New cards
15
Ozone
________: is found in two layers in the atmospheric.
New cards
16
Ozone depleting substances
________: including halogenated organic gases, are used in aerosis, plastics, and such to cause halogen atoms from these pollutants to increase destruction of ozone in a repetitive cycle so allowing more ultraviolet to reach the earth.
New cards
17
solar radiation
Incoming ________ is mostly made up of visible light, ultraviolet light and infrared heat.
New cards
18
Stratospheric Ozone

New cards
19
Ozone

New cards
32
**Primary Pollutants**
from the combustion of fossil fuels include carbon monoxide, carbon dioxide, black carbon/soot, unburned hydrocarbons, oxides of nitrogen, and oxides of sulfur
New cards
33
**secondary pollutants**
are formed when primary pollutants undergo a variety of reactions with other chemicals already present in the atmosphere.
New cards
34
**Smog**
is a complex mixture of primary and secondary, of which tropospheric ozone is the main pollutant
New cards
35
**Thermal Inversions**
occur due to a lack of air movement when a layer of dense, cool air is trapped underneath a layer of dense, warm air
New cards
36
**Pollution management strategies**
include altering human activities to consume less. This will help decrease harmful emissions released into the environment
New cards
37
**Acid deposition**
general term for acid coming down from the air
New cards
38
Replacing
switching to the use of renewable energy (reducing the use of fossil fuels), use less automobiles and more public transportation, increase energy efficiency
New cards
39
Regulate
install catalytic converters to reduce carbon emissions produced by factories and automobiles
New cards
40
Restoring
add lime to forestry plantations to increase the use of natural resources and forests (decreases the need to export and import which is harmful for the environment)
