Weather Study Guide
The gas that makes up almost 78% of the atmosphere is?
Nitrogen
Air pressure is what at the Earth's surface?
Strongest
The transfer of thermal energy by the circulation of a liquid or gas is called ?
Convection
What are the differences in air pressure generally caused by?
Unequal heating of the Earth
Prevailing winds that blow from east to west found on both sides of the equator are?
Trade Winds
The layer of the atmosphere that has the highest temperatures is the ?
Thermosphere
When you fly from Virginia to California, the flight takes 5 hours. When you return to
Virginia, the flight takes only 4 1/2 hours. This is probably due to the?
Jet Stream
Warm air does what compared to cold air?
Rises
As altitude increases, air pressure does what?
Decreases
As altitude decreases, air pressure does what?
Increases
Use the weather
map to answer the
following
questions.
List at least two states that are having precipitation? How do you know?
(Ohio, Illinois, Indiana, Pennsylvania, West Virginia, Missouri) These are some of
the states that the Low is sitting over and precipitation is usually associated with a
warm front.
Know what type of weather front is over a certain state?
Example: A cold front is sitting over the state of Texas and the skies are clear.
Know what kind of weather will a state be having once the front arrives?
Example: Virginia will be experiencing some precipitation as the warm front arrives
with the low.
Know what kind of weather is the country (North of U.S.) having? How do you know?
Canada is experiencing clear skies with a high sitting over the area. No precipitation
can be seen around the high.
What is happening over the plain states? What kind of weather are they having?
A stationary front is sitting over the plain states and some light snow can be seen to
the west of the front.
What is arriving off the West Coast Line?
A low is arriving off the West Coast bringing with it some precipitation.
What kind of weather passed on the East Coast Line?
Precipitation will be passing soon off the East Coast associated with the Low warm
front.
The winds that have the most effect the United States?
Westerlies
Differences in air pressure usually cause?
Winds
The layer in the stratosphere that protects life on Earth by absorbing
harmful ultraviolet radiation?
Ozone
The layer of the atmosphere that is closest to the Earth is ?
Troposphere
The gradual warming in the average global temperatures of Earth over the past 100
years is referred to as ?
Global Warming
A gas form of water that exists in the atmosphere is called?
Vapor
The apparent curving of the path of winds due to the Earth's rotation is called the?
Coriolis Effect
Provide a good example of when the weather doesn’t match the climate. Give details!
Florida usually has mild temperatures during the winter. If a cold front arrives with
precipitation and the temperatures drop, Florida could get clobbered with a snow storm.
Give an example of conduction, convection, radiation. What do these words have to do
with weather?
Conduction = Requires Direct Contact
Convection = Found in Air or Water
Radiation = Warming by the sun
The Earth is heated by the sun’s radiation. Then the heat is absorbed by the Earth through
conduction. Finally, the heat is released back into the troposphere through convection
currents.
What is the difference between a tornado and a hurricane?
Hurricanes usually develop over water and can last several days. The season begins in
June and continues through November.
Tornadoes usually develop over land and last only a short period. The season begins in
March and last through August
Hurricanes and tornadoes both form in warm, damp air when winds blow into each other
from opposite directions.
Draw a picture of the globe and label all the different kinds of winds.
