# Geography/Wet equator / dry equator

Question
Age - 43 / Study level - independent / Country - USA / Language - English

Hello! Could you tell me how much of the earth's equatorial line is on land and how much is on the oceans. The only answer I could find in my own research is 78.7% ocean, some 7% higher than the global aveage. Could you be a secondary-source confirmation or correction to this? Thanks very much in advance for your time & help! -JMM

Hi, sorry this took a while, it is seemingness useless data? Why would you need to know this? My curiosity is stronger and after not finding any measurements or distances on the entire web, I have decided to survey this myself using Google-Maps. It will take a while as my time is limited. You can see the progress at http://goo.gl/maps/vfUMH

I used a calculation tool at http://www.movable-type.co.uk/scripts/latlong.html to calculate the distances between the coordinates at http://en.wikipedia.org/wiki/Equator where I have added the rough distances, each stage within one kilometer accuracy. This tool also show a map of the section.

Result: 7696km (19%) of land equator and 32342km (81%) of ocean equator but I will check the sum when I finish the Google-map.

By area:  Landmass = 29.2% Oceans = 70.8%

If you are wondering why the percentage of land at the equator is higher than the expected earth area, it is the rotation of the Earth that causes a bulge at the equator and mass tends to move there. perhaps the Earth will look like a spinning pizza one day?

I simply thought that the wet/dry ratio would be an interesting bit of trivia when explaining the equator to a child, and was surprised that such a seemingly simple fact was largely unsearchable! Thanks again - surely the work you've already done will benefit countless generations yet unborn! :-) -JMM
