Total questions: 20
Worksheet time: 10mins
What part of the atmosphere features convection cells, wind, clouds, and weather?
the thermosphere
the stratosphere
the mesosphere
the troposphere
What is the name of the effect whereby moving air and water currents bend to the right in the Northern hemisphere because of Earth's rotation?
Hadley
Coriolis
Cumulonimbus
Convection
Hadley, Ferrel, and polar are the names of
bears
feuding Kentucky families
atmospheric circulation cells
cloud types
Currents of circulating air or other fluid caused by differences in temperature
Jet streams
Trade winds
Coriolis
Convection
Air that is warmer than the air surrounding it
rises
sinks
stays where it is
Air that is cooler than the air surrounding it
rises
sinks (descends)
stays where it is
Rising air leads to ____ pressure at ground level
High
Low
Descending air leads to ____ pressure at ground level
High
Low
Regions of low pressure are
Stable with little air movement; air masses form here
Unstable, with air movement, changing conditions, and precipitation
Regions of high pressure are
Stable with little air movement; air masses form here
Unstable, with air movement, changing conditions, and precipitation
Fast-flowing currents of air high in the troposphere are
Hadley cells
Jet streams or "atmospheric jets"
Trade winds
Altostratus
The jet streams
All flow in the same direction, from west to east
Flow in different directions depending if they are north or south of the equator
Flow in different directions depending if they are above rising or falling air
All flow in the same direction, from east to west
Winds blow
From regions of high pressure to regions of low pressure
From regions of low pressure to regions of high pressure
In ways that are impossible to predict
Always from north to south
What is the effect of global circulation on temperatures around the Earth?
global atmospheric circulation does not affect temperature
global atmospheric circulation makes hot places hotter and cold places colder
global circulation moderates temperatures, warming the poles and cooling the equator
temperatures change in a random fashion
The trade winds are
The area close to the equator where rising air leaves ships stranded
Wind belts north and south of the equator, blowing from the northeast and southeast
Prevailing west winds in the mid latitudes
Extremely cold air blowing down from the poles
Westerlies are
People who traveled Westward in the pioneer days
People from the coastal states of California, Oregon, and Washington
Prevailing winds at the mid latitudes (the Ferrel cells)
Fast-moving currents of air high in the troposphere
What is the engine that drives atmospheric circulation?
Rotation of the Earth
Earth's magnetic field
Heating near the equator by direct sunlight
Currents in the oceans
Air masses stay in their source region for a long time. Most of them form
Near the tropical or polar highs, where high pressure makes the atmosphere stable
Near the equator where air is rising and the atmosphere is unstable
They can form anywhere on Earth
Near the polar front where air is rising and the atmosphere is unstable
Air masses take on the temperature and humidity of their
destination
wherever they are
upper atmosphere
source region
Air masses can be
A few feet across
a few miles across
a few dozen miles across
hundreds or over a thousand miles across
