Found myself today in a discussion on the right definition for one of my favorite rocks and least favorite terms - chalk. Give me your definitions! I want to see how conflicting they will get. #Geology #Rock #Chalk
Friends in town for the weekend and we stopped into the #MapleGroveMN chalk fest event on Saturday to see how it was going. The artists still had some time to work so theres a possibility of heading back down today to see them complete. #ch
The #crochet #chalk #afghan on my front walk grew again; and faded a little, and took a little bit of light rain. But it's still there.
What “chalk” means
Wiktionary · Wikipediachalk/t͡ʃɔːk/
- nounA soft, white, powdery limestone.
- verbTo apply chalk to anything, such as the tip of a billiard cue.
Chalk is a soft, white, porous, sedimentary carbonate rock. It is a form of limestone composed of the mineral calcite and originally formed under the sea by the accumulation and lithification of hard parts of organisms, mostly microscopic plankton, which had settled to the sea floor. Chalk is common throughout Western Europe, where deposits underlie parts of France, and steep cliffs are often seen where they meet the sea in places such as the Dover cliffs on the Kent coast of the English Channel
