Characteristics of the Atmosphere

Define atmosphere

• A gas molecule made up of three oxygen atoms

• A mixture of gases that surrounds a planet, moon, or other celestial body

• The force per unit area that is exerted on a surface by the weight of the atmosphere

• The lowest layer of the atmosphere, in which the temperature drops at a constant rate as altitude increases; the part of the atmosphere where weather conditions exist

Describe the composition of dry air at sea level.

• 78% water vapor, 21% carbon dioxide, 0.9% argon, and less than 0.1% other gases such as oxygen

  Answer option 3

• 21% nitrogen, 78% oxygen, 0.9% argon, and less than 0.1% other gases such as carbon dioxide

• 78% nitrogen, 21% oxygen, 0.9% argon, and less than 0.1% other gases such as carbon dioxide

  Answer option 3

• 78% mercury , 21% oxygen, 0.9% water vapor, and less than 0.1% other gases such as carbon dioxide

  Answer option 3

Define ozone

• The coldest layer of the atmosphere, between the stratosphere and the thermosphere, in which temperature decreases as altitude increases

• The force per unit area that is exerted on a surface by the weight of the atmosphere

• A gas molecule made up of three oxygen atoms

• The lowest layer of the atmosphere, in which the temperature drops at a constant rate as altitude increases; the part of the atmosphere where weather conditions exist

What is the order of the layers of the atmosphere from the ground up?

• Thermosphere, Troposphere, Ozone, Stratosphere, Mesosphere

• Troposphere, Stratosphere, Thermosphere, Mesosphere

• Troposphere, Stratosphere, Thermosphere, Mesosphere, Ozone

• Troposphere, Stratosphere, Mesosphere, Thermosphere

Define electromagnetic spectrum

• All of the frequencies or wavelengths of electromagnetic radiation

• The fraction of solar radiation that is reflected off the surface of an object

• The warming of the surface and lower atmosphere of Earth that occurs when CO2 , water vapor, and other gases in the air absorb and reradiate infrared radiation

• The transfer of energy as heat through a material

Define jet stream

• Prevailing winds that blow from east to west between 60° and 90° latitude in both hemispheres

• A narrow band of strong winds that blow in the upper troposphere

• Prevailing winds that blow from east to west from 30° latitude to the equator in both hemispheres

• The curving of the path of a moving object from an otherwise straight path due to Earth’s rotation

What is the ionosphere?

• The lower part of the thermosphere

• A part of the ozone

• The outer layer of the mesophere

• Where air pollution is formed

Define convection

• The movement of matter due to differences in density that are caused by temperature variations; can result in the transfer of energy as heat

• The curving of the path of a moving object from an otherwise straight path due to Earth’s rotation

• All of the frequencies or wavelengths of electromagnetic radiation

• The uppermost layer of the atmosphere, in which temperature increases as altitude increases; includes the ionosphere
