ANSWERS TO REVIEW QUESTIONS
CHAPTERS 1 THROUGH 6
A1-1. The metric (CGS centimeter-gram-second) system measures length, weight and
A1-3. A dyne is a measure of force.
A1-4. Sunspots are regions of strong localized magnetic fields and indicate relatively
cool areas in the photosphere.
A1-5. The Southern Hemisphere receives the greatest amount of incoming solar
radiation around December 22.
A1-6. Land and water surfaces absorb 51 percent of the earth's insolation.
A1-7. An air column over the poles is thinner than an air column over the equator.
A1-8. Pressure is the force per unit area.
A1-9. With a sea level pressure reading of 1000 MB, the approximate pressure at
18,000 ft will be 500 MB.
A1-10. Temperature change has the biggest effect on pressure change.
A1-11. Temperature is the measure of molecular motion.
A1-12. 20 degrees C converted to Fahrenheit is 68 degrees.
A1-13. The earth's meteorological atmospheric zones in ascending order are the
troposphere, tropopause, stratosphere, stratopause, mesosphere, mesopause,
thermosphere, and the exosphere.
A1-14. The four methods of heat transfer are conduction, advection, convection, and
A1-15. Advection is the horizontal transport of heat.
A1-16. The three states in which moisture in the atmosphere is found are solid, liquid and
A1-17. The primary sources of atmospheric moisture are the oceans.
A1-18. The difference between relative humidity and absolute humidity is that relative
humidity is the ratio (in percent) between the water vapor actually present and
the water vapor necessary for saturation at a given temperature.
humidity is the amount of water vapor present per unit volume of space.
A1-19. The mixing ratio is defined as the ratio of the mass of water vapor to the mass of
A1-20. The dew point is the temperature that the air must be cooled, at a constant
pressure and constant water vapor content, in order for saturation to occur.
