Causes. Back pain is a symptom. Common causes of back pain involve disease or injury to the muscles, bones, and/or nerves of the spine. â¢ (a nerve is directly irritated), often due to a herniation (or bulging) of the disc between the lower back bones.
What is the difference between a creek and a crick? Please add where you are from in your answer. One is a body of flowing fresh water smaller than a river, and the other is a pain in the neck. Unless you're from Appalachia, in which case the latter (crick) is an alternative pronunciation of the former (creek). I have yet to find corroborating evidence of this sense/connotation of the word. I'm mostly from California, and out here we call them creeks (rhymes with leeks), regardless of size.
Sandstone Basics. Sandstone is a category of rock made from sediment (a sedimentary rock). The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock.andstone with a lot of matrix is called poorly sorted. If matrix amounts to more than 10 percent of the rock, it is called a wacke (wacky). A well-sorted sandstone (little matrix) with little cement is called an arenite. Another way to look at it is that wacke is dirty and arenite is clean.
