The tests were carried out in the municipality of Hengelo, where the busy Castorweg road was resurfaced last fall. As part of the project, around 1,000 square meters of the road's...

Acid Rain
2013-04-01 10:21:17

Acid rain is any form of precipitation that is unusually acidic, meaning that is possesses high levels of hydrogen ions. It can have harmful effects on aquatic animals, plants, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules within the atmosphere to produce acids. Nitrogen oxides can be produced naturally by lightening strikes. Sulfur dioxide can be produced naturally by volcanic eruptions. The chemicals that are...

Rain is a type of liquid precipitation. It is defined as condensation of atmospheric water vapor that forms into drops that become heavy enough to fall, and often making it to the surface. Rain is the primary source of most of the fresh water in the world. Rain provides suitable conditions for diverse ecosystems, water for power sources and for crop irrigation. Not all rain reaches the surface. Some rain evaporates as it falls, especially through dry air. This type of rainfall is known as...
