  2. Acid rain - Wikipedia

    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.

  3. Robert Angus Smith - Wikipedia

    en.wikipedia.org/wiki/Robert_Angus_Smith

    Robert Angus Smith FRS (15 February 1817 – 12 May 1884), commonly referred to as Angus Smith, [1] was a Scottish chemist, who investigated numerous environmental issues.He is known for his research on air pollution in 1852, in the course of which he discovered what came to be known as acid rain.

  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. [1]

  5. Black Triangle (region) - Wikipedia

    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.

  6. Laze (geology) - Wikipedia

    en.wikipedia.org/wiki/Laze_(geology)

    Laze is acid rain and air pollution arising from steam explosions and large plume clouds containing extremely acidic condensate (mainly hydrochloric acid), which occur when molten lava flows enter cold oceans. [1] [2] The term laze is a portmanteau of lava and haze.

  7. 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.

  8. Rainwater tank - Wikipedia

    en.wikipedia.org/wiki/Rainwater_tank

    The water was then brought into homes by copper piping. The copper was released by the highly acidic rainwater and caused poisoning in humans. While the plastic tank is an inert container, the collected acid rain could and should be analysed and pH adjusted before being brought into a domestic water supply system.

  9. Snowball Earth - Wikipedia

    en.wikipedia.org/wiki/Snowball_Earth

    The Snowball Earth is a geohistorical hypothesis that proposes that during one or more of Earth's icehouse climates, the planet's surface became nearly entirely frozen with no liquid oceanic or surface water exposed to the atmosphere.
