the soil that allows water to pass through very slowly is clay
Because gravel has gaps that the water can travel through and clay is less likely to although water can still travel through it but slower
Soil color has absolutely no influence on the rate at which water can pass through it. Red soils are red because a microscopically thin layer of an iron oxide coats the mineral soil particles. If the Fe oxide coating is on sand particles, water will pass through it quickly. If the Fe oxide coating is on silt or clay particles, water will pass through it more slowly, unless the soil has favorable structure. Take a sample of the red soil and wet it. If you can mold it and work it with your fingers to any extent, it has some clay in it. If it can be molded like modeling clay, it has a lot of clay in it.
Clay soil is said to hold the most water. This is because the soil's particles are so small and there are numerous small soil spaces. Water moves slowly through. So there is great water retention.
The sandy soils let the water pass through but the clay soils hold the water
the soil that allows water to pass through very slowly is clay
Clay has very small pore spaces
Because the pores, or air spaces, between particles are much smaller in clay than in silt, loam, or sand. The water simply can't get through very quickly.

Impermeable means water can't get through it. For example, clay is impermeable substance (because water can't seep through it), but chalk is permeable (because water can drip through it slowly) Sometimes it also applies to places which you can't get into, for example, an 'impermeable fortress' would be difficult to get into.
Water passes through clay slower because clay has greater density than regular dirt so it is a lot more compact.
clay isn`t coarse enough but pebbles are

because sand has small grains and allows water to travel through it. Clay has smaller grains than sand and doesn't allow water to travel through it quickly.
No. Clay particles are very small and tend to attract other clay particles to from a matrix. Permeability refers to the ability of a gas or liquid to flow through a material. Because clay forms a tight matrix, gas and liquids flow very slowly through clay. Loose sand has high permeability
