100
This weather front has blue arrows pointing in the direction of air movement.
What is a cold front?
100
This type of pressure is denoted as a "H" on a weather map and is associated with clear weather.
What is high pressure?
100
This is the instrument that measures temperature.
What is a thermometer?
100
Most severe weather is caused by this type of front.
What is a cold front?
100
Warm air rises and cools to form these floating objects through condensation of humidity.
What are clouds?
100
As air flows over bodies of warm water and picks up moisture, this effect occurs over land.
What is precipitation?
200
This weather front has red semi-circles that move in the direction of the circles.
What is a warm front?
200
This type of pressure is denoted as a "L" on a weather map and is associated with storms and hurricanes.
What is low pressure?
200
This weather instrument measures the direction the wind is flowing in.
What is the weather vane?
200
This is the direction that station model wind barbs point.
What is the direction that the wind is coming from?
200
This type of cloud is produced when strong cold fronts move through an area to produce powerful storms.
What are cumulonimbus clouds?
200
This is how the volcano Mt. Pinatubo caused climate change with sulfur dioxide and ash when it erupted.
What is the particles decreased solar radiation reaching the surface?
300

This weather front has alternating red semi-circles and blue triangles and does not move.
What is a stationary front?
300
Wind always flows from this pressure to the other pressure.
What is from high to low pressure?
300
These instruments measure the humidity in the air.
What are hygrometers or (sling) psychrometers?
300
Cold air and objects cause this effect, in which water vapor collects into droplets onto condensation nuclei.
What is condensation?
300
This type of cloud is associated with snow and long-lasting rain.
What are stratus?
300
Carbon dioxide has increased in the atmosphere due to this.
What is the increase in burning fossil fuels?
400
This weather front has purple triangles and semi-circles and three fronts involved.
What is an occluded front?
400
A low pressure system (hurricane) has left the equator. What happens when the system reaches the cooler waters of 60°N?
What is that it has lost most of its energy?
400
This instrument measures air, or atmospheric, pressure.
What is a barometer?
400
This process of rising warm air and sinking cold air is a major cause of weather.
What is "convection"?
400
Warm air must do these steps to form clouds.
What are rise, cool, and condense water vapor?
400
This is how carbon dioxide and atmospheric temperatures have recently changed, as shown in the graph.
What is an increase in both carbon dioxide levels and atmospheric temperatures?
500
These are lines of equal atmospheric pressure.
What are isobars?
500
On a station model, pressure must be converted from the provided number. Identify the converted pressures for 347 and 671.
What are 1034.7 and 967.1?
500
This is the instrument that measures wind speed.
What is an anemometer?
500
This effect produces rotation effects on large storms; the spin is different north and south of the Equator.
What is the Coriolis Effect?
500
These particles of ash or dust are required for water to condense into clouds.
What are "condensation nuclei"?
500
This is why the amount of oxygen has increased in Earth's atmosphere.
What are photosynthetic algae and plants?
