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:
Treating POTS can be tricky, even with a treatment plan that is created by a highly experienced physicians. In my experience, the most effective treatments for POTS syndrome are those that don’t require prescription medication – often referred to as natural, homeopathic, or lifestyle treatments. In some circumstances, patients also gain relief by supplementing a lifestyle-driven POTS treatment strategy with various medications. In this article, you’ll find an exhaustive list of treatment options available for POTS, all of which have been proven effective in peer-reviewed medical publications. Many of our readers have found it helpful to share this resource with their physician. If that helps you get on the right track for relieving POTS symptoms and regaining control over your life, feel free to use this resource in any way that’s helpful. Also, be sure to checkout the infographic below that explains primary treatment methods in an easy-to-understand format.

Answer:
Families and social customs have the most influence over the production of goods and services in a traditional economy.
Explanation:
A is not correct because this type of economy is a transitional type where both the private sector and the government have a big influence on production.
B is correct because this is the economic type where the families and social custums, or rather tradition, have the biggest influence, with change often being viewed with skepticism and rejection.
C is not correct because this is an economic type that is found in communist countries, and the government has the main say in the production.
D is not correct because this economic type promotes perfect competition, with all businesses being owned and all decisions made by the private sector.
