Alfred Wegener's theory was proven When Harry Hess found something that would be able tho explain the continental drift.

Alfred Wegener's theory of continental drift was proven when Henry Hess made a mechanism that could explain continental drift.

Allie H. said...

The continental drift theory was supported and also looked at again when Henry Hess came up with the idea of seafloor spreading. It proved that Alfred Wegener wasn't a crazy as they thought.

Alfred wegener theory was proven by Harry Hess who learn about the plates under the surface

Henry hess make a mechanism that proved his theory

His theory was proven when Harry Hess discovered mechanism which backed up the Wegener's theory.

Alfred weganer therey was proven by Henry hess using sonar to study the ocean floor

It was later proven by Henry Hess that techtonic plates created this.

when harry hess discovered the tectonic plates

Cadence W. said...

Fro when harry hess studied the sea floor and saw that there was an active volcano making new land which made the tectonic plates move.

Alfred Wegener's theory was proven by henry hess. he had fond a meconisam to prove contanintal drift

There were the same dinosaur fossils on different fossils in different parts of the earth, and the fact of seafloor spreading, as well as other pieces of evidence.

He proved it by using evidence to support his hypothesis. Also when Henry Hess came up with the theory seafloor spreading.
