Why didn't scientists know a lot about the ocean floor prior to the 1950s?
Scientists didn't know much about the ocean floor before the 1950s because technology at the time limited their ability to explore deep underwater. The development of sonar technology and submarines during the 1950s allowed scientists to collect more data and map the ocean floor more accurately. Additionally, prior to this time, most research efforts were focused on studying the land, so the ocean floor remained largely unexplored.
How do scientists map features of the ocean floor using sonar?
Scientists use sonar to map the ocean floor by sending sound waves from a ship to the ocean floor. These sound waves bounce back and are picked up by a receiver on the ship, providing information about the depth and texture of the ocean floor. By analyzing the time it takes for the sound waves to return, scientists can create detailed maps of the underwater terrain.
How can scientists map the ocean floor using the satellite Geosat?
Scientists can map the ocean floor using the satellite Geosat by measuring the height of the ocean surface, which is affected by the gravitational pull of underwater features. By comparing these measurements with known gravitational models, scientists can infer the shape and depth of the ocean floor. This method, called satellite altimetry, allows for the creation of detailed maps of the seafloor topography.
How is new rock added to the ocean floor?
New rock is added to the ocean floor through a process called seafloor spreading, where magma rises from the Earth's mantle at mid-ocean ridges, cools and solidifies to form new oceanic crust. This process helps expand the ocean floor and contributes to the movement of tectonic plates.
Who were the two scientists who proposed the theory of sea floor spreading in the early 1960's?
The two scientists who proposed the theory of sea floor spreading in the early 1960s were Harry Hess and Robert Dietz. They presented the idea that new oceanic crust is formed at mid-ocean ridges and then moves away from the ridges, eventually sinking back into the mantle at subduction zones.
Why do scientists look to the ocean to research the mantle?
Why do scientists look to the ocean floor to research the mantle? Because magma from the mantle flows out of active volcanoes on the ocean floor. These underwater volcanoes have given scientists many clues about the composition of the mantle.

Why do scientists look at the ocean floor to research the mantle?
We look at the ocean floor to study the mantle because the ocean floor is made from rocks that were once part of the mantle but have be changed. These changes can be undone to a certain degree, and can allow us to study at the very least the major changes of the shallow mantle.
What thick layer covers the ocean floor?
The mantle
What is below the ocean floor?
Crust mantle core
What is the process by which ocean floor sinks into the mantle?
subduction is the answer.
What is the young ocean floor?
The Young Ocean Floor is the part of the mantle showing between the 2 split tectonic plates.
What is the geological process by which the ocean floor sinks into the mantle?
subduction
What feature of the ocean floor does the center slit stand for?
the mantle
Is there magnetic strips on the ocean floor are places where oceanic crust sink back to the mantle?
Is there magnetic stripe son the ocean floor are places where oceanic crust sink back to the mantle

What are the scientist who work on the ocean floor called?
Scientists who work on the ocean floor are called marine biologist
