because elasticity of clay is very small, so when reaction of wall acts on the clay, clay cannot withheld the force and it deforms
The clay boat (like a steel ship) displaces its own weight in the water. So, as long as the sides of the clay boat (or steel ship) is above the water level, it will float. A solid piece of clay will (like a stone) sink immediately.
You could built a boat of clay. Provided the clay has been fired and will not dissolve in water. Provided that once placed in water, it is able to displace its gross weight and still have ample freeboard to prevent water coming inboard. Whether the clay walls of the vessel is strong enough to withstand the considerable forces of the oceans is another matter!
Because if you were too get clay lump and the floating clay shape because it's more dense
relative density and gravity
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.
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
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.
clay isn`t coarse enough but pebbles are
Water passes through clay slower because clay has greater density than regular dirt so it is a lot more compact.
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
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.
because it is dense
