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.
What else can I help you with?
What three pieces of evidence did Harry Hess gather to prove that seafloor spreading was taking place?
Magnetic stripes on the seafloor showed alternating patterns of normal and reversed polarity, matching Earth's magnetic field reversals. Age dating of seafloor rocks revealed that rocks were youngest along mid-ocean ridges and oldest near continental margins. Sediment thickness on the seafloor was thinnest at mid-ocean ridges and thickest near the continents, supporting the idea of seafloor spreading.
How do scientists prove seafloor spreading?
Scientists prove seafloor spreading through various methods, including mapping of magnetic stripes on the ocean floor, analysis of seismic activity, and examination of rock samples collected from the ocean crust. These techniques provide evidence of tectonic plate movement and the creation of new oceanic crust at mid-ocean ridges.
Did seafloor spreading prove the theory of continental drift?
Yes, seafloor spreading provided concrete evidence for the theory of continental drift proposed by Alfred Wegener. It demonstrated that new oceanic crust was continuously forming at mid-ocean ridges, pushing the continents apart over time. This supported the idea that continents were once connected and have since moved to their current positions.
In 1960 harry hess proposed the theory of?
sea floor spreading. that the sea floor was spreading and there for pushing the continents .he continued studying Alfred Wegener's theory and became more knowledgeable about then started gathering information to prove the theory and did
What technology did Harry Hess use to prove the theory of Plate Tectonics?
Harry Hess used sonar and another device still not found. Hey well he actually used an echo sounding device onboard the ship U.S.S Cape Johnson in which he commandered. Hess kept the echo sounding device on throughout his journey and he gained thousands of miles of echo sound maps of the ocean floor. Malkee xx
What did the magnetic strips prove in seafloor spreading?
They proved that the seafloor was spreading.
What are 3 things of evidence that scientists have that prove the ocean is spreading?
1) seafloor spreading 2) continental drift 3 i only found 2

This supported the idea that continents were once connected and have since moved to their current positions.
What tools were used to prove seafloor spreading?
Tools such as sonar mapping, geologic sampling, and paleomagnetism studies were used to provide evidence for seafloor spreading. Sonar mapping allowed for the creation of detailed maps of the ocean floor, revealing features such as mid-ocean ridges and deep-sea trenches. Geologic sampling involved collecting rock samples from the ocean floor to study their age and composition. Paleomagnetism studies focused on analyzing the alignment of magnetic minerals in rocks, providing evidence of past changes in Earth's magnetic field that support the idea of seafloor spreading.
Why was the theory of seafloor spreading rejected?
The theory of seafloor spreading was not rejected; in fact, it is widely accepted in the field of geology. Proposed by Harry Hess in the early 1960s, seafloor spreading explains how new oceanic crust is formed at mid-ocean ridges and then moves away as tectonic plates drift apart. This concept revolutionized our understanding of plate tectonics and the Earth's geology.
What scientist used sonar to prove seafloor spreading under the Atlantic ocean?
Harry Hess, an American geologist and Navy officer, used sonar to study the seafloor of the Atlantic Ocean. He discovered the presence of mid-ocean ridges and proposed the theory of seafloor spreading in the early 1960s, which played a crucial role in the development of the theory of plate tectonics.
How does magnetic stripes prove seafloor spreading?
Magnetic stripes on the seafloor provide evidence for seafloor spreading because they show alternating bands of normal and reversed polarity along mid-ocean ridges. These stripes form as new oceanic crust is created at mid-ocean ridges, with the Earth's magnetic field aligning minerals in the crust in the direction of the prevailing polarity at the time of its formation. By collecting and analyzing samples from the ocean floor, scientists can observe these magnetic patterns and confirm the process of seafloor spreading over geologic time scales.
How did the seafloor spreading help prove the continental drift?
Seafloor spreading provided evidence for continental drift by showing that new oceanic crust is formed at mid-ocean ridges, pushing older crust away. This process helped explain how continents could move and supported the idea of plate tectonics. The pattern of magnetic stripes on the seafloor also matched with predictions based on the movement of continents, further supporting the theory of continental drift.
What is sea floor spreading and what evidence do we have to prove it is happening?
Magnetic minerals on the ocean floor.
