Is schist porous
Witrynaa) Permeable rocks can absorb water and impermeable rocks cannot absorb water. To test rock permeability place sandstone, granite, chalk and marble in separate beakers of water. Look closely at the rocks, does anything happen? Draw your results below and use your observations to label whether the rocks are permeable or impermeable.
