Greetings and welcome to the Thinking Spatially podcast series, the Thinking Spatially podcast series, where we think spatially across space, place, time, scale, and disciplines.
Joseph Kerski here, geographer, your host.
This year, each month, we will focus on a different set of five themes, place, space,
thought leader, tool, event, and geographic oddity.
So each episode will feature a place, a thought leader, a tool, an event, and a geographic oddity.
Thanks for joining me!
This episode's place will be the lowest points on land and sea.
Earth is covered by about 29% land and 71% ocean.
The average elevation of the land is 800 meters, or
2,624 feet.
Think about your own location.
Are you higher or lower than the average elevation of the land?
800 meters or 2,624 feet?
The average ocean depth is 3,700 meters or 12,139 feet deep.
Hmm.
The average height or depth for the whole Earth then, according to one calculation, is yielding
2,395 meters below sea level or minus 7,857 feet.
So for the whole Earth, the average is actually below sea level since there is so much ocean.
Interesting.
But perhaps even more interesting than these averages is the amount of variability in the Earth's elevations.
