Layers of the Atmosphere
Which layer of the atmosphere do planes fly in and why?
Stratosphere, because its easier to fly above the weather that is happening in the Troposphere.
The two most prevalent gases in the atmosphere are?
Nitrogen and Oxygen
How do we classify Air Masses?
By their temperature and their humidity
What does a warm front symbol look like?
It is a curved line with half circles on it.
Lots of rain year round and a steady high temp.
Which layer of the atmosphere is the has the greatest temperature drop?
Mesosphere
What is responsible for providing the Earth with energy?
The Sun
What type of front moves forward on a warm air mass and rapidly pushes the warm air up into the atmosphere? This sometimes leads to thunderstorms and the formation of cumulonimbus clouds.
Cold Front
How is climate different from weather?
Climate is over a long period of time and weather is a a snapshot of a short time period.
What causes Acid Rain?
Acid rain forms when gasses ejected by human activity lower the pH of water vapor
Which layer of the atmosphere contains the OZONE layer?
Stratosphere
The energy process that heats the majority of the atmosphere which involves hot air rising and cold air sinking is called
Convection
What kind of weather is most common along frontal boundaries (cold and warm fronts)?
Rain clouds
Which storm most likely develops as air masses interact with the warm water in the northwest Pacific Ocean?
A hurricane
Which is least likely to cause changes in global climate?
A tidal wave or a volcanic eruption?
A tidal Wave does not impact climate.
The ozone layer can be destroyed. What causes this and how is that bad for humans?
CFCs: Increased radiation due to less being absorbed by the ozone layer.
As Altitude increases what happens to the density?
It decreases
Which of the following weather events will most likely lead to clear and sunny skies?
Increase in Air Pressure
A weather satellite can take a picture of a hurricane from space and send it to Earth in seconds. How would the people of Hawaii benefit by having a picture of a hurricane so quickly?
People can be warned about a hurricane coming
What is something the average person can do to potentially reduce global climate change?
List the layers in order from the ground up and give 2 defining characteristics of each layer.
Troposphere- Weather occurs here, greatest air mass, greatest density, temp decreases
Stratosphere- where planes fly, ozone layer, temperature increases
Mesosphere- coldest layer, where meteors burn up, some satellites
Thermosphere- Greatest temp change, where satellites are located, contains the ionosphere,
Exosphere- outer space
As the Air Pressure Increases what happens to the Air Density?
It also Increases.
When a warm air mass and a cold air mass come together at a front what direction will they move?
The warm air will go up and the cold will go down.
If you see the barometric pressure dropping and the temperature is below freezing, what is probably going to happen?
A snowstorm.
Which of the following is most likely to increase the ocean temperature and rainfall on the western side of South America?
El Nino
