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.
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.
Evidence that Earth's magnetic field changes can be found in the alignment of magnetic minerals in rocks on the ocean floor. As magma solidifies into new rock, the magnetic minerals within it align with the current magnetic field direction. By studying the alignment of these minerals in rocks of different ages along the ocean floor, scientists can track changes in the Earth's magnetic field over time.

Landsat helps scientists to make accurate maps of land cover, land use, changes in the Earth's surface over time, deforestation, urban development, and agriculture. These maps are crucial for monitoring environmental changes, managing natural resources, and understanding the impacts of human activities on the environment.

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.

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.

Studying the magnetic patterns of ocean floor rocks helps scientists understand the movement of Earth's tectonic plates and past changes in the Earth's magnetic field. This information is crucial for reconstructing the history of plate tectonics and understanding the processes that shape the Earth's surface.
