Which was not included in the support for harry hess's hypothesis of sea-floor spreading?

One key piece of support that was not included in the initial support for Harry Hess's hypothesis of seafloor spreading was the mechanism of plate tectonics. This idea was developed and integrated into the theory of seafloor spreading by geologists like Robert Dietz and J. Tuzo Wilson at a later stage.


Which was not included in the support for Harry Hesss hypothesis of sea-floor spreading?

One key piece of evidence not included in support of Harry Hess's hypothesis of sea-floor spreading was the discovery of paleomagnetic data. While Hess's theory focused on the creation of new oceanic crust at mid-ocean ridges and the recycling of crust at subduction zones, the paleomagnetic records provided insights into the historical movement of continents and the magnetic orientation of rocks, which later supported the theory of plate tectonics. Other evidence, such as the age of oceanic crust and the distribution of fossils, played a more direct role in supporting his hypothesis.


What evidence do scientists have that verify that indeed the earths plates are spreading at the mid-ocean ridge?

Scientists have gathered evidence for plate spreading at mid-ocean ridges through various methods. One key piece of evidence is the measurement of magnetic striping on the ocean floor, where symmetrical patterns of magnetic minerals record the Earth's magnetic reversals as new crust forms and pushes older crust away. Additionally, seismic data and direct measurements of seafloor spreading rates using GPS technology confirm that the plates are indeed moving apart. Oceanic rock samples from the ridge also show that younger rocks are found closer to the ridge, supporting the idea of new material being created there.


What evidence do scientists have that verify that indeed the earths plated are spreading at the mid-ocean ridge?

Scientists have gathered evidence of seafloor spreading at mid-ocean ridges through several key observations. One major piece is the symmetrical pattern of magnetic striping on either side of the ridges, which reflects reversals in Earth's magnetic field as new crust forms. Additionally, age dating of ocean floor sediments shows that the youngest rocks are located at the ridge, with older rocks found further away. Seismic data also indicate tectonic activity, confirming the movement of plates in these regions.


Why is sea floor spreading an important piece of evidence in support of plate tectonics?

The view of a fourteen year old...Sea floor spreading is the process where new oceanic crust is formed. This is achieved by the upwelling of magma at mid oceanic ridges. This can cause a continuing displacement of ocean crust - almost systematic. As for why it is important... I'm not sure.The view of a 14 yr old 9th grader...sea-floor spreading is important because it led scientist to develop and accept plate tectonic theory

What is the circumstantial evidence that supports the hypothesis that high fructose corn syrup is harmful to humans?

The circumstantial evidence that supports that hypothesis that high fructose corn syrup is harmful to humans is the fact that obesity is so high. The instances of diabetes is another piece of circumstantial evidence that supports this.

Which evidence best supports this counterclaim?

The evidence that best supports a counterclaim is one that directly challenges a key piece of evidence or argument used to support the original claim. This evidence should be credible, relevant, and clearly demonstrate an alternative perspective or interpretation.


What transforms a piece of information into evidence?

Information transforms into evidence when it is relevant, reliable, and credible. Evidence is information that supports a claim or conclusion, and it is obtained through research, observation, or experience. The quality of evidence is determined by its accuracy, specificity, and consistency.

What evidence supports the theory of Earth's rotation?

The theory of Earth's rotation is supported by several pieces of evidence. One key piece of evidence is the Coriolis effect, which causes moving objects on Earth to curve due to the planet's rotation. Another piece of evidence is the difference in day and night caused by the rotation of Earth on its axis. Additionally, the flattening of the Earth at the poles and bulging at the equator is also evidence of Earth's rotation.


What is one major piece of evidence that supports the validity of the Big Bang theory?

One major piece of evidence supporting the validity of the Big Bang theory is the cosmic microwave background radiation, which is a faint glow of radiation that fills the universe and is considered a remnant of the early stages of the universe's expansion.


When writing an essay a writer s best piece of evidence should appear in which paragraph?

The writer's best piece of evidence should typically appear in the body paragraphs of the essay. It should be placed where it best supports the main argument or thesis statement. Introducing the evidence in a well-structured and logical manner will strengthen the overall persuasiveness and credibility of the essay.
