Dec 21
When does the summer solstice occur in the northern hemisphere?
June 21-22
The tropopause is
The boundary between the troposphere and stratosphere
The heating of the lower layer of the atmosphere from radiation absorbed by certain heat-absorbing gases is called
Green house effect
Isotherms are lines that connect points of equal
Temperature
Which of the following best describes temperature variations
Variations are greater over land than over water
Earth receives energy from the sun through what method of heat transfer
Solar radiation
In general what is true about places at higher altitudes
They have cooler temperatures than places of lower altitudes
When does the autumnal equinox occur in the Southern Hemisphere
March 20-22
Two most important heat absorbing gases in the lower atmosphere are
Carbon dioxide water vapor
What causes heat or the transfer of energy from one object to another
Difference in temperature
All matter is composed of atoms or molecules that have energy of motion also known as
Kinetic energy
When do the suns rays strike latitude 23.5 s at and angle of 90 degrees
Dec 21 winter solstice
Which electromagnetic waves travel through space at a speed of
300,000 kilometers per sec
At night clouds act as a blanket by
Absorbing outgoing radiation
many clouds have a high albedo and therefore tend to
Reflect sunlight
Best describes the primary wave lengths of radiation emitted by earths surface
Longer than those emitted by sun
Which process involves mass movement within a substance
Convection
True or false on equinoxes days and nights are equal in length everywhere
True
Scattering
Associated with the weak light rays that travel in different directions
Based on figure 17-1 what is likely true of city a
It is located on a leeward coast
What is true about city b
Both a and b
Why are temperature ranges in the Southern Hemisphere generally smaller than those in the norton hemisphere
There is a greater percentage of water surface in the Southern Hemisphere
Most abundant gas in atmosphere
Nitrogen
