  • is removed from the atmosphere by photosynthesis.
  • is not present in significant amounts in the atmosphere of Venus.
  • is being removed from the atmosphere faster than it is being inputted.

Questão 115

Questão
The mass of a given substance contained in a unit of volume is referred to as which of the following?
Responda

The highest temperatures are typically found in the
Responda
  • stratosphere.
  • troposphere.
  • thermosphere.
  • mesosphere

Questão 117

Questão
The "stratosphere" warms because of
Responda
  • the injection of moisture by meteors.
  • the injection of moisture by high-flying jet aircraft.
  • dust and dirt deposited by volcanoes
  • the interaction of ozone and ultraviolet light.

Questão 118

Questão
An inversion
Responda
  • never occurs in the atmosphere.
  • refers to a temperature increase with height.
  • promotes upward motion in the atmosphere
  • refers to a temperature increase with height and inhibits upward motion in the atmosphere.

Questão 119

Questão
The difference between the atmosphere's "permanent" gasses and "variable" gasses is that
Responda
  • permanent gasses exhibit a constant proportion from the earth's surface to higher reaches of the atmosphere.
  • variable gasses are dependent on storms for world-wide dispersion.
  • permanent gasses exchange rapidly between the atmosphere and the biosphere.
  • variable gasses are so called because of their horizontal displacement.

Questão 120

Questão
