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.

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

   • Llamas and alpacas trample the crops, so few crops can be grown
   • The air is hot at that height, so crops dry out before harvest time
   • Cold air at that height leaves few crops, but animals can graze
   • The mountain turns into a dry desert up there, so crops fail
3. 2.

   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 13°C cooler
   • About 0.65°C cooler
   • About 2°C cooler
   • About 6.5°C cooler
4. 3.

   A family moves its farm from 800 m up to 2,600 m. What change in crops does card E suggest, Jun asks?

   • From bananas and sugar cane to potatoes, wheat and corn
   • From potatoes to bananas, since cooler air favors bananas
   • From coffee to llamas, since 2,600 m is above 3,500 m
   • No change, since crops do not depend on height
5. 4.

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

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

6. 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.

7. 5.

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

   • 43°C
   • 1.7°C
   • 23.5°C
   • 17°C
8. 6.

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

   • 3,000 m
   • 10,500 m
   • 19,500 m
   • 6,500 m
9. 7.

   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, cool land, so potatoes
   • About 20°C, mild land, so coffee
10. 8.

    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 22.8°C cooler
    • About 19.5°C cooler
    • About 1.95°C cooler
    • About 6.5°C cooler
11. 9.

    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 30,000 m, far above the top
    • About 6,500 m, well above the top
    • About 460 m, on the lower slope
    • About 4,600 m, above the top
12. 10.

    Zee says, "The top of the model mountain (4,000 m) would have snow." Using card F, is that supported?

    • Not by the model: about 4°C at the top is cold but above freezing
    • Yes, because 4°C is below freezing, so snow would settle there
    • Yes, because the top is above 3,500 m, where card E says few crops grow
    • No, because the base is 30°C, so the whole mountain is warm
