Question

Into which ocean do the river lena and yenisey flow explain the reason for the direction of their flow​

Answer 1

Answer:

Since the three great Siberian rivers, Ob River, Yenisei River and Lena River all flow into the Arctic Ocean, the problem was to find parts or branches of these rivers that flow approximately east-west and find short portages between them. Since Siberia is relatively flat, portages were usually short.
