What did Marie Tharp discover?
In 1977, Tharp and Heezen published the first complete world map of the ocean floors. Their work helped to prove the theory of plate tectonics, the idea that the continents move over time, which was controversial until then. The discovery revolutionized our understanding of how nearly everything on the planet works.
When did Marie Tharp discover?
July 30, 1920: Marie Tharp, the Woman who discovered the Backbone of Earth – Scientific American Blog Network.
What did Marie Tharp do as a child?
Early Life and Education Her father worked as a soil surveyor, which means he made maps based on the soil data he collected. Tharp often went out into the field with her father, so she was introduced to mapmaking at an early age.
Where is Marie Tharp from?

Why is Marie Tharp important?
Marie Tharp produced one of the world’s first maps of the ocean floor. Despite being a woman in a male dominated career, her work helped bring to life the unknown ocean world, and helped prove important information about our earth’s development.
What did Marie discover that was the smoking gun for continental drift?
That symmetry was the smoking gun that confirmed the theory of seafloor spreading and set the stage for our understanding today of plate tectonics.
Who proved Marie Tharp wrong?
4. Jacques Cousteau accidentally helped to prove her right. The famous ocean explorer Jacques Cousteau didn’t believe the rift valley really existed. So he set sail into the Atlantic with an underwater camera rig, intending to prove Tharp and Heezen wrong.
How did Marie Tharp prove continental drift?
She spent most of her career working in the background. Today, we openly recognize her contribution to oceanic exploration. Tharp, in partnership with Heezen, helped prove the theories of continental drift. But the most notable thing is that she helped map and illuminate a once unknown world – the ocean floor.
Who is the founder of the continental drift hypothesis?
The continental drift hypothesis was developed in the early part of the 20th century, mostly by Alfred Wegener. Wegener said that continents move around on Earth’s surface and that they were once joined together as a single supercontinent.
How did Marie Tharp prove Continental Drift was real?
Marie Tharp’s maps helped prove continental drift was real. But her work was initially dismissed as “girl talk” Marie Tharp’s map helped vindicate plate tectonics, but her work was initially dismissed as “girl talk.” (Lamont-Doherty Earth Observatory and the estate of Marie Tharp)
What did Alfred Wegener believe about continental drift?
The continental drift hypothesis was developed in the early part of the twentieth century, mostly by Alfred Wegener. Wegener said that continents move around on Earth’s surface and that they were once joined together as a single supercontinent. While Wegener was alive, scientists did not believe that the continents could move.
What kind of evidence is there for continental drift?
In the early part of the 20th century, scientists began to put together evidence that the continents could move around on Earth’s surface. The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.
