because the sand is very softer than a clay
Dry clay can be recycled by putting it in water. This will remoisten the clay and allow it to be kneaded and molded. Once clay has been fired it can no longer be recycled. Fired clay can be soaked a long time and will not dissolve.
you take a piece of clay and use it on a bucket of water, voila, soft clay.
stick clay with WATER
olla
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
Water stored in clay jar become cold because of water moves from the inner surface to the outer surface of the clay jar.
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.
Clay has very small pore spaces
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
clay because it has the smallest particles thus making it difficult for water to travel through.
I would think clay because it has more density water would go right through sand :)
Water is held between soil particles by capillary forces. Coarse sandy soils have large pores and water drains through it quickly. Clay soils have smaller pores and are able to hold more water.
No, dry clay is not safe to put in a fish tank because clay is made up of chemicals and when you put that substance of chemicals into water the chemicals diffuse (spread) and that could harm the fish. But if you don't have any fish in the tank its OK to put hard clay in it.
