Specific Contributions to Plate Tectonic Theory / Solid Earth Geophysics. During the 1950’s and 1960’s, Dietz was an advocate for both the motion of the sea floor and later Sea Floor Spreading, a term he coined in his 1961 Nature article entitled Continent and Ocean Basin Evolution by Spreading of he Sea Floor.
What did Robert S Dietz discover?
fracture zone
Dietz’s discovery in 1952 of the first fracture zone in the Pacific, which he related to deformation of the Earth’s crust, led him to hypothesize that new crustal material is formed at oceanic ridges and spreads outward at a rate of several centimetres per year. Subsequent work confirmed this suggestion.
What did Hess and Dietz do?
Hess and Robert S. Dietz suggested that new ocean crust was formed along mid-oceanic ridges between separating continents; and second, Drummond H. Matthews and Frederick J.
Who is the American geologist who introduced the concept of seafloor spreading together with Robert Dietz?
Harold Hammond Hess
History of study The idea that the seafloor itself moves and also carries the continents with it as it spreads from a central rift axis was proposed by Harold Hammond Hess from Princeton University and Robert Dietz of the U.S. Naval Electronics Laboratory in San Diego in the 1960s.
What is Alfred Wegener theory?
In the early 20th century, Wegener published a paper explaining his theory that the continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other. He called this movement continental drift.
Who is Harry Hammond?
Harry Hammond Hess (May 24, 1906 – August 25, 1969) was an American geologist and a United States Navy officer in World War II who is considered one of the “founding fathers” of the unifying theory of plate tectonics….

Who are Harry Hess and Robert Dietz?
Dietz, born in Westfield, New Jersey, was a marine geologist, geophysicist and oceanographer who conducted pioneering research along with Harry Hammond Hess concerning seafloor spreading, published as early as 1960–1961.
What did Harry Hess discover?
Harry Hess was a geologist and Navy submarine commander during World War II. Part of his mission had been to study the deepest parts of the ocean floor. In 1946 he had discovered that hundreds of flat-topped mountains, perhaps sunken islands, shape the Pacific floor.
Who is Robert Dietz and what did he do?
Robert S. Dietz. Robert Sinclair Dietz (September 14, 1914 – May 19, 1995) was a scientist with the US Coast and Geodetic Survey. Dietz was a marine geologist, geophysicist and oceanographer who conducted pioneering research along with Harry Hammond Hess concerning seafloor spreading, published as early as 1960–1961.
What did Dietz contribute to the field of geology?
Dietz made major contributions in three general areas of Earth and planetary sciences: marine geology and geomorphology; continental drift and plate tectonics; and planetary geology, particularly the study of impact structures. He traveled widely in the United States and around the world, was a keen observer, and had a gift for finding adventure.
Who is Robert Sinclair Dietz?
On September 14, 1914, US marine geologist, geophysicist and oceanographer Robert Sinclair Dietz was born.
Where did Frank Dietz grow up?
Born and raised in Westfield, New Jersey, Dietz graduated in 1932 from Westfield High School. In later work he became interested in meteorite impacts, was the first to recognize the Sudbury Basin as an ancient impact event, and discovered a number of other impact craters.
