LE2

Question 1

Precipitation abnormally high in sulfuric and nitric acid content that is caused by atmospheric pollutants.

Answer 1

Acid Precipitation

Question 2

A rain or any other form of precipitation that is unusually acidic, meaning that it possesses elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals and infrastructure.

Answer 2

Acid rain

Question 3

It is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids.

Answer 3

Acid rain

Question 4

It is a generic name for Air Pollution Control Equipment (APC) that is designed around the use of engineered fabric filter tubes, envelopes or cartridges in the dust capturing, separation or filtering process.

Answer 4

Baghouse

Question 5

These are tiny air sacs within the lungs where the exchange of oxygen and carbon dioxide takes place.

Answer 5

Alveoli

Question 6

It is a naturally occurring chemical compound composed of two oxygen atoms each covalently double bonded to a single carbon atom

Answer 6

Carbon Dioxide

Question 7

It is historically defined as “the total sets of greenhouse gas emissions caused by an organization, event, product or person”

Answer 7

Carbon footprint

Question 8

It is a form of emissions trading that specifically targets carbon dioxide (calculated in tonnes of carbon dioxide equivalent or tCO2e) and it currently constitutes the bulk of emissions trading.

Answer 8

Carbon trading

Question 9

These are trails left in the sky by high-flying aircrafts that are believed to have contained chemicals or biological input

Answer 9

Chemtrails

Question 10

It is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time

Answer 10

Question 11

It is an area of closed, circular fluid motion rotating in the same direction as the Earth.

Answer 11

Cyclones

Question 12

It is a filtration device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit.

Answer 12

Electrostatic precipitation

Question 13

These are made up of fallen snow that, over many years, compresses into large, thickened ice masses. It form when snow remains in one location long enough to transform into ice.

Answer 13

Glaciers

Question 14

It is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.

Answer 14

Greenhouse effect

Question 15

It is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect.

Answer 15

Greenhouse gas

Hydrocarbon

Question 20

These are produced synthetically and are used primarily as refrigerants

Answer 20

Hydrofluorocarbon

Question 21

It is a colorless gas with the characteristic foul odor of rotten eggs; it is heavier than air, very poisonous, corrosive, flammable, and explosive.

Answer 21

Hydrogen Sulfide

Question 22

It is an international treaty, which extends the 1992 United Nations Framework Convention on Climate Change (UNFCCC) that commits State Parties to reduce greenhouse gases emissions, based on the premise that (a) global warming exists and (b) man-made CO2 emissions have caused it.

Answer 22

Kyoto Protocol

Question 23

A colorless, odorless flammable gas that is the main constituent of natural gas. It is the simplest member of the alkane series of hydrocarbons.

Answer 23

Methane

Question 24

A cloud of tiny water droplets suspended in the atmosphere at or near the earth’s surface limiting visibility, but to a lesser extent than fog; strictly, with visibility remaining above 1.5 miles (1 km).

Answer 24

Mist

Question 25

It is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion.

Answer 25

Montreal Protocol

Question 26

It is an instrument for measuring concentration of suspended particulates in a liquid or gas colloid. It measures suspended particulates by employing a light beam (source beam) and a light detector set to one side (often 90°) of the source beam.

Answer 26

Nephelometer

Question 28

It is simply defined as reduction of unwanted ambient sound or noise

Answer 28

Noise cancellation

Question 29
