Ox Bow Lake Formation, As Seen By the Google Earth Time Machine

Posted by timothy on from the enhance-enhance-enhance dept.

djl4570 writes with a link to this "excellent study in the gradual change of geographic features as a river meander becomes an ox bow lake when the river current cuts through the meander. The same Google Earth feature can be used to view changes in urban and suburban geography. The historical data is a work in progress. The region I looked at only has images going back to 1993. Other regions will have a different mix and depth of data."

    Over the course of your lifetime, Europe and America will have drifted about 20 feet further apart.

    (Best estimate seems to be 5-10 cm/yr. Split the difference and multiply by 75 years; that's about 5.6 metres.)
