#AlphabetChallenge #WeekKforKn "Knowledge is power" (commonly attributed to Sir Francis Bacon 1597) Barter Books in Alnwick, Northumberland. It is one of the largest second hand bookshops in Europe. See Alt text for more #classicmono #barterbooks #alnwick #northumberland #photography #eastcoastkin
A black and white image of a walkway with many wooden bookshelves either side of it. The genre of each bookshelf is written in capital letters on the outside of the bookshelf.
This is at Barter Books in Alnwick,. Northumberland, England. It is one of the largest second hand bookshops in Europe.
The bookshop is housed in the town's old Victorian railway station, which was decommissioned in 1968. 
Lines from poems and quotes, such as those from the Song of Solomon seen in the image, are displayed throughout the shop. 
The text displayed prominently on a banner above the walkway for each row in the image is a quote from the Song of Solomon: "Rise up, my love, my fair one, and come away. For, lo, the winter is past, the rain is over and gone; the flowers appear on the earth; the time of the singing of birds is come, and the voice of the turtle...". 
The shop operates on a barter system, allowing customers to trade their own books for store credit. 
It is known for its cozy atmosphere, featuring comfortable seating areas, open fireplaces, and a model railway that runs above the bookshelves

There are few visible features at the surface, and from here the slow process of chemical weathering begins. Many articles jump straight to the processes beyond the first stage, but I liked the description in the Encyclopedia of the Environment 👉 www.encyclopedie-environnement.org/en/zoom/he-m...

The mechanisms of karstification - Encyclopedia of the Environment
Two mechanisms are at the basis of karstification: the flow of water into the carbonate rock and the dissolution of carbonates by acidic water

From my friend @climatechris.bsky.social: "A glacier’s weight braces the slope it sits against, and permafrost joins the fractured rocks above it. When you lose both the permafrost and the glacier, the mountain loses its structural support."

The Ice Was Holding the Mountain Up
We keep talking about glaciers as water towers. In steep terrain they are also load-bearing walls, and the strength of the joints holding the rock together drops 17 percent for every degree of warming
