What sets a region's climate

Grade 9 Science Worksheet

Circle the best answer.

1. 1.

   A, on a coast, 10 °C, 20 °C; B, far inland, −5 °C, 27 °C. Using the table, which city is on the coast, by Bo's reading?

   • City A, with the smaller yearly range
   • City B, with the larger yearly range
   • Both, since their ranges match
   • Neither, since range shows latitude
2. 2.

   Climate graph for two cities. City C is near 5° latitude and is warm and wet in every month (model data). Which Köppen group fits, by Jun's reading (NOAA)?

   • H, highland
   • E, polar
   • A, tropical
   • B, dry
4. 3.

   A road climbs 6,000 feet from an 80 °F valley. Using NWS's normal lapse rate, about what temperature is it at the top, by Kira's math?

   • About 74 °F
   • About 101 °F
   • About 59 °F
   • About 76.5 °F
5. 4.

   NWS: the dry lapse rate is 5.5 °F per 1,000 feet. Dry air sinking 4,000 feet down the leeward side warms by how much, by Luz's math?

   Use the picture in question 3.

   • It cools by about 22 °F
   • About 5.5 °F
   • About 14 °F
   • About 22 °F
6. 5.

   Why does air sinking down the leeward side of a range stay dry, by Milo's reading?

   • It cools as it sinks
   • It lost its moisture rising over the windward side and warms as it sinks
   • The windward side is the dry one
   • It picks up rain as it sinks

7. Read this first

   Table, Two cities at the same latitude (model data), with columns City, January, July

   A, on a coast, 10 °C, 20 °C; B, far inland, −5 °C, 27 °C.

8. 6.

   NOAA: in clear tropical water light reaches 150 to 200 m, but on land it heats the top few inches. How does that shape coastal climate, by Pia's reading?

   • The light depth matters just for fish
   • Land stores more heat, so coasts swing more
   • The ocean reflects the heat away
   • The ocean stores heat in a deep layer, damping temperature swings
9. 7.

   NOAA: after a sea breeze front passes, air can cool 15 to 20 °F. If it was 92 °F before, what range follows, by Ren's math?

   • About 107 to 112 °F
   • About 15 to 20 °F
   • About 72 to 77 °F
   • About 82 to 87 °F

10. Use this

    Climate graph for two cities.

11. 8.

    Why are many dry (B) climates near 20° to 35° latitude, by Tala's reading (NOAA)?

    • They are farther from the Sun
    • Mountains block the wind there
    • Rising air there brings rain
    • Sinking air in the high-pressure belt near 30° brings dry weather
12. 9.

    NOAA: in polar (E) climates the warmest month averages under 10 °C. One city's warmest month averages 8 °C, another's 18 °C (model). Which is polar, by Zee's reading?

    • Neither city
    • The city with an 18 °C warmest month
    • The city with an 8 °C warmest month
    • Both cities
13. 10.

    A mountain with temperatures dropping up its side. A model city lies at 1° latitude but 2,800 m up, with mild temperatures all year. Which Köppen group fits, by Ari's reading (NOAA)?

    • H, highland, set by elevation
    • A, tropical, since it is near the equator
    • B, dry
    • E, polar
