Plants absrb water through their roots which are in soil; so there must be water under the soil for the plants to survive.
water
Hard-pan clay soil percolates (drains) water the slowest.
Yes, it is called soil erosion. The plant cover reduces soil erosion by water and wind.
Steepness of land means that water can run down at greater speeds taking with it lose top soil. Once this top soil is gone this means the under soil which is easy to erode is eroded easily by rainfall and so gullies form due to the erosion of the soil. Hope this vaguely answered your questions. :)
no soil absorbs more
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
sandy soil drains water
Hard soil does not tire out the joints(thats all i know)
such as a swamp,marsh or bog
More porous soil (sandy soil) facilitate better movement of water under the ground where as clay obstruct it.
Ground water is under ground in the soil and runoff is extra water from when it has rained.
Submerged soil refers to soil that is completely covered or immersed in water. This can occur in wetlands, riverbeds, lakes, or other water bodies. Submerged soil conditions can influence plant growth, nutrient cycling, and microbial activity.
The downward movement of water in soil is known as percolation. This process occurs as water infiltrates the soil surface and moves downwards through pore spaces under the influence of gravity. Percolation helps to transport water, nutrients, and contaminants through the soil profile.
there is air in soil because it is necessary for root growth and also the animals that live under the soil they need oxygen to survive and it determines the porosity of the soil for water to sink in.
HeAlThY?! Unless your talking about plants-then yes(good water, not bad.). All it does is make it wet, as far as I know. ----- Water doesn't make healthy soil (for plants to grow in), however the amount of nutrients in the soil will.
i don't know clay soil lack air and water
