    Height and temperature near the equator

    PlaceWhat the card says
    Guayaquil, Ecuadorclose to the equator and close to sea level; hot and humid
    Quito, Ecuadoralso close to the equator, but about 2,800 m above sea level; cool all year
    La Paz, Boliviain the tropics, about 3,600 m above sea level; people wear warm coats
    Peaks near the equatorsome tall peaks in the Andes near the equator are snow-covered all year

    Model rule: air is about 6.5°C cooler for every 1,000 m of height.

  2. Quito and Guayaquil both lie close to the equator, yet Quito is cool and Guayaquil is hot (card C). What best explains the difference, Ari asks?

    • Quito lies much farther from the equator than Guayaquil does, so it is cooler
    • Guayaquil is higher up the mountains, where the sun is closer to it
    • Quito has more rain than Guayaquil, which lowers the temperature through the year
    • Quito is about 2,800 m high, and air is cooler at greater height

  3. A balloon (made up) rises from a beach where the air is 30°C. Using card C's rule, about how warm is the air when it reaches 3,000 m, Bo asks?

    • About 28°C
    • About 49.5°C
    • About 10.5°C
    • About 23.5°C

  4. La Paz is in the tropics, yet people there wear warm coats (card C). What is the reason, Esme asks?

    • Towns in the tropics are cold, and La Paz is just like the rest
    • La Paz sits about 3,600 m high, where the air is much cooler
    • La Paz lies far from the equator, near the poles, so it is cold
    • La Paz is on the coast, where cold sea winds blow across the town

  5. Quito and Guayaquil share a latitude but not a temperature. What does that show about using latitude alone, Jun asks?

    • Height also changes temperature, so latitude alone cannot predict it
    • Latitude has no effect on temperature, so Quito's coolness is a puzzle
    • Cities near the equator are cold, so Guayaquil's heat is a puzzle
    • Temperature depends on the size of the city, not on its height

  6. A coastal town has air of 28°C (made up). A village on the same mountain, 2,000 m higher, is about how warm using card C's rule, Kira asks?

    • About 21.5°C
    • About 41°C
    • About 1.5°C
    • About 15°C

  7. Some tall peaks near the equator stay snow-covered all year (card C). Which chain explains it, Luz asks?

    • Snow is carried there from the poles by the wind
    • Height cools the air about 6.5°C per 1,000 m, so high peaks stay cold
    • Heat from the equator melts snow in winter, which then falls back as snow in summer
    • The equator is cold, so peaks there are cold at each height

  8. The Panama Canal

    TopicWhat the card says
    What it isan 82 km waterway built by people across the narrow land of Panama
    What it joinsthe Atlantic Ocean (Caribbean side) and the Pacific Ocean
    Lockssteps of water that lift ships about 26 m up to Gatun Lake and lower them again
    Before the canalships sailed around the southern tip of South America to pass between the oceans

    A lock is a chamber with gates; water is let in or out to raise or lower a ship.

  9. Suppose a trip around South America's southern tip is 20,000 km (made up) and the canal route is 12,000 km. How much shorter is the canal route, Pia asks?

    • 32,000 km shorter
    • 800 km shorter
    • 12,000 km shorter
    • 8,000 km shorter

  10. Ren writes three sentences about the canal. Which one does card D support?

    • People built the 82 km canal to join the Atlantic and Pacific
    • The canal joins the Pacific to the Caribbean Sea and nothing else
    • The canal is 82 m long, with locks that lift ships 26 km
    • Rivers formed the canal on their own over many thousands of years

  11. Put the chain in order for how the canal helped ships, using card D. Which is right, Tala asks?

    • Trips became shorter, so people built the canal, and then ships stopped sailing around
    • Ships sail around South America, so the canal gets longer, and trips are shorter
    • The locks made the two oceans join, so trips became shorter for ships
    • People built the canal, so ships skip the southern tip and trips are shorter

  12. Zee's note says, "The Panama Canal joins the Gulf of Mexico and the Caribbean Sea." Which fix uses card D?

    • It joins the Gulf of Mexico and the Pacific Ocean across Panama
    • It joins the Amazon River and the Pacific Ocean across the Andes
    • It joins the Atlantic Ocean (Caribbean side) and the Pacific Ocean
    • It joins the Atlantic Ocean and the Indian Ocean through the isthmus
