Are soil and dirt one and the same, and is it possible to run out of either? Hypothetically speaking, is there a set amount of soil on Earth? How does more soil get generated?
In: 145
Soil is just dirt with organic material in it.
Dirt is just some composition of clay, silt, and sand.
Clay is just any hydrophilic, self attracting, mineral which has a particulate size .002mm or smaller.(Typically Silica)
Silt is any mineral particulate with a particulate size .002mm to .05mm.
Sand is any mineral with a particulate size .05mm to 2mm
