Did harry hess find the mid-ocean ridge?
yes he did
Why was the ocean floor surveying conducted by Harry Hess of major geological importance?
Harry Hess helped develop the idea of seafloor spreading.
What was the theory Harry Hess proposed?
he proposed that mid-ocean ridges were areas where the floors of oceans had split apart
Who proposed the theory of seafloor spreading based on maps of the ocean floor?
The Seafloor Spreading Theory was proposed by Harry Hess.
Who was Harry Hess?
Harry Hess is a scientist who studied geology and he was born May 27, 1906 and died August 25, 1969 he was born in New York City and he discovered how the first layer of Earth (the crust) forms
Did harry hess find the mid-ocean ridge?
yes he did
What evidence did harry hess use to prove sea-floor spreading?
Harry Hess was mapping the floor of the ocean when he found a mountain range in the middle of the ocean. He found that the land nearest to the ridge was younger compared to the fact that the farther away land was from the ridge, the older it dated. He used this to find that the mountain ridge was creating new land and pushing aside the old land.
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.
What process did harry hess discover to make alferd wegners theory more accepted?
He discovered that the ocean floor moves like a conveyor belt, carrying the continents with them. This process begins at the mid-ocean ridge. Old oceanic crust go back to the mantle through trenches and molten material comes out of the mid-ocean ridge, making new crust. Harry Hess called this constant process sea-floor spreading.
Why was the ocean floor surveying conducted by Harry Hess of major geological importance?
Harry Hess helped develop the idea of seafloor spreading.
What did harry hess propose?
Harry Hess proposed an explanation that tied together data on the age of ocean rocks, sediment thickness, and magnetic striping.
Where can divergent divergent boundary be found?
Most divergent boundaries can be found on the ocean floor. divergent boundaries create Rift Valleys An example of this is the Mid-Atlantic Ridge discovered by Harry Hess.
How did Harry Hess discover seafloor spreading?
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.
What technology did Harry Hess use to map the ocean floor?
probably sonar
How did harry hess hypothesis explain seafloor movement?
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.
