How are magnetic patterns in sea floor rock evidence of seafloor spreading?

Magnetic alignment of rocks, in alternating strips that run parallel to ridges, indicates reversals in Earth's magnetic field and provides further evidence of seafloor spreading.


What type of evidence can best support this statement?

To effectively support a statement, empirical evidence such as statistical data, case studies, or experimental results is ideal, as it provides measurable and observable backing. Additionally, expert testimonials or peer-reviewed research can lend credibility and depth to the argument. Qualitative evidence, such as anecdotes or historical examples, can also enhance understanding but should complement quantitative data for a more robust support.


What is a supporting fact?

A supporting fact provides evidence or information that reinforces a main point or argument. It helps to strengthen the validity of a claim or statement by offering additional details, examples, or data to back it up.


How is magnesium used to support the theory of seafloor spreading?

Magnesium is used to support the theory of seafloor spreading because as new oceanic crust forms at mid-ocean ridges, it contains higher levels of magnesium compared to older crust. This can be observed through magnetic anomalies in the oceanic crust, where variations in magnesium content create distinct magnetic stripes that align with the spreading centers. This provides evidence that new crust is being continuously generated at mid-ocean ridges, supporting the process of seafloor spreading.


Which statement provide evidence that earth has been struck by meteoroid in the past?

The question cannot be answered properly, because you did not list the statements that we're supposed to choose from. However, the presence of meteoric impact craters such as Barringer Meteor Crater in Arizona provides fairly conclusive evidence of past impacts.

How do the ages of the rocks on the seafloor support the theory of seafloor spreading?

The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.


Used as evidence for sea-floor spreading?

Magnetic striping on the ocean floor is used as evidence for seafloor spreading. As new oceanic crust forms at mid-ocean ridges, Earth's magnetic field is recorded in the rocks in alternating patterns of normal and reversed polarity. This provides support for the idea that new crust is continuously being created at mid-ocean ridges and spreading away in opposite directions.

What provides the basis for everything else in the expository essay?

The thesis statement typically provides the central argument or main idea that serves as the basis for everything in the expository essay. It outlines the purpose of the essay and guides the content and structure of the writing. Each paragraph and piece of evidence should support and relate back to the thesis statement.


What is a persuasive thesis statement?

A persuasive thesis statement presents a claim or argument and aims to persuade the reader to agree with the position being presented. It is typically clear, specific, and provides a roadmap for the rest of the essay. The statement should be backed up with evidence and logical reasoning to convince the reader of its validity.


How magnetic reversal provides evidence for seafloor spreading?

The Earth's crust is broken into many slowly moving plates. Sea floor spreading occurs at the mid ocean ridge where two plates are moving away from each other. Magma rises up from below and cools to form new seafloor rock
