Grade 9 Science Worksheet

Circle the best answer.

1. 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.

2. 1.

   Using the table, which city is on the coast, by Bo's reading?

   • Both, since their ranges match
   • City B, with the larger yearly range
   • City A, with the smaller yearly range
   • Neither, since range shows latitude
3. 2.

   Using the table, what is City B's yearly temperature range, by Esme's math?

   • 22 °C
   • 10 °C
   • 32 °C
   • −32 °C
4. 3.

   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)?

   • B, dry
   • A, tropical
   • H, highland
   • E, polar
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?

   • 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?

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

7. 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.

   Two coastal towns share a latitude; one faces a warm current and one a cold current (model). Which has milder winters, by Noah's reading?

   • The town by the cold current
   • They match, since latitude decides
   • The town by the warm current
   • Neither, since currents don't affect air
9. 7.

   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 ocean reflects the heat away
   • The ocean stores heat in a deep layer, damping temperature swings
   • Land stores more heat, so coasts swing more
   • The light depth matters just for fish
10. 8.

    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 72 to 77 °F
    • About 82 to 87 °F
    • About 15 to 20 °F
    • About 107 to 112 °F
11. 9.

    Climate graph for two cities. Why are many dry (B) climates near 20° to 35° latitude, by Tala's reading (NOAA)?

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

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