Essay On Hydrosphere

Hydroshpere

The hydrosphere of a planet refers to all forms of water present on the planet. The water can be in any state liquid, solid or in gas state. It can also be found either underground and out of everyday sight or on the surface and in the air.

Focussing on earth, water in liquid state would be oceans, lakes, rivers, streams and underneath the surface as groundwater and aquifers for example. Water in gas form would refer to water vapour that can be visibly seen in clouds and fog. The solid state in which water can be seen on earth would be ice caps, icebergs and glaciers.

The water that makes up the hydrosphere constantly revolve and moves in and around the earth in a cycle called the water or hydrologic cycle.

Hydrosphere and the water cycle

The deviation of large water sources such as rivers and large dams was scientifically proven to be the main cause of the damage done to aquatic habitats. This caused/includes the damage done to fish population, extinction of endangered species and a huge deal of damage done to

Dynesius and Nilsson 1994) will include the alteration of vegetation that causes downstream habitat effects such as enlargement of floodplains, wetlands and riparian zones. It also causes the collapse of river to ocean estuaries as well as the collapse of river deltas (e.g. Rosenberg et al. 1997), that leads to the water mass loss in rivers, causing a decrease in the quality of the remaining water due to dilution issues of pollution. (NRC 1992, Gillilan and Brown 1997). Dynesius and Nilsson predicted that almost 80% of the 139 of the largest rivers in the northern hemisphere’s discharges are being drastically effected by riverbank fragmentation. This is of great concern considering that the biological populations across the
