What is the elevation of Antarctica?
Due to this ice cover, Antarctica has the highest average surface elevation of all the continents at around 2000m above sea level (for comparison, the highest peak in the British Isles, Ben Nevis in Scotland, is 1343m); yet in many places the ice surface is much higher than this.
Who was the first Arctic explorer?
1900s. Americans Robert Peary and Matthew Henson, along with several Inuits, were the first people to finally reach the North Pole. They arrived on April 6, 1909, by traversing across the sea ice on dog sleds.
