This river starts on the Tibetan Plateau, runs through Laos and Cambodia, and builds a huge rice-growing delta in southern Vietnam. Name the river.

This river rises in northern Myanmar, flows south past Mandalay, and spreads into a broad delta before reaching the Andaman Sea. Name the river.

This river is formed by the Ping and Nan rivers, passes through Bangkok, and builds a delta on the Gulf of Thailand. Name the river.

This river begins in Yunnan, crosses northern Vietnam past Hanoi, and builds a densely farmed delta on the Gulf of Tonkin. Name the river.

This Borneo river drains East Kalimantan, flows east, and ends in a large delta on the Makassar Strait. Name the river.

This river crosses West Kalimantan on Borneo and reaches the sea near Pontianak on the island's western coast. Name the river.

This river drains the highlands of Sarawak and reaches a delta on northwest Borneo, making it Malaysia's longest river. Name the river.

This river flows from central Borneo south toward Banjarmasin and enters the Java Sea through a delta and estuary. Name the river.

This river flows through Palembang in southern Sumatra and reaches a delta along the Bangka Strait. Name the river.

This East Java river loops through volcanic uplands and splits into distributaries near Surabaya and Sidoarjo. Name the river.

Indonesia and the Philippines sit on a belt where oceanic plates dive beneath nearby plates, producing many active volcanoes. Name this belt.

A deep ocean trench parallels Sumatra and Java, with volcanoes on the islands inland from it. What plate process creates this pattern?

The Philippines has volcanic arcs and frequent earthquakes because the Philippine Sea Plate and nearby plates meet there. Classify the boundary.

An island arc curves along a trench from Sumatra toward the Lesser Sundas. Why do volcanic islands line up in an arc there?

Mainland Thailand and Cambodia have far fewer active volcanoes than Indonesia and the Philippines. What physical setting best explains this contrast?

Deep trenches lie beside Luzon and Mindanao, with volcanoes on the islands just inland. What hazard pattern should communities expect?

At a subduction zone, water from the descending slab helps mantle rock melt. What landform commonly forms above it in island Southeast Asia?

The Sunda Trench marks where one plate dives below another off Sumatra. In 2004, a huge earthquake there set off what deadly hazard across the Indian Ocean?

Singapore stays near 80°F all year and receives heavy rain in every month, with no real dry season. Identify the climate zone.

Bangkok is hot year-round but has a wet summer monsoon and a dry winter. Identify the best climate classification.

Yangon is hot all year, gets very heavy summer monsoon rain, and has only a short dry winter. Identify the climate classification.

Bagan in central Myanmar is hot but much drier than the coast because mountains block monsoon rain; grass and dry forest dominate. Classify it.

Hanoi has warm to hot rainy summers and noticeably cooler winters than equatorial cities. Identify northern Vietnam's lowland climate zone.

A station in northern Laos is cooler than nearby lowlands because it sits high in rugged mountains, while monsoon rains still arrive. Classify it.

Eastern Indonesia, including Timor, has hot temperatures, a pronounced wet season, a long dry season, and grassland with scattered trees. Identify the climate.

Interior Borneo near the Equator is hot, humid, and rainy all year, supporting evergreen broadleaf forest. Identify the climate zone.

A coastal mountain slope in western Myanmar is warm all year, gets very heavy summer monsoon rain, and has a brief dry season. Classify it.

Java supports very dense wet-rice farming, while much of Borneo has leached rainforest soils. What best explains Java's advantage?

The Mekong and Chao Phraya deltas are major rice areas. What physical feature makes deltas especially useful for wet-rice farming?

Upland farmers in Laos often terrace fields, while delta farmers use broad flooded paddies. What terrain contrast explains this pattern?

Rainforest trees in Borneo and Sumatra can be valuable timber, but cleared forest soils often lose nutrients quickly. Why?

Tin mining developed on the Malay Peninsula where erosion moved cassiterite from granite hills into stream valleys. What process concentrated the ore?

Brunei and parts of Sumatra have oil and natural gas, especially in coastal and offshore areas. What setting is most associated with those resources?

Laos has more hydropower potential than the flat Mekong Delta because its rivers drop from highlands through steep valleys. What factor matters most?

Peat swamp areas in Indonesia and Malaysia are harder to farm than nearby volcanic uplands. What soil condition limits farming there?
