Most of this initial heat still exists inside the Earth. The Hadean was originally defined as the birth of the planet occurring 4.0 billion years ago and preceding the existence of many rocks and life forms.
It's fascinating how the Hedean still exist in our planet. Just like the Volcanoes and people who live in countries that have a lot of volcanoes erupting near the homes. Some people can't leave where they are because they don't have anywhere nor the resources to move out.
This temperature differentiation resulted in the inner four planets of the solar system becoming rocky, and the outer four planets becoming gas giants.
Temperature is main reason what the planets are made of.
this erosion is shown as heavy wavy lines between the various numbered strata
This surprised me because I never knew that those lines are created by nature, I always thought it was human or our ancestors that did it.
unconformity
the contact between the strata and the older basement
Relative dating
is the process of determining if one rock or geologic event is older or younger than another
empirical
What is empirical and what does it do?
This data is interpreted to determine whether it contradicts or supports the hypothesis, which may be revised and tested again. When a hypothesis holds up under experimentation, it is ready to be shared with other experts in the field.
A Hypothesis is basically your thought of something that you think is going to happen in the experiment and if your idea is right, other scientists are going to use it too until another person come out with a better one to improve the results of the experiment.
Scientists share the results of their research by publishing articles in scientific journals, such as Science and Nature. Reputable journals and publishing houses will not publish an experimental study until they have determined its methods are scientifically rigorous and the conclusions are supported by evidence. Before an article is published, it undergoes a rigorous peer review by scientific experts who scrutinize the methods, results, and discussion. Once an article is published, other scientists may attempt to replicate the results. This replication is necessary to confirm the reliability of the study’s reported results. A hypothesis that seemed compelling in one study might be proven false in studies conducted by other scientists. New technology can be applied to published studies, which can aid in confirming or rejecting once-accepted ideas and/or hypotheses.
Before publishing an article a lot of scientist experts have to review and give their feedback to see if the evidence supports the claim that it's been talked about. Once it's published other scientists can use that article as evidence for their own article, they could be in favor or against it.
You have to do your own research to identify and expand your answer with previous studies that may be related to the question that you’re working on. But first you have to identify if there’s a problem or if it is a research question.
