This answer is: Hide Comment (1 ...Mudcracks form when mud is dewatered, shrinks, and leaves a crack. This tells you that the mud was saturated with water and then exposed to air. Mudcracks curl upwards, so they can be used as geopetal structures.Sediment is the product of mechanical and chemical weathering and of erosion by wind, water, and ice. Biological activity also plays a role. Sediment may be deposited in the form of sand building up as a dune, or a beach as pebbles piling up in a stream, or shelves an organic matter accumulating on the ocean floor.
Naturally forming mudcracks start as wet, muddy sediment dries up and contracts. A strain is developed because the top layer shrinks while the material below stays the same size. When this strain becomes large enough, channel cracks form in the dried-up surface to relieve the strain.The intrusion of I1 or I2 is the youngest event. Without more information, we cannot know which igneous rock is youngest. A fault (F) breaks three layers of sedimentary rock (S).

Property owners can take proactive steps to ...Mudcracks form when a shallow body of water (e.g., a tidal flat or pond or even a puddle), into which muddy sediments have been deposited, dries up and cracks. This happens because the clay in the upper mud layer tends to shrink on drying, and so it cracks because it occupies less space when it is dry.
Bedding Planes. Figure 7.4.1 7.4. 1: Horizontal strata in southern Utah. The most basic sedimentary structure is bedding planes, the planes that separate the layers or strata in sedimentary and some volcanic rocks. Visible in exposed outcroppings, each bedding plane indicates a change in sediment deposition conditions. Geologically, in a terrestrial environment, graded bedding is also referred to as normal bedding. It is a systematic change in nature, wherein, from the base to the top, a progressive upward gradation of fragments, sediments, or grains are coarsened into finer compositions.
