Definition: Sand is a mixture of small grains of rock and granular materials which is mainly defined by size, being finer than gravel and coarser than silt. And ranging in size from 0.06 mm to 2 mm.Particles which are larger than 0.0078125 mm but smaller than 0.0625 mm are termed silt.. Sand is made by erosion or broken pebbles and weathering of rocks, which is carried by seas or rivers.

What is capillary action and how is it affected by gravity ...
Capillary action (or capillarity) describes the ability of a liquid to flow against gravity in a narrow space such as a thin tube. This spontaneous rising of a liquid is the outcome of two opposing forces: Cohesion – the attractive forces between similar molecules or atoms, in our case the molecules or atoms of the liquid.

2) Water moves up trees due to capillary action which is important for moving water around. Capillary action is the movement of water within the spaces of a porous material due to adhesion, cohesion forces and surface tension. Capillary action occurs as water is sticky and cohesion force which helps water molecules to stay close together.

The darker the soil, the more capillary water you can find here. The tree 'drinks' the water through its tap roots. In soil, there are millions of vertical channels - pipes - these are called "capillary tubes". Whenever there is a downpour, excess water runs underground through these capillary tubes.

BULKING OF SAND The increase in the volume of sand due to the presence of moisture is known as bulking of sand. This is due to the fact that moisture forms a film of water around the sand particles and this results in an increase in the volume of sand. The extent of bulking depends on the grading of sand.
