What is the most common gas in the atmosphere?
Nitrogen
100
What is the formular for density?
Mass divded by Volume
100
In which layer of the atmosphere do we live in?
Troposphere
100
How is heat mostly transfered in the atmosphere?
By Convection
100
What causes wind?
The unequal heating of Earth's surface
200
What are three examples of sources of air pollution?
fossil fuels, cars, factories, forest fires, soil erosion, dust storms
200
What are the two kinds of barometers?
Mercury and Aneroid
200
What are the second and the third layer of the atmosphere?
Stratosphere and Mesosphere
200
What are the three ways of heat transfer?
Radiation, Conduction, Convection
200
What are the aajor global wind belts?
the trade winds, the polar easterlies, and the prvailing westerlies
300
What can the burning of fossil fuels cause?
Smog and Acid Rain
300
When altitude increases, air pressure...
dereases
300
In which two layers is the termosphere divided?
Ionosphere and Exosphere
300
What has shorter wavelengths, orange or blue?
Blue
300
What blows away, from the horse latitudes?
Prevailing westerlies
400
How does the atmosphere support livng things?
It regulates the temperature on Earth and prevents the surface from ultraviolet radiation by the sun.
400
How does altitude affect density?
When altitude increases, density decreases.
400
Name all layers of the atmosphere in order from Earth's surface to space.
Troposphere, Stratosphere, Mesosphere, Thermosphere
400
How do you experience the greenhouse effect?
Greenhouse, Car heats up when standing in the sun more than the air around it
400
Where are the horse latitudes?
30 degrees north and south
500
List all gases in the atmosphere
Nitrogen, Oxygen, Argon, Carbon Dioxide, Neon, Helium, Methane, Krypton, Hydrogen
500
Why does the air pressure decrease as altitude increases?
Because less air is pushing down on you?
500
What special features does each layer have?
Troposphere- Weather Stratosphere- Ozone Mesosphere- protects Earth from meteroids Thermosphere- Auroras
500
Describe how heat is transfered by radiation, conduction, and convection within the atmosphere.
Radiation- from the Sun to Surface, from the Surface back into the atmosphere Conduction- from the surface to the air Convection- The air heats up at the grund, then rises and cools down until it sinks
500
What blows from the horse latitudes to the equator?
Trade Winds
