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.
Monsoons are large-scale sea breezes which occur when the temperature on land is significantly warmer or cooler than the temperature of the ocean. Most summer monsoons or southwest monsoons (Filipino: Habagat) have a dominant westerly component and a strong tendency to ascend and produce copious amounts of rain (because of the condensation of water vapor in the rising air).
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.

When an acid is dissolved in water, the pH will be less than 7, while a base, or alkali, will have a pH greater than 7. A strong acid, such as hydrochloric acid, at concentration 1 mol dm −3 has a pH of 0, while a strong alkali like sodium hydroxide, at the same concentration, has a pH of 14. Since pH is a logarithmic scale, a difference of ...
The principal cause of alkaline rain are emissions from factories and waste deposits. Mineral dust containing large amounts of alkaline compounds such as calcium carbonate can also increase the pH of precipitation and contribute to basic rain. [3] Alkaline rain can be viewed as opposite to acid rain.
This compound causes rainfall pH to be around 5.0–5.5. When rainfall has a lower pH than natural levels, it can cause rapid acidification of soil. Sulfur dioxide and nitrogen oxides are precursors of stronger acids that can lead to acid rain production when they react with water in the atmosphere
The Climate of Cebu is a tropical wet and dry climate. There are two seasons in Cebu - the wet season and the dry season. [1] Cebu has three different climates, based on the distribution of rainfall, with the most prevalent ones being Am and Af and a very minor area of Aw.
Philippines map of Köppen climate classification zones. The Philippines has a tropical maritime climate that is usually hot and humid. There are three seasons: tag-init or tag-araw, the hot dry season or summer from March to May; tag-ulan, the rainy season from June to November; and tag-lamig, the cool dry season from December to February.
