A: Nitrogen, oxygen, carbon dioxide, argon.
Humans and other animals inhale oxygen and exhale carbon dioxide. With our population, wouldn't this reduce the atmospheric oxygen level over a period of time? Explain.
A: No, people and animals inhale oxygen and exhales carbon dioxide. Plants convert carbon dioxide into oxygen through photosynthesis.
Describe how the temperature of the atmosphere varies in each of the following regions:
A: Mesosphere is the coldest region of the atmosphere. With altitude to a value of -95C. Stratosphere is -60C with an altitude of 50km. Troposphere is virtually all clouds and water vapor at the top the temperature falls to -45C and above it increases to an altitude of 50km. thermosphere is heated by sun rays and the temperature to over 1000C.
Of what important is the atmospheric ozone layer?
A:The ozone layer in the stratosphere acts as an umbrella that shields life from harmful ultraviolent radiation from the Sun by absorbing most of the short wavelength of this radiation.
From what source does the atmosphere receive most of its direct heating, and how is the overall heating accomplished?
