What is/are the main difference(s) between the Ganges and Yukon deltas?
ANSWER Similar to the Yukon Delta is the Lena Delta in eastern Siberia formed where the Lena River empties into the Laptav Sea north of the Arctic Circle. Another rather exotic delta is that of the Parana River between Uraguay and Argentina: Rivers can produce land “deltas”, widespread deposits that build up as streams carrying heavy loads down steep gradients then encounter flatlands, with low gradients that cause the load to drop and spread out as the system meanders. These are called alluvial fans. One of the biggest in the world occurs in the Badain Jaran desert of east Asia, where the Ruo Shui River drains north from the Nan Shan mountains: Rivaling that in size (and not too far away) is this fan in the southern Taklimakan Desert in Sinkiang Province, western China.
