Acid rain was an environmental hyperbole covering the effect of sulfur dioxide and nitrogen dioxide gasses being washed out of the atmosphere by rainfall. Downstream from coal-fired power generation and metal reduction processes, these gasses were part of the gas stack chemistry; sourced as minor constituents of the process coal. The pollutants were only measured in ppm quantities in major smoke stacks … famously I measured 200 ppm in the air from the Inco Superstack, measured over Toronto air space. Ontario has no coal plants or stacks left after environmentally forced decommissioning.

? 3. Explain why Surtsey provided ideal conditions for studying primary succession:
Delicious77 [7]

Answer:

Due to newly formed land.

Explanation:

Surtsey provided ideal conditions for studying primary succession because due to volcanic eruption all the vegetation and living organisms are destroyed from the surface and the land has no vegetation. Primary succession only occurs when the land is colonized for the first time after the formation of land due to natural disaster such as volcanic eruption etc. So we can say that Surtsey provided the conditions for observing primary succession.
