Unit 3Earth’s Atmosphere Lesson 1 The Atmosphere Lesson 2 Energy Transfer Lesson 3 Wind in the Atmosphere
a mixture of gases that surrounds a planet, moon, or other celestial body atmosphere
the measure of the force with which air molecules push on a surface air pressure
the uppermost layer of the atmosphere, in which temperature increases as altitude decreases thermosphere
the layer of the atmosphere between the stratosphere and the thermosphere and in which temperature decreases as altitude decreases mesosphere
the layer of the atmosphere that is above the troposphere and in which temperature increases as altitude increases stratosphere
the lowest layer of the atmosphere, in which temperature decreases at a constant rate as altitude increases troposphere
a layer (of gas) in the atmosphere at an altitude of 15 to 40 km in which ozone absorbs ultraviolet solar radiation ozone layer
the warming of the surface and the lower atmosphere of Earth that occurs when water vapor, carbon dioxide, and other gases absorb and reradiate thermal energy greenhouse effect
a measure of how hot (or how cold) something is; specifically, a measure of the average kinetic energy of the particles in an object temperature
the kinetic energy of a substance’s atoms thermal energy
an increase of the size of a substance in response to the increase in the temperature of the substance thermal expansion
the energy transferred between objects that are at different temperatures heat
the movement of matter due to the differences in density; the transfer of energy due to the movement of matter convection
the movement of air caused by differences in air pressure wind
the curving of the path of a moving object from an otherwise straight path due to Earth’s rotation Coriolis effect
the movement of air over Earth’s surface in patterns that are world wide global wind
a narrow band of strong winds that blows in the upper atmosphere jet stream
the movement of air over short distances; occurs in specific areas as a result of certain geographical features local wind
