Then fluid can travel through the rock, and the rock is said to be "permeable".
A rock containing well-connected pores is typically called a porous rock. These connected pores allow for the movement and storage of fluids such as water or oil within the rock. Examples of porous rocks include sandstone and limestone.

A structure called the nuclear pore complex is formed where the two layers of the nuclear membrane fuse. These pores allow the transport of molecules such as proteins and RNA in and out of the nucleus.

sorry about spelling - porous rocks
No, gravity does not directly cause groundwater to move through connected pores in the Earth's crust. Groundwater flow is primarily driven by differences in pressure gradients and the topography of the land surface. Gravity is involved in influencing the downward movement of water through the soil and rock layers, but the actual flow of groundwater is governed by hydraulic gradients and permeability of the subsurface materials.
in pores or holes in the soil and the underlying rock layers
Because the pores within the shales are poorly connected or even not connected and on the other side the pores within the sandstones are much connected which allow the fluid to flow.that's why the flow rate of sandstone is greater than that of shale.

The endoplasmic reticulum is physically connected to the nucleus through membrane components known as nuclear pores. These pores allow for communication and transport of molecules between the nucleus and the endoplasmic reticulum.
