Inter caetera by Wikipedia Bot 0
"Inter caetera" is a papal bull issued by Pope Alexander VI on May 4, 1493. The document was significant in the context of European colonial expansion in the Americas. It served to legitimize the territorial claims of Spain and Portugal in the New World following Christopher Columbus's voyages. The bull essentially divided the newly discovered lands outside Europe between Spain and Portugal.
The Third Principal Meridian is a north-south line of longitude that serves as a reference point for land surveying in the United States, specifically in the region west of the Ohio River. Established by the U.S. government in the early 19th century, it is one of several principal meridians used in the Public Land Survey System (PLSS). The Third Principal Meridian runs through an area that includes parts of the states of Illinois, Missouri, and Wisconsin.
Washington Meridians is a term that can refer to two different concepts in the context of geography and surveying, but it is primarily associated with the geographic coordinate system used in mapping and surveying in the United States, especially in relation to the land management practices of the General Land Office (GLO). 1. **Geographic Meridians**: In general geography, meridians are the lines of longitude that run from the North Pole to the South Pole.
Earth's crustal evolution refers to the processes and changes that have shaped the Earth's crust from its formation over 4 billion years ago to the present day. This evolution involves a combination of geological, chemical, and physical processes, leading to the development of the distinct layers of the Earth and the diverse geological features we observe today. Here are key aspects of Earth's crustal evolution: 1. **Formation**: The Earth's crust began to form shortly after the planet itself formed around 4.
Intraplate volcanism refers to volcanic activity that occurs within a tectonic plate, away from plate boundaries. Unlike the more commonly recognized volcanism associated with divergent or convergent plate boundaries, which involves processes like subduction or rifting, intraplate volcanism happens in the interior regions of tectonic plates.
Long-period tides by Wikipedia Bot 0
Long-period tides refer to tidal oscillations that occur over longer time frames compared to the more typical diurnal (daily) or semidiurnal (twice daily) tides. Specifically, long-period tides are classified as having periods of greater than one day, usually 24 hours or more, and they manifest as variations in the sea level that are influenced primarily by gravitational interactions between the Earth, Moon, and Sun.
"Old Drift" and "Young Drift" are terms used in geology and geomorphology, particularly in the context of discussing river valleys and sediment deposition. 1. **Old Drift**: This term generally refers to older sediment deposits that have settled in a river valley over a longer geological time frame. These sediments are often more compacted and may have undergone significant weathering and soil development. They can contain fossilized remains and are typically associated with earlier stages of a river's history.

Pinned article: ourbigbook/introduction-to-the-ourbigbook-project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
