Answer:
The hydrosphere, including all the waters on the Earth’s surface, is interconnected with the other ‘spheres’ in the Earth system, that is the geosphere (lithosphere and atmosphere), the biosphere, and the human-related anthroposphere. Water, the most widespread substance in the environment of our planet, is available, in liquid, solid, and vapor states, everywhere on Earth, albeit its abundance largely differs in space and time.
