Sand doesn't have micro pore space, but only macro pore space.
rock
The smaller the grain, the less pore space there is to allow fluid movement. The larger the particle grains, the greater the movement due to the overall increase in pore space between particles.
yes, The rocks are larger, creating a higher amount of space in between each individual rock.
pore space is important because animals and plants need it
clay
having pore size 0.3 micron
It's possible that there is no pore space in a diamond stone, because its lattice density indicates that its atoms are more closely together than the atoms of any other known substance.
Porosity or pore space
It's possible that there is no pore space in a diamond stone, because its lattice density indicates that its atoms are more closely together than the atoms of any other known substance.
Gabbro has little pore space. This is because of the interlocking crystals that make up the rock, allowing almost no water through it.
porosity
because because plants compete for it
