphere deforms viscously and accommodates strain through plastic deformation.
