The definition of the term in geology and paleontology is slightly different from its use in soil science. In geology and paleontology, a paleosol is a former soil preserved by burial underneath either sediments (alluvium or loess) or volcanic deposits (lava flows or volcanic ash), which in the case of older deposits have lithified into rock.
Patterned Ground – Patterned ground occurs where stones form circles, polygons and stripes. Local topography affects which of these are expressed. A process called frost heaving is responsible for these features. Solifluction lobes – Solifluction lobes are formed when waterlogged soil slips down a slope due to gravity, forming U-shaped lobes.
Waterlogged: Preservation of plant material can also occur when it is deposited in permanently wet, anoxic conditions, because the absence of oxygen prohibits microbial activity. This mode of preservation can occur in deep archaeological features, such as wells, and in lakebed or riverbed sediments adjacent to settlements.
Experts say the tectonic shifts from the quake pushed the ground up 13 feet in some areas and moved it sideways by more than 3 feet. The ocean floor is now higher.
Bogs occur where the water at the ground surface is acidic and low in nutrients. A bog usually is found at a freshwater soft spongy ground that is made up of decayed plant matter which is known as peat. They are generally found in cooler northern climates and are formed in poorly draining lake basins. [6]

a tract of low-lying ground in which water collects; a piece of wet spongy ground; a marsh or bog. The meaning 'forested wetland' is according to OED more or less obsolete, and was typical of American English during the colonization era. Marsh, on the other hand, is defined as: 1. (a tract of) low-lying land, often flooded in wet weather and ...
