More recent studies of continental matchups and the magnetic ages of ocean-floor rocks have enabled us to reconstruct the history of the break-up of Pangea.
In simple terms, Pangea was broken a part because of the magnetic ages on the oceans floor? Or is that just a part of it whereas it is much more complex?
measuring the flow of heat from the ocean floor.
Measuring heat from the ocean floor shocks me. I do not believe that this would be a thing or could be recorded.
paleomagnetism, the record of Earth’s magnetic field through time
I am curious to learn about this process. I wonder how over time the paleomagnetism has changed or been effected.
One proponent of this idea
What was the proponent given by Ernest Ingersoll?
geosynclines
I am not too sure on what this is... What does this entail?
it came with its own set of problems.
I feel that everything could result in problems but I wonder how many problems occurred after the hypothesis?
it must also be shrinking.
Why was this an assumption? Or why was this the response specifically?
Eon is the largest division of time, followed by era, period, epoch, and age.
I still am not confident in the understanding of geologic time but this is a semi break down that clarifies.
Ichnology is specifically the study of prehistoric animal tracks
I did not know this was the name of tracing animal tracks.
There are three types of unconformities, nonconformity, disconformity, and angular unconformity.
I did not know there was so much layers to Earth's processes. These types of unconformities are not some that I have heard of before.
However, it is hard to know if Earth processes could have changed the water’s isotopic signature over the last 4-plus billion years. It is possible that all three sources contributed to the origin of Earth’s water.
I wonder how hard it is to track Earth's process to see how it effects the water process.
Fusion is a steady and predictable process,
Is this measured throughout scientific discovery? The process of fusion is considered steady and predictable but how did this come to conclusion?
Another process must be responsible for creating the other 90 heavier elements.
I think this is very interesting how the big bang theory is the root cause for life on Earth according to science. I am curious how stellar evolution is responsible for the making of heavier elements.

I am interested to learn more about this because I do not remember learning too much about this and it seems very complex.
Earth System Science includes five basic systems (or spheres), the Geosphere (the solid body of the Earth), the Atmosphere (the gas envelope surrounding the Earth), the Hydrosphere(water in all its forms at and near the surface of the Earth), the Cryosphere (frozen water part of Earth), and the Biosphere (life on Earth in all its forms and interactions, including humankind)
I understand the Earth and science has a lot of parts and aspects to it, but I did not realize how many different things play into each others systems and ways of works.
Deductive reasoning starts with generalized principles and logically extends them to new ideas or specific conclusions.
I think I had the hardest time grasping deductive and inductive reasoning.
Formulate a question or observe a problem Apply objective experimentation and observation Analyze collected data and Interpret results Devise an evidence-based theory Submit findings to peer review and/or publication
I feel this version of scientific method has changed or become more complex than what I remember from learning in school.
Humans are biased by nature, so they cannot be completely objective; the goal is to be as unbiased as possible.
I understand how humans are biased by nature but it amazes me how direct this statement is and how others might not fully understand this concept.
