Harry hess' hypothesis was hot/less dense material rises up the Earth's crust toward the mid-ocean ridges. When the seafloor breaks apart, magma is forced upward and through the cracks. It cools, and becomes a new seafloor. When it moves away from the mid-ocean ridge, it becomes denser and sinks. This helps form ridges.

Well, honey, Harry Hess didn't just stumble upon seafloor spreading like a lost puppy. He put on his thinking cap and pieced together evidence from magnetic anomalies, age dating of rocks, and the topography of the ocean floor to come up with the revolutionary idea. So, he didn't just discover seafloor spreading by accident - he used his noggin and scientific savvy to shake things up in the world of geology.
Oh, dude, Harry Hess discovered seafloor spreading by like, totally rocking the scientific world with his theory in the early 1960s. He noticed that the seafloor was getting younger as you moved away from the mid-ocean ridges, suggesting new crust was being formed there. So, like, he put two and two together and was all, "Hey, maybe the seafloor is spreading apart at these ridges!" And boom, seafloor spreading theory was born.
Well, let me tell you a little story about Harry Hess. He was a geologist who had a wonderful idea while studying the ocean floor. Harry noticed that the rocks near the mid-ocean ridges were younger than those farther away, which led him to propose the theory of seafloor spreading. It was a groundbreaking discovery that helped us understand how the Earth's crust is always moving and changing.
Harry Hess discovered seafloor spreading in the early 1960s by studying the magnetic stripes on the seafloor. He observed that the seafloor showed alternating bands of magnetic polarity, suggesting that new crust was forming at mid-ocean ridges and spreading away on either side. Hess proposed the theory of seafloor spreading as a mechanism for continental drift.
Harry Hess hypothesized that the sea floor was spreading. He explained it through the phenomena of the youngest rocks that are found only at the mid-ocean ridges. These rocks then, get progressively older when moving away from the ridge.
Harry Hess used evidence from magnetic stripes and molten material. He also used drilling samples.

Who discovered Seafloor Spreading?
Henry H. hess
When did harry hess propose seafloor spreading?
Harry Hess proposed the idea of seafloor spreading in the early 1960s, with his initial proposal being presented in 1960. This concept revolutionized our understanding of plate tectonics and the movement of the Earth's lithosphere.
Which was not included in the support for harry hess's hypothesis sea floor spreading?
Granitic strips in the ocean floor ... Novanet
What scientist helped to discover the process of sea floor spreading?
The scientist who helped to discover the process of sea floor spreading was Harry Hess, an American geologist. He proposed the theory in the early 1960s, which revolutionized our understanding of plate tectonics and the movement of Earth's crustal plates. Hess's hypothesis helped explain the geomorphology of the ocean basins and the distribution of earthquakes and volcanic activity.
Who were the two scientists who proposed the theory of seafloor spreading in the early 1960s?
While two people proposed continental drift (Alfred Wegener and Alexander du Toit), it was just ONE scientist Harry Hess that proposed the mechanism of sea floor spreading to explain how the continents actually moved.
Who discovered Seafloor Spreading?
Henry H. hess
What was the two discovery Harry Hess?
The Seafloor Spreading Theory
Who proposed the theory of seafloor spreading based on maps of the ocean floor?
The theory of seafloor spreading was proposed by Harry Hess, a geologist and Navy officer, in the early 1960s. He proposed that new oceanic crust is formed at mid-ocean ridges and then spreads outward. This theory helped to explain the mechanism behind continental drift and plate tectonics.
What is the idea that continents have moved horizontally through the seafloor to their current locations?
seafloor spreading by Harry Hess
When and where was seafloor spreading discovereand why is it important?
It was proposed in the 1960s by Harry H. Hess.
When did harry hess propose seafloor spreading?
Harry Hess proposed the idea of seafloor spreading in the early 1960s, with his initial proposal being presented in 1960. This concept revolutionized our understanding of plate tectonics and the movement of the Earth's lithosphere.
When did Hess introduce seafloor spreading?
200 BC
How did Harry Hess hypothesis explain seafloor spreading?
Harry Hess hypothesized that the sea floor was spreading. He explained it through the phenomena of the youngest rocks that are found only at the mid-ocean ridges. These rocks then, get progressively older when moving away from the ridge.
Who had the sea floor spreading theory?
Harry Hess came up with the theory of seafloor spreading . Alfred Wegener came up with the idea of continental drift NOT sea-floor spreading.
