How do scientists use to determine the age of a rock on the ocean floor?
Scientists use a method called radiometric dating to determine the age of rocks on the ocean floor. This technique involves measuring the proportions of certain radioactive isotopes and their decay products within the rock to calculate how long it has been since the rock formed. By analyzing these ratios, scientists can estimate the age of the rock.
What are the scientist who work on the ocean floor called?
Scientists who work on the ocean floor are called marine biologist
How do scientists make maps of the ocean floor?
Sonar
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.

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 do scientists study the ocean?
They send underwater submarines to study the ocean floor.
How were scientists able to use rock on the ocean floor to determine that the Earth and magnetic field has changed direction?
Scientists studied the alignment of magnetic minerals in oceanic rocks to determine that the Earth's magnetic field has undergone reversals in polarity. By analyzing the magnetic "stripes" on the ocean floor, they found alternating bands of rocks with normal and reversed polarity, suggesting that Earth's magnetic field has changed direction over time.
What technology did Harry Hess use to map the ocean floor?
Harry Hess used echo sounding technology to map the ocean floor. This technology involved sending sound waves from a ship and measuring the time it took for the sound waves to bounce back, allowing scientists to determine the depth of the ocean floor and create detailed maps.

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.
Which method is not a technique currently used by ocean scientists to map the topography of the ocean floor?
Satellite imagery is not typically used by ocean scientists to map the topography of the ocean floor, as it cannot penetrate the water to provide detailed depth information. Instead, methods such as multibeam sonar and lidar are commonly used to create detailed maps of the ocean floor.
