The structure of Atmosphere 4.1
What is the name of the atmosphere layer that is closest to earth
Troposphere
Define ozone depletion
reduction in the concentration of ozone in the ozone layer.
What type problems can pollution/smog cause
Respritory problems
Where is the ozone whole located
The ozone hole is located over Antarctica
What is the most abundant gas in the atmosphere
Nitrogen
so2 and nox
WHat is the global issue caused by green houses which leads to increasing temperatures
Climate change/global warming
What is the stratosphere
An atmosphereic layer containing the ozone layer and located over the troposhere
What is the ozone Layer?
It acts as a protective shield, absorbing harmful ultraviolet (UV) radiation from the sun, particularly UVB rays. This protection is crucial for life on Earth, shielding us from the potentially damaging effects of UV radiation.
What chemical causes the ozone whole
What is smog and what causes it?
Smog isa hazy, polluted cloud formed by the interaction of air pollutants, primarily ground-level ozone and particulate matter, with sunlight and other atmospheric conditions.
Define fossil fules
Fossil fuels are naturally occurring, combustible materials formed from the fossilized remains of ancient organisms
Define The natural green house affect
The natural greenhouse effect is the process by which the Earth's atmosphere traps heat from the sun, keeping the planet warm enough to support life
Defnine acid rain
Acid rain is precipitation with a pH value of less than 6 (see Section 4.8). The acidity results from
burning fossil fuels in factories and power stations, which release sulfur dioxide and nitrogen oxides
into the atmosphere. Vehicle emissions add further nitrogen oxides. This is dry deposition. If these
gases mix with water vapour and oxygen in the atmosphere, weak solutions of nitric and sulfuric
acids are created, which can then be moved by winds. These solutions will eventually fall to Earth
as acid rain and can occur at some distance from the source. This is wet deposition.
What causes acid rain
Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air .
Name one case study studied in class about smog
London smog
Name all layers of the atmosphere ( in order)
troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
Define Inversion
Usually, air gets cooler as you go higher in the atmosphere. However, sometimes a layer of warm air sits above cooler air near the ground, trapping it.
Name one case study studied in class about acid rain
China
What is the coroisisphere and what are the charerteristics
PRANK DOESNT EXIST
