Mod 3 Flashcards
Air pressure:
Air pressure: the force exerted onto a surface by the weight of the air
Coriolis effect
Coriolis effect: process of Earth’s rotation causing winds to curve
Electromagnetic waves:
Electromagnetic waves: a form of energy that travels through space
Global winds:
Global winds: winds that blow steadily from specific directions over long distances
Greenhouse effect
Greenhouse effect: process of trapping the sun’s heat in a planet’s lower atmosphere by gases like carbon dioxide, methane, and water vapor
Infrared radiation:
Infrared radiation: invisible form of energy that can be felt as heat
Jet stream:
Jet stream: narrow bands of very strong, mostly westerly air currents encircling the globe several miles above Earth’s surface
Latitude
Latitude: distance from the equator, measured in degrees
Specific heat:
Specific heat: the heat energy required to raise the temperature of one gram of a substance by one degree Celsius
Ultraviolet radiation:
Ultraviolet radiation: invisible form of radiation that can damage cells
Visible light:
Visible light: electromagnetic waves that are able to be seen by human eyes
Wind:
Wind: the movement of air from an area of higher pressure to an area of lower pressure
Climate
Climate: average weather patterns in an area, usually taken over a 30-year period
Meteorologist
Meteorologist: a scientist who studies the atmosphere and its effects on weather, climate, and the environment
Weather
Weather: current conditions in the atmosphere, including temperature, rain, wind speed, wind direction, humidity, air pressure, and clouds
Air mass:
Air mass: a huge body of air in the lower atmosphere that has similar temperature, humidity, and air pressure at any given height
Clouds
Clouds: a visible mass of condensed water vapor, floating above the ground in the atmosphere
Front
Front: the boundary where masses of different temperature and humidity collide
