Within the Hydrosphere, Fishes and Fresh waters: Availability and Sustainability in the Ecosystem:- Avoaja, Diane A.
ABSTRACT
THE
HYDROSPHERE: The hydrosphere refers to the water on or surrounding the surface
of the globe, as distinguished from those of the lithosphere (the solid upper
crust of the earth), and the atmosphere (the air surrounding the earth). More
specifically, the hydrosphere includes the region that has all the earth's
liquid water, frozen and floating ice, water in the upper layer of soil, and
the small amounts of water vapour in the earth's atmosphere. The earth's water
has six major reservoirs in which water resides. These include the oceans; the
atmosphere; surface water (including water in lakes, streams, rivers, and water
held in the soil); ground water; snow; and ice. My attention is focused on the
3rd, i.e. surface water (freshwaters/inland waters). Fig. 1 shows the
composition of the earth's water supply. Ocean /salt water occupies 97.5% while
freshwater/inland water occupies only 2.5%. The quality of natural water in the
various reservoirs depends on a number of interrelated factors. These factors
include geology, climate, topography, biological processes, land use and the
time the water has been in residence.
