    en.wikipedia.org/wiki/Acid_rain

    Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH).Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average.

    Turów Power Station, a thermal power station in Bogatynia, Poland Effects of acid rain in the Jizera Mountains in 2006. The Black Triangle (German: Schwarzes Dreieck, Lower Sorbian: Carny tsirozk, Upper Sorbian: Čorny trirózk) is the border region between Germany, Poland and the Czech Republic, long characterized by extremely high levels of pollution.

  4. Freshwater acidification - Wikipedia

    en.wikipedia.org/wiki/Freshwater_acidification

    Diagram depicting the sources and cycles of acid rain precipitation. Freshwater acidification occurs when acidic inputs enter a body of fresh water through the weathering of rocks, invasion of acidifying gas (e.g. carbon dioxide), or by the reduction of acid anions, like sulfate and nitrate within a lake, pond, or reservoir.

    These data have been helpful as baselines for the increasingly sophisticated areas of ongoing research in the forest. HBES has spawned over 2000 scientific papers, perhaps most important a 1968 study that documented the widespread presence of "acid rain". HBRF was designated as a Long-Term Ecological Research (LTER) site in 1988 and has some of ...

  7. Copper Basin (Tennessee) - Wikipedia

    en.wikipedia.org/wiki/Copper_Basin_(Tennessee)

    After the Civil War, smelting operations, which were used to separate sulfur from the copper ore, resulted in acid rain in the area. Combined with the logging of nearby forests to fuel the smelters, this resulted in a massive environmental disaster that left the surrounding landscape barren for more than a century. Several mines, the largest of ...

    Possible explanations for the coal gap include sharp drops in sea level at the time of the Permo-Triassic boundary; [44] acid rain from the Siberian Traps eruptions or from an impact event that overwhelmed acidic swamps; climate shift to a greenhouse climate that was too hot and dry for peat accumulation; evolution of fungi or herbivores that ...

  9. Virga - Wikipedia

    en.wikipedia.org/wiki/Virga

    Sulfuric acid rain in the atmosphere of Venus evaporates before reaching the ground due to the high heat near the surface. [2] Similarly, virgae happen on gas giant planets such as Jupiter. [citation needed] In September 2008, NASA's Phoenix lander discovered a snow variety of virga falling from Martian clouds. [3]
