Q50 (IAS/1998) Geography › Maps & Locations › World physical geography Answer Verified

Match rivers labelled A, B, C and D on the given map with their names given in the list and select the correct answer using the codes given below the list: List : 1. St. Lawrence 2. Orinoco 3. Mackenzie 4. Amazon 5. Yukon

Result
Your answer: —  Â·  Correct: B
Explanation

Option 2 is correct: A is the Yukon, B the Mackenzie, C the St. Lawrence and D the Orinoco. The Mackenzie is Canada’s major northward-draining river system into the Arctic, identifying river B in northwestern Canada. River C is the St. Lawrence estuary that links the Great Lakes with the Gulf of St. Lawrence and provides deep-water navigation to Montreal, matching the eastern North American label [1]. River A’s course from Yukon Territory through Alaska to the Bering Sea identifies it as the Yukon, and river D’s location in northern South America draining northward corresponds to the Orinoco. These basin locations and outlets uniquely fit the A–D assignments in option 2.
