Which pressure system causes barometric pressure to decrease?
Low Pressure System
100
What are the 4 types of air masses?
Continental Polar; Continental Tropical; Maritime Polar; Maritime Tropical
100
What is the sun's energy called?
solar radiation
100
What are the 4 types of fronts we studied?
1. Cold Front 2. Warm Front 3. Stationary Front 4. Occluded Front
100
Does cold or warm air hold less water vapor and why?
Cold air because water molecules slow down enough to attach to tiny particles of dust or smoke.
200
Which pressure system brings cool, dry air with sunny skies and fair weather?
High Pressure System
200
Which type of air mass causes heat waves and droughts?
Continental Tropical
200
The sun is responsible for what aspects of weather?
1. Precipitation 2. Temperature 3. Wind
200
Draw the symbols for each of the four fronts.
See work
200
What is the difference between dew and frost?
dew is liquid water that condenses from the air and frost is ice that has condensed
300
What is a meteoroligist?
An scientist who studies weather
300
Where might a continental polar air mass form?
over Canada
300
How is the sun involved in precipitation?
It causes water to evaporate.
300
When a cold air mass and a warm air mass meet, how do the two types of air interact?
the warm air rises above the cold air; the more dense cold air sinks
300
What kind of weather can be predicted from cirrus clouds?
fair and pleasant weather
400
Which directions do winds blow in a low pressure system?
They blow in toward the low pressure system.
400
What kind of weather do maritime tropical air masses typically bring?
rain and thunderstorms
400
How does the sun influence temperature?
The sun's energy causes temperature of the air to rise.
400
What is a stationary front and what kind of weather does it bring?
It is when a cold air mass and warm air mass meet but do not move towards or away from each other. It brings days of precipitation.
400
What kind of weather can be predicts from nimbostratus clouds?
drizzle
500
What is the difference between weather and climate?
Weather is the daily conditions for a location and climate is the average conditions of a location over a long period of time.
500
What kind of air mass has cool and moist air?
maritime polar
500
How are the sun and wind related?
The sun heats the earth unevenly. The movement of air between warm and cold regions causes wind.
500
What kind of weather typically follows after a cold front passes?
cold, dry air moves in bringing clear skies and lower temperatures
500
Classify the type of cloud
Cumulonimbus (thunderstorm)
