Air and Atmosphere
In what layer of the atmosphere does most weather occur?
What is the troposphere
the tool used to measure temperature
What is a thermometer
the horizontal movement of air from an area of high pressure to an area of lower pressure
What is wind
a huge body of air that has similar temperature, humidity, and air pressure throughout it
What is air mass
There is a tornado coming! Where is the safest place to be?
What is the basement or away from a window.
Warm air is less __________ than colder air. That is why it rises.
What is dense
Which type of heat transfer takes place by touch? (For example, holding a warm cup of hot chocolate to warm your hands)
What is conduction
how winds are caused
What is differences in air pressure; the uneven heating of Earth by the sun
a warm, humid air mass that forms over oceans near the tropics
What is maritime tropical air mass
What is the energy source for hurricanes?
What is warm water
As altitude in the atmosphere increases, air pressure _______________________.
What is a decreases
the direct transfer of energy by electromagnetic waves (for example, the sun warming you when you are outside)
What is radiation
A local breeze that occurs during the day and causes wind to move from the water on to the land is called a...
What is a sea breeze
cool, humid air masses that form over icy cold North pacific or North Atlantic oceans
What is maritime polar air mass
What two things are used to characterize air masses?
What are temperature and humidity
Air moves from areas of __________________ to areas of ______________________.
What is high pressure to low pressure
The process that helps to trap in radiation from the sun and help warm the Earth is called the...
What is Greenhouse Effect
The Earth's winds appear to curve due to what?
What is the Coriolis Effect
An air front that forms when cold, cool and warm air masses collide. The warm air mass becomes trapped and pushed up between the cooler air masses. Storms may form.
What is an occluded front
What type of severe weather usually happens before both a hurricane and tornado?
What is a thunderstorm
The Earth's atmosphere is made mostly of what 2 gases?
What are nitrogen and oxygen
The transfer of heat by the movement of a fluid; based on the densities of the substances.
What is convection
These Global Winds are found at the Equator.
What are the doldrums
A sudden thunderstorm comes blowing through quickly, and after it has passed, the weather outside is nice and sunny. What type of front probably passed through your area?
What is a cold front.
Yikes! I just saw lightning! 6 seconds later, I hear a giant clap of thunder. How far away did the lightning most likely strike?
What is 2 km
1km=3 seconds
