Silt may occur as a soil or as suspended sediment also known as suspended load in a surface water body. It may also exist as soil deposited at the bottom of a water body. Clays are formed from thin plate-shaped particles held together by electrostatic forces, so there is a cohesion.
Silts and clays are distinguished mechanically by their plasticity the deformation of a material undergoing non-reversible changes of shape in response to applied forces. Mud is a mixture of water and some combination of soil, silt, and clay.
Ancient mud deposits harden over geological time to form sedimentary rock such as shale or mudstone generally called lutites.
When geological deposits of mud are formed in estuaries the resultant layers are termed bay muds. Mud is closely related to slurry and sediment. Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. The composition of sand is highly variable, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica silicon dioxide, or SiO2 , usually in the form of quartz.
The second most common form of sand is calcium carbonate , for example aragonite, which has mostly been created, over the past half billion years, by various forms of life like coral and shellfish.
It is, for example, the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years, like the Carribean. Soil is composed of particles of broken rock that have been altered by chemical and mechanical processes that include weathering, erosion and precipitation. Soil is altered from its parent rock due to interactions between the lithosphere, hydrosphere, atmosphere, and the biosphere. It is a mixture of mineral and organic materials that are in solid, gaseous and aqueous states.
Soil is commonly referred to as earth or dirt; technically, the term dirt should be restricted to displaced soil. At its most general, mud could really be said to be any mixture of particles and a liquid. Most typically it is fine organic and mineral particles of earth dirt , plus water. IOW, typically mud has fine, clay particles, not coarse, sand particles. But mud is a term that can be used in different ways. One common use of the term mud refers to wet cement or mortar.
Most likely you would say that your hair was covered or more poetically plastered with wet sand and that it became caked with sand if left to dry. This could be called a mud but probably would not be. A lot of heavy, dirty gloop is called mud. For example there are anode muds in electroplating which is gunk which collects during the process.
Along with its consistency and colour, generally there is the implication that a mud is somehow of low value, dirty, messy, or otherwise disdained which is unlikely here. Without qualification, however, mud in non-technical contexts involves soil. This further reduces the likelihood of application to wet sand. Muddy has at least two related meanings. It can mean mudded ie covered in mud , but it can also mean like mud dark, thick and opaque.
This latter meaning is just about possible in the context of wet sand. In technical contexts florid analogies tend to get pickled into jargon, so it wouldn't surprise me to see it described as mud in, for example, a civil engineering textbook.
At low tide, the sea recedes to reveal a heavy, saturated sand which has the consistency of mud. Such sand readily coats most surfaces and, once dry, will cake them in fine sand. Sign up to join this community. The best answers are voted up and rise to the top.

Not sure if this applied to this: Like, can I say that my hair became muddy after rolling in that stuff?
Improve this question. Isn't it just called wet sand? It's too bad it isn't technically correct to call it 'slurry'. I like that word. Add a comment. Active Oldest Votes. A little investigation in Google books produced this: She picked up a large handful of the wet sand and threw it at him. Improve this answer.
Community Bot 1. If someone looks through the images, they'll see the same identical image the OP posted. Wet sand can be sticky, thick goo too. It often contains more than just rock particles, and even if not the particles can be small enough that it is sticky and gooey.
And when dried, fine sand, like dried clay mud, can become a hard crust. It's all relative to the size of the particles and perhaps to other, "binding" chemicals. Fine enough particles in suspension gives you viscous, gooey mud. Drew I appreciate the finer distinction, but generally speaking, a sandy beach consists of sand, a pebble beach consists of pebbles, a rocky beach
