Why did Robert falcon Scott die?

Answer 1

Scott and his team died on the return trip from the South Pole in Antarctica, where they had been attempting to be the first to reach the pole. (Norwegian team led by Amundsen's team arrived a month before Scott's.)

The Scott group ran out of food and oil on the way back to their base at Cape Evans, and were hampered from reaching supplies by bad weather closing in. Scott was the last member of the expedition to die only 11 miles from the One Ton Depot.

It is assumed that the cause would be a combination of vitamin deficiency, starvation, hypoglycemia and hypothermia
