Question

Describe how human induced changes in the atmosphere impact at least one other sphere (ex hydrosphere, geosphere, biosphere, cryosphere).

Answer 1

Step-by-step explanation:

Human induced changes have greatly altered the nature of the hydrosphere for a long time now.

The hydrosphere is the water blanket round the earth. It accounts for 70% of the total surface area of the earth. The rest is the continent.

• One of the human induced changes to the atmosphere originates from global warming.
• Global warming is the rise in earth's temperature. It results from greenhouse effects.
• When greenhouse gases like carbon monoxide and methane are produced in excess, they trap outgoing solar radiation anomalously.
• These gases helps to buffer the temperature on earth. When their concentration is too much, they will increase the temperature more than usual.
• This will eventually lead to melting of polar ice and inundation of the hydrosphere with melt water.
• Humans are one the chief contributors to the production of the greenhouse gases.

Answer 2

Human induced changes could impact all of the mentioned spheres. Below I have explained the changes for hydrosphere as an example.

Step-by-step explanation:

Hydrosphere plays an important role for all forms of life on Earth. Hydrosphere includes all forms of water on the planet, Humans are impacting the hydrosphere due to their anthropogenic activities that leads to aquatic pollution. Further, increasing human's population are subject to urbanization and industrialization. More industries are being installed and ultimately more pollution is happening. If we look at the example of oil industry, every year, oil industry globally produces approximately 33.6 million barrels per day of oil-contaminated water during drilling, extraction and refining processes. Crude oil contains significant proportions of hydrocarbons including alkanes, aromatics, polycyclic aromatic hydrocarbons, as well as non-hydrocarbons such as naphthenic acids. If these compounds are released into the environment as wastewater without any treatment, they come in contact with the living organisms and cause several disease because of their carcinogenic, neurotoxic, or genotoxic nature. At first, it affects the aquatic life, then those aquatic organisms which are being eaten by secondary or tertiary consumers, they will also get affected.

If we look carefully, organisms within aquatic environment comes in the biosphere and hence, biosphere is also being affected. In fact, all of these spheres are somehow connected and disturbance of one sphere put a pressure on other one.
