Land added to Laurentia during the Grenville orogeny. The first mountain-building tectonic plate collision that initiated the construction of what are today the Appalachian Mountains occurred during the Mesoproterozoic era at least one billion years ago when the pre-North-American craton called Laurentia collided with other continental segments, notably Amazonia.
Tectonic uplift is the geologic uplift of Earth's surface that is attributed to plate tectonics. While isostatic response is important, an increase in the mean elevation of a region can only occur in response to tectonic processes of crustal thickening (such as mountain building events), changes in the density distribution of the crust and ...
The Alleghanian orogeny, a result of three separate continental collisions. USGS. The immense region involved in the continental collision, the vast temporal length of the orogeny, and the thickness of the pile of sediments and igneous rocks known to have been involved are evidence that at the peak of the mountain-building process, the Appalachians likely once reached elevations similar to ...
The Alpine orogeny is caused by the continents Africa, Arabia and India and the small Cimmerian Plate colliding (from the south) with Eurasia in the north. Convergent movements between the tectonic plates (the African Plate, the Arabian Plate and the Indian Plate from the south, the Eurasian Plate and the Anatolian Sub-Plate from the north, and many smaller plates and microplates) had already ...
The Uplift Universe is a fictional universe created by American science fiction writer David Brin. A central feature in this universe is the process of biological uplift. His books which take place in this universe are: Sundiver (1980) Startide Rising (1983) The Uplift War (1987) The Uplift Storm trilogy (sometimes called the Uplift Trilogy):

The Uplifters, long dormant, now meets regularly at The Los Angeles Athletic Club. Once an all male group, it is now run by two women. The club continues to uphold their founding motto - "To Uplift Art and Promote Goodfellowship," - while also promoting a contemporary spirit of inclusivity, and outward-facing engagement with the DTLA community.
