Answer
  • water vapor
  • oxygen
  • nitrogen
  • carbon dioxide

Question 113

Question
Water vapor
Answer
  • can comprise up to five percent of the total mass of the atmosphere.
  • has evaporation as its primary source.
  • does not absorb infrared radiation.
  • typically increases in concentration at higher altitudes within the troposphere.

Question 114

Question
Carbon dioxide
Answer
  • comprises up to two percent of the atmospheric gases.
  • 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.

Question 115

Question
The mass of a given substance contained in a unit of volume is referred to as which of the following?
Answer
  • Density
  • Escape velocity
  • Weight
  • Pressure

Question 116

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

Question 117

Question
The "stratosphere" warms because of
Answer
  • 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.

Question 118

Question
An inversion
Answer
  • 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.

Question 119

Question
The difference between the atmosphere's "permanent" gasses and "variable" gasses is that
Answer
  • 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.

Question 120

Question
Temperatures generally decrease with height in which layers of the atmosphere?
Answer
  • Stratosphere and troposphere
  • Troposphere and mesosphere
  • Stratosphere and thermospherE
  • Mesosphere and stratosphere

Question 121

Question
This is NOT a variable gas.
Answer

Question 122

Question
Which of the following gases are crucial to the existence of all forms of life?
Answer
  • oxygen
  • carbon dioxide
  • argon
  • nitrogen

Question 123

Question
Which of the following will increase given an increase in pressure?
Answer
  • volume
  • density
  • mass
  • both mass and volume

Question 124

Question
Which of the following is the primary difference between weather and climate?
Answer
  • Weather deals with long-term changes, and climate does not.
  • They are both the same.
  • Weather deals with the instantaneous effects on Earth, whereas climate is over a period of 30 years.
  • Climate deals with only temperature patterns over the span of a week.
