Mud cracks
If you like to crack your knuckles, people may have told you to stop because it causes arthritis. And if you hate the sound of knuckles cracking, maybe you’ve even used this reason to get other people to stop doing it.
Mudcracks (also known as mud cracks, desiccation cracks or cracked mud) are sedimentary structures formed as muddy sediment dries and contracts. Crack formation also occurs in clay-bearing soils as a result of a reduction in water content.
