Groundwater flow through rock with high porosity and low permeability would be relatively slow. While high porosity allows for a significant volume of water to be stored, low permeability restricts the movement of that water through the rock. Consequently, even though water can occupy the spaces within the rock, its flow rate will be limited due to the resistance posed by the rock's structure. Therefore, groundwater can take a considerable amount of time to move through such formations.
Permeability affects how quickly groundwater can flow through the soil or rock. Higher permeability allows for faster flow. Slope also influences groundwater flow by controlling the direction and speed of movement. Water will flow more rapidly downhill and may collect in low-lying areas.
An aquifer refers to a body of permeable rock that can contain or transmit groundwater. The factor that determines how much water an aquifer can hold is the composition of its surrounding bedrock.
Groundwater flow through rock can vary significantly depending on the rock type, porosity, and permeability. In highly permeable rocks, like sandstone, groundwater can flow at rates of several meters per day, while in less permeable rocks, such as granite, flow may be very slow, potentially only a few centimeters per year. Overall, the flow rate is influenced by factors like the presence of fractures, the water table, and local geological conditions.
The most important factor in determining the amount of groundwater that can be stored within a rock is its porosity, which refers to the volume of voids or spaces in the rock that can hold water. Additionally, the permeability of the rock, or its ability to transmit water through those voids, also plays a crucial role. Rocks with high porosity and permeability, such as sandstone, can store and transmit more groundwater than those with low values, like granite or shale. Other factors, such as the rock's mineral composition and structure, can also influence groundwater storage capacity.
Groundwater would flow quickly through rocks with high porosity and high permeability. These characteristics allow for water to flow easily through the spaces between the rock particles with minimal obstructions, resulting in fast rates of groundwater movement.

Porosity and permeability of rocks and soil determine how much water can be stored and how easily it can flow through groundwater. Rocks like sandstone and limestone with high porosity and permeability are good at storing and allowing the movement of groundwater. Conversely, impermeable rocks like clay or granite store less water and restrict the flow of groundwater.
Permeability refers to the ability of soil and rocks to allow water to flow through them. Higher permeability allows groundwater to flow more easily, while lower permeability hinders the movement of groundwater. Factors such as grain size, pore size, and connectivity influence the permeability of soil and rocks, impacting how quickly groundwater can flow through them.
Permeability is when water can pass through different types of soil and rocks. Therefore the permeability affects the soil and rocks because if the soil or rock is PERMEABLE then the groundwater can easily flow through it :)
Porosity is the measure of empty spaces or pores in a material like subsoil. A higher porosity allows groundwater to flow more easily through the soil, helping with containment or storage. Coarser materials like sand have higher porosity and permeability than finer materials like clay.

The permeability and porosity of an aquifer is very high, air and pretty much any liquid can pass trough it with ease. Where as shale has very little porosity making it virtually impossible for air or liquid to pass through.
Porosity refers to the amount of pore space in a material, while permeability is a measure of how easily fluids can flow through a material. High porosity indicates more space for fluids to be stored, while high permeability indicates easy flow of fluids through the material.
Porosity refers to the empty spaces or voids in a material, while permeability is the ability of a material to allow fluids to flow through it. Higher porosity means more empty spaces, but that doesn't always translate to good permeability; permeability also depends on the connectivity of these pores.
In order for groundwater to pass easily through the subsoil, the pores must be well-connected and relatively large in size. This facilitates the flow of water through the soil, allowing it to move freely and recharge aquifers. Additionally, a higher porosity and permeability of the subsoil will also contribute to easier movement of groundwater.
