Atmosphere
What is the most abundant gas in the atmosphere?
Nitrogen
A large body of air that has nearly uniform temperature and humidity throughout
What is an air mass
The reason why there are different types of weather/wind in different seasons of the year
The tilted axis of Earth and position in its orbit around the sun ( Direct /Indirect Heat)
Deflection of the wind
Wind moving freely over Earth's surface has a tendency to curve away from its path of travel
What is the Coriolis Effect
The gradual increase in Earth's average temperature that scientists agree is caused by human behavior
What is climate change
The layer of atmosphere in which most weather occurs
What is the troposphere
A boundary where opposing air masses meet (fight)
What is a front
A low-pressure system is spinning counter-clockwise in the
What is the Northern Hemisphere
Type of local winds in the daytime where the breeze goes from the sea to the land
Sea Breezes
Polar Easterlies, Westerlies, Trade Winds, and Doldrums are all types of
Global Winds
Increasing altitude in the troposphere affects the air pressure by causing it to _________.
What is decrease
A front that lingers
What is a stationary front
Bad weather is produces by what type of air pressure system ?
Low Pressure System
Huge storms that originate in the tropics above warm ocean water
What is a hurricane
Warm air /water rises while cold air/water sinks.
Convection / Convection currents
Air flows from an area of high pressure to an area of low pressure, causing _______.
What is wind
Which type of front produces the most severe weather
Cold Fronts
Rain, sleet, snow, and hail occur when these droplets and ice crystals in clouds become too heavy and fall; this is an example of _____.
What is precipitation
Low altitude winds blowing at a different speed and direction that winds above may result in a violent rotating air column
What is a tornado
Which type of air masses would have weather conditions that would be dry and cold
Continental Polar
Wind is affected by these 3 factors
Direction, speed, heating of the earth
A cold front takes over a warm front, and catches up with another cold front
What is an occluded front
Fast moving air that flows from West to East and has colder air north of it and warmer air south of it.
Jet Stream
What stages of the water cycle use heating processes.
Evaporation, Transpiration & Sublimation
The current state of the atmosphere versus the average weather of an area over a long period of time is the difference between _______ and _______.
What is the difference between weather and climate
