Each year, earthworms move deep into soil during fall and winter and return toward spring and summer. The likely stimulis for this behavioral response are relative humidity & temperature. Since the nematode breathes via the skin, the mucus coating may become dry & the organism would die if exposed to extreme cold & dryness.
As Na and Cl make up much of the dissolved common salts found in the ocean waters, the element in the earth's crust can be easily be dissolved in the rain and river and get carried away from the runoff of the river.
Infiltration is process by which water on the ground enters the soil. The porosity of the soil particles on land water determine the infiltration capacity and thus are a major source of dissolved sediments in water bodies.
Also, rainfall influences this rate of sediment flows in water all the organic and inorganic matter in the soil is mainly composed and collected from the rain and discharge rate of the soil. Weathering produces mass wasting and erosion of the landforms from the above and thus indirectly related to the dissolved content.
