Biology Questions and Answers
it is less dense, the warm air tends to
move towarof the atmosphds higher and colder strataere. Such movement
helps the dispersion of pollutants.
- Does thermal inversion
occur in the winter or in the
summer?
Pollutant low occurs in the winter. altitude thIn this peermal invriod ofersion
the year the the natural upward msun heats thove of warm e soil less anair d
decreases. Therefore the pollutantsform a low altitude layer between the (^)
cold air layer near the ground and
another pollutant layer layer oover industrial areas orf warmer air above. The
big urban concentrations reduces the
penetration oair bellow takes an even longer time tof the sun's energy and the
warm.
- Why does thermal
inversion increases air
pollution? What harm can
thermal inversion cause to
humans?
Thermal altitude a layer inversion of pollutants that woconfines at low (^) uld
have been dispersed by the natural
upward move of warm air. Tparticles present in the atmosphe solidhere
cause health problems, like the
exacerbation pulmonary diseases, coof asthmaugh, respiratory and other (^)
unease and ocular pollution can also triggdischarger thees; later th e
appearance of cardiovascular and
neoplastic diseases.
- What is the role of the
ozone layer for living beings?
Ozone, O3, is a gas of the atmosphere
that filters usun disallowinltravioletg most of radiation fthat radiationrom the
from reaching the surface of the planet.
Ultravioletbeings because it is a m radiation is hautagen and canrmful for living
cause cancer (mainly skin cancer), other
DNA mutations and even burns. - What are the main
chemical compounds that
destroy the ozone layer?
The mains chemical compounds that
destroy thchlorofluorocarboe ozone layer ns, or freons,are the CFCs,
substancesrefrigerators, aircon used in the past inditioners a (^) nd spray
cans.
Chlorofluorocarthe high atmosphbons react with ozone inere releasing
molecular oxyamount of ozone in the atmosphegen and therefore there is (^)
reduced.
Another substance tozone layer is methyl bhat destroys thromide, used ine (^)
agricultural insecticides.
- What is nuclear pollution?
