Atmosphere Layers
Name 1 layer of the atmosphere
What is Troposphere?
Describe Troposphere
Earth's weather
What is a Front?
Boundary between two different air masses
What causes wind on earth?
Wind is caused by changes in air pressure due to unequal heating
Explain how the atmosphere plays an important role in transferring thermal energy to the earth (3 ways)
Radiation
Conduction
Convection
What is the 2nd layer of the atmosphere?
What is stratosphere?
Describe Stratosphere
Ozone layers absorb ultra violet radiation
Name one front and describe the type of weather it brings
Cold Front- cold air mass runs into warm air mass and produces thunderstorms
What is sea breeze?
During the day when land heats up faster than water
What is radiation?
Energy from the sun warms earths atmosphere
What is the third layer of atmosphere?
What is mesosphere?
Describe Mesophere
Protects earth from meteors
Name a sencond front and describe the type of weather it brings
Warm front-warm mass mixes with cold mass and produces precipitation and fog
What is land breeze
During the night when land cools off faster than the water
What is conduction?
What is the 4th layer of atmosphere?
What is thermosphere?
Describe Thermoshere
Hottest layer, very dry
Describe the 3rd front
Stationary- cold and warm meet and causes clouds and light rain
List 4 types of technology used to predict weather
1. Satellites
2. Weather Balloons
3. Weather Stations
4. Computer Forecast
What is convection?
Circulation of liquids or gas
Define Atmospheric Pressure
measure of force that air molecules push on a surface and it decreases as altitude increases
Explain the composition of the atmosphere?
79% nitrogen
21% oxygen
Name and describe a 4th front
Occluded- fast moving cold mixes with slow moving warm, causes severe storms
Define Air Mass
Large body of air that has similar temperatures and moisture throughout
