| acid rain Rain having a pH less than 5.6. The acidity results from chemical reactions occurring when water, sulphur dioxide, and nitrogen oxides, generally released by industrial processes, are chemically transformed into sulphuric and nitric acids | kwaśny deszcz (deszcz o pH poniżej 5.6) |
| rain forest A forest of broad-leaved, mainly evergreen, trees found in continually moist climates in the tropics, subtropics, and some parts of the temperate zones | lasy deszczowe (wiecznie zielone lasy liściaste, występujące na obszarach o dużej wilgotności, głównie w strefach klimatu tropikalnego i subtropikalnego, miejscami w strefie klimatu umiarkowanego) |
| rain water Water which falls as rain from clouds | woda deszczowa (woda spadająca z chmur w postaci deszczu) |
| rain water sewer system Channels for clearing away rain water | kanalizacja deszczowa (system kanalizacyjny służący odprowadzaniu wód opadowych) |
| tropical rain forest The most valuable and the richest ecosystem on Earth. It plays a critical part in the Earth's life support systems and house 50%, and possibly as much as 90%, of all the species on Earth. It is a key storehouse of foods, oils and minerals, and a source of ingredients that make up a range of medical treatments. It also represents home and livelihood for many people. However, more than half of the rainforests have disappeared, chopped down for valuable tropical hardwoods, or cleared to provide areas for cattle grazing or human habitation. The forests play an important part in climate patterns, and deforestation is thought to be responsible for 18% of global warming. Furthermore, as they disappear there is also an albedo effect - a damaging increase in the sunlight reflected - which affects wind and rainfall patterns | tropikalny las deszczowy (najcenniejszy i najbogatszy ekosystem na Ziemi, występujący na obszarach tropikalnych) |
