What is the outermost layer of the atmosphere?
Exosphere
100
What is the role of carbon dioxide and water vapor in the atmosphere?
Trap heat within the atmosphere
100
What do we often see in areas where air move between the land and the ocean, causing a dry and a wet season?
Monsoon effect
100
What is the transfer of heat by direct contact?
Conduction
200
Which layer of the earth's atmosphere includes almost all weather events?
Troposphere
200
What is the most abundant greenhouse gas?
Water vapor
200
What are the high-altitude winds that are concentrated in narrow, meandering bands of rapidly moving air?
Jet streams
200
What is the process in which the temperature of a gas rises as the gas is compressed with no heat lost?
Adiabatic heating
300
Where is the magnetotail?
Away from the sun. The solar wind pushes the magnetic field away from the sun and into magnetotails.

What does solar wind form in the atmosphere?
Arouras and the shape of the magnetosphere
300
Which circulating currents of air are found near the equator?
Convection cells
300
What are auroras?
Colorful areas characterized by some of the sun's charged particles entering the atmosphere
400
What is the difference between the temperature gradients of the troposphere and the stratosphere?
As you go higher in the troposphere, the temperature decreases. As you go higher in the stratosphere, the temperature increases.
400
What are the Van Allen belts?
Doughnut-shaped regions surrounding the earth and trapping particles from the solar wind
400
What is a foehn?
A warm, dry wind that travel down mountain slopes
400
What is insolation?
The solar energy that reaches the surface of the earth
500
Draw a diagram of the earth’s atmosphere that includes the following layers: Exosphere, Stratosphere, tropopause, troposphere, mesosphere, mesopause, thermopause, thermosphere, stratopause
500
What is the ozone layer?
Layer inside the stratosphere that protects the earth against UV radiation.
500
What are the two factors that cause the Coriolis effect?
Inertia
Objects on the earth's surface travel at different speeds depending on their distance from the earth's axis
500
Explain four factors that affect insolation.
Uses of energy - about 50% is reflected or absorbed by gases
Length of daytime - a longer exposure to sun means more energy
Latitude - when the sun's rays are at an angle, heat is dispersed more
Earth's distance from the sun - the earth is closer to the sun during the summer in the Southern hemisphere
