    Weather Unit Review

    1. What is the difference between weather and climate?

    ; Weather

    ; Climate

    2. Identify which of the following refer to climate and which refer to weather by writing “climate”

    or “weather” in the space to the left of the following statements:

    _______ In central Ontario, snowfall on December 25 occurs less than 50% of the time.

    _______ December 25, 1999, was warm and cloudy.

    _______ Hurricane Hortense struck the Nova Scotia mainland on September 15,1996.

     _______ Most hurricanes in Atlantic Canada occur in September or October.

3. Describe the three methods of how energy can be transferred:

    ; Radiation:

    ; Conduction:

    ; Convection:

4. For each statement below, write the method of energy transfer:

     Warm water near the equator moves north or south by ocean currents ___________________

     A metal spoon that is left in a pot of boiling water becomes warm ___________________

     Energy from the sun travels through space to reach the Earth's surface __________________

    5. What is a heat sink? ____________________________________________________________


    Give an example: ________________________

    6. What does heat capacity describe? _________________________________________________


    How does the heat capacity of water compare to land? ________________________

    7. The Earth's atmosphere is mostly made up of _______________________________ gas.

    8. Put the layers of the atmosphere in order, starting with the layer that is closest to the earth:

    _______ Stratosphere

    _______ Exosphere

    _______ Troposphere

    _______ Thermosphere

    _______ Mesosphere

    9. For each statement below, write in the name of the atmospheric layer each describes:

     Where most of our weather occurs _______________________

     Contains most of the ozone layer _______________________

     Contains ions, and is where the northern lights occur _______________________

     The coldest temperatures in the atmosphere _______________________

     Can be called "space" because there are very few particles _______________________

    1. The Earth's rotation causes a rotating effect in weather systems. This rotating effect is called the

    ______________________________ effect.

    ; in the Northern Hemisphere ocean currents rotate

    ; in the Southern Hemisphere ocean currents rotate

    ; the ocean current moving north along the East side of North America is the

    ; this current is (slow, fast) and (warm, cold)

    10. The Gulf Stream has the following effect on the summer climate of Newfoundland when

    compared to an inland location in Central Canada at the same latitude:

    a. it is colder with more precipitation.

    b. it is colder with less precipitation.

    c. it is warmer with more precipitation.

    d. it is warmer with less precipitation

    11. There are two main types of air currents that are responsible for the wind patterns across the

    world. These are the _________________________ and _________________________.

    12. The earth's rotation causes the movement of air masses and depending on your location from the

    equator, you will experience different wind patterns:

    a. From the equator to 30; latitude, the prevailing winds are _______________________

    b. From 30 ; latitude to 60 ; latitude, the prevailing winds are _______________________

    c. From 60 ; latitude to the north pole, the prevailing wind are _______________________

    13. What are jet streams? ___________________________________________________________


    14. Knowledge of the daily jet streams is useful to which profession? ________________________

    Explain why. __________________________________________________________________


    15. What are the two different types of clouds? Describe each different type.

    ; ____________________: _______________________________________________

    ; ____________________: _______________________________________________

16. What is the name of storm clouds? _______________________________

    How are these type of clouds recognizable? _________________________________________

    17. Clouds are also classified according to their height:

    ; low-level clouds: ___________________________

    ; middle-level clouds: ___________________________

    ; high- level clouds: ___________________________

18. Forecasting weather is not easy and a specific task. Regional forecasts may differ. Explain why

    this is the case.

    19. There are many different types of precipitation.

    a. What is precipitation?

    b. What causes the formation of the different types?

    20. Not all places receive the same amount of precipitation.

    a. In general, which cities receive more?

    b. Why is this the case? Explain.

21. Complete the following table to summarize how the various factors introduced in this chapter

    interact to produce a global weather model. Write your answers for a typical Northern

    Hemisphere winter day.

    Factor How It Affects Global Weather Patterns

    Solar Energy

    Cloud Cover

    Earth’s Rotation

    Jet Streams

    Prevailing Winds

    Ocean Currents

    Land Masses

    The Hydrosphere

    For each of the following questions determine whether the statement is true or false.

    1. Wind direction is reported as the direction from which the wind is blowing.

    2. Clouds associated with stormy weather are classified as nimbus clouds.

    3. Jet streams are fast moving ocean currents.

    4. The names of middle level clouds start with the prefix "alto".
