None, since a square is a two dimensional shape.
That depends on how thin you spread it. If it's a meter thick, it only covers one square meter. If it's a centimeter thick, it covers a hundred square meters.
Density of loose soil is about 1200 kg/m3 1 cubic meter of soil may weigh more than this if compacted or moist.
soil weighs 1600 kg/ cubic meter
You cannot use a measure of area to calculate its weight.You need a third dimension to first calculate the volume and then convert to weight by knowing the density of the soil.If you have a depth of one meter there is one cubic meter and soil has a density of about 1,3 so your cubic meter of soil weighs 1,3 tonnes.
Earthworms enrich the soil with their waste, providing it with much needed nutrients.
The answer depends on where the soil is, and also on how deep you dig into the square metre area.
That depends on how thin you spread it. If it's a meter thick, it only covers one square meter. If it's a centimeter thick, it covers a hundred square meters.
Earthworms make soil healthy by going underground
Because earthworms eat just about every other organism in the soil.
they fertilize the soil
No, but the earthworms in the soil reproduces.
I think it is about 14.2 milllion
Density of loose soil is about 1200 kg/m3 1 cubic meter of soil may weigh more than this if compacted or moist.
The answer is that earthworms help to build soil and fertilize
soil weighs 1600 kg/ cubic meter
Earthworms live all over the world, there is no specific place they live in.
