ATM 1050 Exam 1 With
Solution
Layers of the atmosphere...
trophosphere - ANSWER layer of Earth's amosphere closest to Earth's surface
(where weather takes place and where most pollution occurs)
stratosphere - ANSWER 12 to 50 km, Ozone held here, absorbs UV radiation
mesosphere - ANSWER 3rd layer of the atmosphere
thermosphere - ANSWER the region of the atmosphere above the
mesosphere and below the height at which the atmosphere ceases to have
the properties of a continuous medium. The thermosphere is characterized
throughout by an increase in temperature with height.
what aspect of weather is most indicative of future weather? - ANSWER wind
speed and direction
why does 99% of the atmosphere reside near earth's surface? - ANSWER
gravity and compressibility
composition of the atmosphere - ANSWER 78% nitrogen, 21% oxygen, 1%
other (argon)
how does carbon dioxide enter atmosphere? - ANSWER Decay of Vegetation
Volcanic Eruption
Exhalation of Animal Life
, Burning of Fossil Fuels
how does carbon dioxide get removed from atmosphere? - ANSWER
photosynthesis, vegetation, oceans
Pros and Cons of Ozone - ANSWER Pros
- absorbs radiations
- natural shield (car window)
Cons
- eye/throat irritation
- vegetation damage
Aerosols - ANSWER tiny solid particles or liquid droplets that remain
suspended in the atmosphere for a long time (dust/ash/salt)
pollutants - ANSWER Harmful substances in the air, water, or soil (auto/fuel
emission)
Weight - ANSWER the force of gravity on an object
