Four landscapes of East and Southeast Asia
Place Landscape Weather Mongolia's steppe and the Gobi wide, dry grassland and desert on a high plateau, far from any sea cold winters, warm summers, little rain Tibetan Plateau, western China the largest high plateau on Earth, about 4,500 m above sea level on average cold all year, thin air, dry Mekong Delta, Vietnam flat land at the river's mouth, close to sea level warm all year, with a wet season and a dry season Honshu, Japan an island where mountains cover most of the land; flat plains lie mostly along the coast cool winters, warm and humid summers Model rule: air is about 6.5°C cooler for every 1,000 m of height.
Herds graze on Mongolia's steppe far more than crops are grown there. Which fact on card A best explains that, Ari asks?
- Wide, dry grassland with little rain suits grass better than crops
- Its winters are warm, so herd animals can stay outdoors the whole year
- It is flat land close to sea level, which is good for grazing animals
- Thin air at 4,500 m keeps crops from growing there, but not the grass
The Tibetan Plateau averages about 4,500 m high (card A). Using the model rule, about how much cooler is the air there than at sea level, Bo asks?
- About 6.5°C cooler
- About 29°C cooler
- About 45°C cooler
- About 3°C cooler
Rice is grown in flooded fields. Which pair of facts on card A makes the Mekong Delta a good place for it, Esme asks?
- Flat land near sea level, and a warm climate with a wet season
- Flat land, but a dry climate with very little rain through the year
- Mountains with steep slopes, and cool, dry summers
- Flat land, but a cold climate with snow most of the year
Suppose a summer day on Honshu's coast is 28°C (made up). Using card A's rule, about what is the air temperature on a mountain 2,000 m above it, Kira asks?
- About 21.5°C
- About 15°C
- About 41°C
- About 1.5°C
Luz's note says, "All of Honshu is flat farmland." Which fix is supported by card A?
- Honshu is an island, so it has no flat land anywhere on its coasts
- Honshu is mostly flat, except for a few low hills in the far north
- Mountains cover most of Honshu; flat land lies along the coast
- Honshu is a dry desert, so there is very little farmland on it
Where three rivers start and end
River Where it starts Where it ends Yangtze the Tanggula Mountains, high on the Tibetan Plateau in the west the East China Sea, at sea level in the east Mekong highlands of the Tibetan Plateau in the northwest the South China Sea, through a delta in the south of Vietnam Yellow River the Bayan Har Mountains, high in the west the Bohai Sea, at sea level in the east Water flows downhill, from higher land toward lower land. A river that slows near the sea drops the silt it carried. A delta is low land built from that silt where a river meets the sea.
Card B shows the Yangtze starts high in the west and ends at sea level in the east. Which way does it flow overall, Milo asks?
- Toward the east, from the high west to the sea
- Toward the south, because rivers flow down the page of a map
- Toward the north, because it starts in the Tanggula Mountains
- Toward the west, from the sea up into the mountains
The Mekong starts in the northwest highlands and ends in the south of Vietnam (card B). Which way does it flow overall, Noah asks?
- Toward the south, from the northwest highlands to the delta
- Toward the east, because rivers end in the east
- Toward the west, because the Yangtze and Yellow River flow east
- Toward the north, from the delta up into the highlands
Pia stands at the start of the Yellow River and at its end (card B). Which statement is true about the land height at the two places?
- The start is higher than the end, since the river runs down to the sea
- The start is lower, since mountains are near the sea
- Both are at the same height, since a river stays level along its length
- The end is higher than the start, since the river climbs toward the sea
Card B says the Mekong flows through a delta. Tala asks what a delta is.
- The high mountains where a river starts
- A waterfall where a river drops from a plateau
- A narrow sea passage between two bodies of land
- Low land built where a river meets the sea
The Mekong Delta is flat land at the river's mouth (cards A and B). What best explains how it formed, Zee asks?
- The river drops the silt it carried where it meets the sea
- A volcano erupted there long ago and spread ash over the plain
- The sea level fell, and the old sea floor became dry farmland
- Glaciers carved the land flat, and the river followed them
