such as a swamp,marsh or bog
It's called SILT
Plants absrb water through their roots which are in soil; so there must be water under the soil for the plants to survive.
Soil texture (particle size), organic matter content, compaction, soil structure, and soil depth are key factors that affect soil water retention. Soil with smaller particles like clay retains more water than sandy soil due to higher surface area, while organic matter helps improve water retention capacity. Compaction and poor soil structure can reduce water infiltration and storage capacity, while shallow soils may have limited capacity to hold water.
I need to know about soil improvement with respect to soil stress such as adding sand cement or similar higher stress material to get better bearing capacity.
The area under the surface where rocks and soil are saturated with water is called the water table. It represents the boundary between the unsaturated zone above and the saturated zone below, where all spaces between particles are filled with water. The water table fluctuates in response to factors such as rainfall, evaporation, and groundwater extraction.
Fibrous roots are shallow and spread out horizontally in the soil to absorb water and nutrients efficiently. They do not typically grow deep into the soil compared to taproots.
Clayey soil will absorb more water than sandy soil. This is because clayey soil has smaller particles with more surface area, allowing it to retain water more effectively than sandy soil, which has larger particles with less surface area.

Shallow-rooted plants can help raise the water table by facilitating the infiltration of water into the soil through their root systems. When it rains, these plants absorb water but also allow excess water to percolate deeper into the ground. Their transpiration process creates a vacuum that pulls more water into the soil, promoting groundwater recharge. Additionally, the organic matter from decaying roots improves soil structure, enhancing its ability to retain moisture.
When the soil becomes thick on the hillside, rain water tends to wash it down the hill. The soil then accumulates in the river valleys and help to form the delta at the mouth of major rivers.
you can get gas under water, usually encased in the soil of the water, carbon dioxide and methane
Because it is not connected to the sea water. It is stored as under ground water
