What are the two largest rivers in Antarctica?

Answer 1

Antarctica is not known for its rivers, since 98% of the continent is covered with an ice sheet.

Seasonal, glacial melt-water run off does occur, and for example, the Onyx River flows about 32 miles during the 24/7 summer sun.

Answer 2

There are no rivers in Antarctica. Because Antarctica is a "polar" region, there is no precipitation, it has no lakes or rivers and is in fact the driest continent. Average temperatures in the Antarctic interior get down to -70 degrees Celsius during the winter months and -35 degrees Celsius in the warmer months. The coastal temperatures are much warmer with a range of -15 to -32 Celsius in Winter and -5 to +5 Celsius in Summer. The interior of Antarctica is considered the world's driest desert because the extreme cold freezes water vapour out of the air. Annual snowfall on the polar plateau is equivalent to less than 5 cm of rain. Antarctica has some of the strongest winds on earth, with some winds reaching 320 kph.
