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.
The fruit is referred to as the arctic kiwi, baby kiwi, cocktail kiwi, dessert kiwi, grape kiwi, hardy kiwifruit, kiwi berry, northern kiwi, Siberian gooseberry, or Siberian kiwi, [2] and is an edible, berry- or grape-sized fruit similar to kiwifruit in taste and appearance, but is green, brownish, or purple with smooth skin, sometimes with a red blush.
Kiwifruit (often shortened to kiwi outside Australia and New Zealand), or Chinese gooseberry, is the edible berry of several species of woody vines in the genus Actinidia. [ 1 ] [ 2 ] The most common cultivar group of kiwifruit ( Actinidia deliciosa 'Hayward') [ 3 ] is oval, about the size of a large hen's egg : 5–8 centimetres (2–3 inches ...
Kiwi eggs can weigh up to one-quarter the weight of the female. Usually, only one egg is laid per season. The kiwi lays one of the largest eggs in proportion to its size of any bird in the world, [34] [a] so even though the kiwi is about the size of a domestic chicken, it is able to lay eggs that are about six times the size of a chicken's egg ...

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.
Over the contiguous United States, total annual precipitation increased at an average rate of 6.1 percent per century since 1900, with the greatest increases within the East North Central climate region (11.6 percent per century) and the South (11.1 percent). Hawaii was the only region to show a decrease (−9.25 percent). [89]
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.
