Question

Development activities on the hydrosphere cause

Answer 1

Hint: The hydrosphere is the total mass of water found on, beneath, and above the earth's surface. The amount of water on the planet is believed to be 1386 million cubic kilometres. Groundwater, seas, lakes, and streams all include liquid and frozen water. Oceans encompass over 75% of the Earth's surface or 361 million square kilometres.

Complete answer:
The hydrologic cycle is being severely impacted by contemporary society's activities. The discharge of hazardous chemicals, radioactive compounds, and other industrial wastes, as well as the seepage of mineral fertilisers, herbicides, and pesticides into surface and subsurface aquatic systems, are disrupting the dynamic steady state. Petroleum spills, both accidental and intentional, poor sewage disposal, and thermal pollution all have a negative impact on the hydrosphere's quality.

The current debate centres on three key issues: eutrophication, acid rain, and the accumulation of so-called greenhouse gases. Each is an example of human intervention in the hydrologic cycle and its far-reaching consequences. Water pollution (also known as aquatic pollution) occurs when water bodies become contaminated as a result of human activity. Lakes, rivers, oceans, aquifers, and groundwater are examples of water bodies. When pollutants are introduced into the natural ecosystem, water contamination occurs. Inadequately treated wastewater, for example, can degrade aquatic ecosystems when released into natural water bodies.

Water contamination is caused by a variety of chemicals and microorganisms, as well as physical factors. Organic and inorganic compounds can be contaminants. Polluted water can also be a result of high temperatures. The use of water as a coolant by power plants and industrial firms is a frequent source of thermal pollution. Increased water temperatures lower oxygen levels, which can kill fish and change the makeup of food chains, diminish species biodiversity, and encourage the invasion of new thermophilic species.

Note: Surface water pollution and groundwater contamination are two types of water pollution. Water pollution is divided into two categories: marine pollution and nutrient contamination. There are two types of sources of water pollution: point sources and nonpoint sources. A single identified source of pollution, such as a storm drain or a wastewater treatment facility, is referred to as a point source. Non-point sources, such as agricultural runoff, are more diffuse. Pollution is the outcome of a long-term cumulative impact. Polluted water bodies can affect all plants and organisms that live in or are exposed to them. Individual species may be harmed, as well as the natural ecological communities in which they live.
