Question 1

True or false: The Murray River is the only river in the world that flows through a desert.

Accepted Answer

False. Several rivers cross deserts, like the Nile and Colorado. The Murray flows through semi-arid areas, but not a true desert.

Question 2

True or false: The Darling River is actually longer than the Murray River, but carries less water.

Accepted Answer

True. The Darling stretches about 2,740 km vs. Murray’s 2,508 km, yet its flow is highly variable and often minimal due to arid conditions.

Question 3

True or false: More than 90% of Australia’s irrigated crops are grown in the Murray-Darling Basin.

Accepted Answer

False. The Murray–Darling Basin accounts for around 70% of Australia's irrigated agricultural land, not over 90%. It is a major region but not that dominant.

Question 4

True or false: The Murray-Darling Basin covers an area larger than France and Spain combined.

Accepted Answer

True. At over 1 million square kilometers, the basin spans about 14% of Australia’s landmass, dwarfing many European countries.

Question 5

True or false: Platypuses thrive in the urbanized sections of the Murray River near major cities.

Accepted Answer

False. Platypuses are sensitive to pollution and habitat disturbance. They rarely inhabit heavily urbanized stretches, preferring cleaner tributaries.

Question 6

True or false: The Murray River once flowed into the ocean, but now ends at a man-made lake.

Accepted Answer

False. The Murray River still reaches the Southern Ocean via natural Lake Alexandrina. Barrages regulate flow and prevent saltwater intrusion, but the river does not end at a man-made lake.

Question 7

True or false: The Murray-Darling River system is home to the world's largest freshwater crayfish species.

Accepted Answer

False. The world's largest freshwater crayfish is the Tasmanian giant freshwater crayfish (Astacopsis gouldi), found in Tasmania, not in the Murray-Darling basin. The Murray crayfish is large but not the largest.

Question 8

True or false: The Murray-Darling system was formed by a massive meteor impact millions of years ago.

Accepted Answer

False. The basin is a result of tectonic uplift and erosion over 60 million years, not a meteor. No impact crater exists in the region.
