Mud is a liquid or semiliquid mixture of water and any combination of soils (loam, silt and clay). It usually forms after rain or near water. Ancient mud deposits harden in geological time, forming sedimentary rocks such as shale or mudstone (usually called pyrite). When the geological sediment of mud is formed in the estuary, the resulting layer is called Gulf mud.

In the construction industry, slurry is a kind of semi fluid material, which can be used for coating, sealing or adhesion materials. According to the composition of mud, it can be called by many different names, including mud, mortar, plaster, plaster and concrete.

Historically, mud, corncobs, adobe, clay and many other names have been synonymous with a mixture of subsoil and water, possibly with the addition of stone, gravel, straw, lime and / or asphalt. This material is used in various ways to build walls, floors and even roofs. For thousands of years, in most parts of the world, mud brick or thorn and daub, rammed earth or ear stick technology have been widely used to build walls and cover the surface with mud plaster.

The mud can be made into bricks (also known as Adobe) by mixing the mud with water, putting the mixture into the mold, and then drying it in the open air. Straw is sometimes used as an adhesive in bricks because it adds a support grid. When a brick breaks, the straw redistributes the force to the entire brick, reducing the chance of breaking. Such buildings must generally be protected from groundwater pollution by construction on the basis of masonry, burnt bricks, rocks or debris, and must be protected from the effects of wind and rain in humid climates, usually by deep roof overhangs. In extremely dry climates, well drained flat roofs can be protected with a prepared (agitated) and properly maintained dry slurry coating, as the slurry will swell when wet, making it more waterproof and therefore feasible. Pueblo Indians usually use Adobe Adobe mud brick to build houses and other necessary structures.

Mud can provide homes for a variety of animals, including worms, frogs, snails, clam Lam and crawfish. Other animals, such as hippos, pigs, rhinos, buffaloes and elephants, are immersed in mud to cool and protect themselves from the sun. The submerged soil may be home to various insect larvae.

There are a lot of worries about foods with poor taste, such as "earthy taste". Kava tea is often described in this way because it is bitter, brown and contains sediment.

There are also children's "mud" formulas, usually chocolate or corn starch based sludge, which are more used for visual appeal than actual taste. This candy mud never really contains real mud.

Mud jam is a popular cross-country racing sport in Canada and the United States. Its purpose is to make the vehicle drive through mud pit or fixed length track. The winner depends on the distance through the pit. However, if there are several vehicles that can travel the entire length, the time required to pass through the maintenance station will determine the winner.

Mud running is a popular activity involving mud. Participants ran three to 10 miles as they crawled through mud and swamps and struggled with other obstacles.
