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.

Sedimentary structures (cross‑bedding, mud cracks, ripple marks, worm trails and burrows, fossil shells) are not usually visible in hand specimens, but are noticeable in outcrops. Color is not usually significant, because as little as 3% hematite (iron oxide) gives a rich red color. Some pinkish sandstones get their color from feldspar.

Mud daubers do have the capacity to sting. However, mud dauber stings are unlikely and rare because they are not an aggressive species of wasp.

Sedimentary structures provide evidence of the actions of the physical environment that are preserved in sedimentary rocks. Examples include ripple marks, cross-bedding, fossils uniformly oriented by currents, scours left by objects that were dragged by water flow, mud cracks formed in drying sediments, and even the impressions of raindrops made in ancient soft sediments before they ...Sand beds in sand-mud rhythmic strata can play a lubricative role on crack growth and provide enough sandy deposits for filling cracks. (5) Mud crack growth usually produces bifurcation and bifurcation angles which are mostly 120° or 90° that are related to sediment heterogeneity and released energy.

Aug 9, 2023 · Curiosity is gradually ascending the sedimentary layers of Mount Sharp, which stands 3 miles (5 kilometers) high in Gale Crater. The rover spotted the mud cracks in 2021 after drilling a sample from a rock target nicknamed “Pontours,” found within a transitional zone between a clay-rich layer and one higher up that is enriched with salty minerals called sulfates. Mud cracks Pleistocene mud cracks between sand dunes at Mesquite Dunes, Death Valley, California. The desiccation of mud produces shrinkage when stresses induced by volume loss through evaporation are greater than the cohesive strength of the mud. Cracks initiate and grow, dividing the mud up into a series of irregular polygons.

[3]Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call "mud." This composition places shale in a category of sedimentary rocks known as " mudstones ."
