The ocean floor preserve evidence of past magnetic reversals because c) the ocean floor is uniformly old, preserving the earth's 4.6 billion history.
<h3 /><h3>What subjects need to be studied to study the earth's magnetism?</h3>
Paleomagnetism is the study of naturally occurring residual magnetism in rocks with the goal of understanding the strength and direction of the Earth's magnetic field in the geologic past and understanding the motion history of plates. Paleomagnetic fields have played a large role in confirming undersea propagation, through the discovery and understanding of seafloor anomalies. In the 1960s, geophysicists studied the magnetic properties of the ocean floor and began to discover some amazing properties.
The seabed has a system of linear magnetic anomalies in which a "band" has all its magnetic minerals oriented in the same way as the current magnetic field and the magnetic minerals in the bands alternating is oriented in the opposite direction. These bands are oriented parallel to the mid-ocean ridge system; where the ridges compensate for the transform error, the anomalies are also compensated. Symmetrical anomalies are found on either side of the ridge, and similar symmetry is found in ridges around the world.

Answer:
When we talk about the <u>visible electromagnetic spectrum</u>, we know it starts in <u>violet-blue</u> and ends in <u>red</u>.
In this context the astronomer <u>Edwin Powell Hubble </u>observed several celestial bodies, and when obtaining the spectra of distant galaxies he observed that the spectral lines were displaced towards the red one (red shift), whereas the nearby stars showed a spectrum displaced to the blue one.
From there, it was deduced that the farther a body in the universe is, the more redshifted it is in its spectrum. This effect is due to the dilation and contraction of time by speed according to the relativity.
Now, the Sun is a massive star and the Earth is at certaind distance from it, therefore <u>time passes slower in the Sun than on Earth</u>. This causes the spectrum of the Sun to present lines with a lower frequency or longer wavelength than normal, that is, more towards red.
I think it will be Melanesia
