"Magnetic Polarity: the North and South magnetic poles have switched positions throughout Earth's history... the record of magnetic polarity in the rocks of the ocean floor provided unequivical support for the seafloor spreading hypothesis." - as quoted in chp. 4, pg. 94, from the textbook "The Good Earth: Introduction To Earth Science"

Because of sea floor spreading
Because 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.
One key piece of evidence not included in the support for Harry Hess's hypothesis of sea-floor spreading was the lack of understanding of the mechanisms driving plate tectonics at the time. Additionally, Hess's hypothesis did not initially account for the role of subduction zones and the recycling of oceanic crust, which are crucial to the overall dynamics of plate movements. The technology to measure the age of oceanic rocks and the discovery of magnetic striping on the ocean floor also emerged later, providing more comprehensive support for the theory.
people here are stupid , really the answer is not hi
dumb question. don't want to write it all
If your data does not support your hypothesis, it means that there is not enough evidence to conclude that your hypothesis is true. In such cases, you may need to reconsider your hypothesis, collect additional data, or revise your experimental approach. It is important to acknowledge and learn from results that do not support your initial hypothesis in order to refine your research and understanding.
An experiment can support a hypothesis by providing data that aligns with the predicted outcomes, demonstrating a consistent relationship between the variables involved. Conversely, it can fail to support a hypothesis if the results do not match the expected patterns or if the data shows no significant effect. Even when a hypothesis is not supported, valuable insights can be gained, leading to revisions or new hypotheses. Overall, the outcomes of an experiment contribute to the iterative process of scientific inquiry.
One aspect not included in the support for Harry Hess's hypothesis of sea floor spreading was the lack of direct evidence of the mechanisms driving the process, such as mantle convection. Additionally, the age and magnetic anomalies of the ocean floor were not fully understood at the time, which limited the initial acceptance of his ideas. Furthermore, the concept of plate tectonics, which later provided a comprehensive framework for understanding sea floor spreading, was not yet developed during Hess's proposal in the early 1960s.
An experiment might not support a hypothesis even if the hypothesis is correct because if the conclusion
If your hypothesis is totally incorrect then it is quite likely that the data will not support it.
