1. Read this first

   Typical farming zones on a tropical mountain (rounded ranges)

   Zone	Height above sea level	What is grown
   Hot land	below about 1,000 m	bananas and sugar cane
   Mild land	about 1,000 to 2,000 m	coffee
   Cool land	about 2,000 to 3,500 m	potatoes, wheat and corn
   Cold, high land	above about 3,500 m	grazing llamas and alpacas; few crops

   Ranges are rounded and differ from place to place.

2. 1.

   A farm sits 1,600 m above sea level on a tropical mountain. Using card E, which crop fits, Ari asks?

   • Bananas, which fit hot land below about 1,000 m
   • Potatoes, which fit cool land at about 2,000 to 3,500 m
   • Coffee, which fits mild land at about 1,000 to 2,000 m
   • Llamas, which graze above about 3,500 m
3. 2.

   Few crops grow above about 3,500 m, and animals graze instead (card E). What best explains that, Bo asks?

   • The mountain turns into a dry desert up there, so crops fail
   • Cold air at that height leaves few crops, but animals can graze
   • The air is hot at that height, so crops dry out before harvest time
   • Llamas and alpacas trample the crops, so few crops can be grown
4. 3.

   On card E the mild zone tops out near 2,000 m and the hot zone near 1,000 m. Using the 6.5°C rule, how much cooler is the top of the mild zone, Esme asks?

   • About 2°C cooler
   • About 0.65°C cooler
   • About 13°C cooler
   • About 6.5°C cooler
5. 4.

   Kira writes a claim from card E. Which one is supported?

   • Different heights suit different crops, as the air cools with height
   • Coffee grows at the very bottom of the mountain, where it is hot
   • Crops depend on the name of the mountain, not on how high the farm sits
   • A crop grows well in each zone, since a mountain is just one place
6. 5.

   Luz's note says, "Potatoes grow best on the hot lowlands, below 1,000 m." Which fix uses card E?

   • Potatoes fit cool land, about 2,000 to 3,500 m above sea level
   • Potatoes fit cold, high land, above about 3,500 m
   • The note is right, since hot land grows each of the crops
   • Potatoes fit mild land, about 1,000 to 2,000 m above sea level

7. A model mountain (made up)

   Measure	Value
   Height of the mountain	4,000 m
   Air temperature at the base, at sea level	30°C
   Rule	air is 6.5°C cooler for every 1,000 m of height

   Made-up numbers for practice. Real mountains differ from the rule.

8. 6.

   On Milo's model mountain the base is 30°C. Using card F's rule, what is the air temperature at 2,000 m?

   • 23.5°C
   • 1.7°C
   • 43°C
   • 17°C
9. 7.

   On the model mountain (card F), at what height does the air reach 10.5°C, Noah asks?

   • 19,500 m
   • 10,500 m
   • 6,500 m
   • 3,000 m
10. 8.

    At 1,500 m on the model mountain (card F), Pia wants the air temperature and the crop from card E that fits. What are they?

    • About 23.5°C, mild land, so coffee
    • About 20°C, hot land, so bananas
    • About 20°C, mild land, so coffee
    • About 20°C, cool land, so potatoes
11. 9.

    A hiker climbs the model mountain (card F) from 500 m to 3,500 m. About how many degrees cooler is the air at the top of the climb, Ren asks?

    • About 6.5°C cooler
    • About 1.95°C cooler
    • About 19.5°C cooler
    • About 22.8°C cooler
12. 10.

    Suppose the base is 30°C. At what height on the model mountain (card F) does the air first fall to about 0°C, Tala asks?

    • About 460 m, on the lower slope
    • About 6,500 m, well above the top
    • About 4,600 m, above the top
    • About 30,000 m, far above the top
