A
Precipitation that is unusually acidic, typically with a pH level below 5.6, due to the emission of sulfur dioxide and nitrogen oxide gases into the atmosphere, which react with water molecules to form sulfuric acid and nitric acid.
Empieza por
B
The industrial sector involved in the production of large quantities of chemicals and chemical products, including petrochemicals, polymers, specialty chemicals, and basic inorganic chemicals, such as chlorine, ammonia, and sulfuric acid. Three words.
Empieza por
C
A long-term alteration in global or regional climate patterns, primarily caused by the increased emission of greenhouse gases from human activities. Two words.
Empieza por
D
Action refers to the clearing or removal of forested areas that can lead to a variety of negative impacts on the environment, including habitat loss, soil erosion, water pollution, climate change, and the loss of biodiversity.
Empieza por
E
Refers to the natural world and surroundings in which living organisms exist, including both physical and biotic factors. Acid rain and climatic change are two problems that afect it.

F
A shorthand way of representing a molecule using symbols and subscripts to indicate the types and numbers of atoms present.
Empieza por
G
A primary product of the petroleum industry and is refined from crude oil in oil refineries.
Empieza por
H
An organic compound composed of only hydrogen and carbon atoms, often used as a fuel source.
Empieza por
I
A type of electromagnetic radiation with longer wavelengths than visible light, which plays an important role in the "greenhouse effect" by trapping heat in the atmosphere, contributing to the warming of the planet. Two words.

Empieza por
N
Produced primarily from human activities such as combustion of fossil fuels, which include transportation, power generation, and industrial processes, play a significant role in the formation of acid rain.
Empieza por
O
A gas molecule made up of three oxygen atoms. It is a naturally occurring component of the Earth's atmosphere and is found primarily in the stratosphere, where it helps to protect the planet from harmful ultraviolet radiation from the sun.
