When water passes through a rock, it's called infiltration. This process involves water seeping into the ground and moving through the tiny spaces within the rock.
Water moves downward due to gravity after passing through the zone of aeration. It infiltrates through the soil layers until it reaches the water table or a layer of impermeable rock, where it may flow horizontally as groundwater.
A dull grainy looking rock is more likely to let water pass through it compared to a smooth shiny rock. The rough texture of the grainy rock provides more surface area for water to seep into and flow through, while the smooth rock may have a more compact structure that prevents easy passage of water.
Viscosity is the term.
Water that is trapped or stored underground in porous rock layers is called groundwater. This water can be accessed through wells for various uses such as drinking, irrigation, and industrial purposes. Groundwater is an important natural resource that requires proper management and conservation to ensure its sustainability.
Pure salt is obtained from rock salt through a process called evaporation. Rock salt contains impurities and other minerals that are removed when the salt is dissolved in water and then evaporated, leaving behind pure salt crystals. This process helps to separate the salt from any impurities present in the rock salt.
This process is called leaching. Water passing through rock or soil can dissolve minerals and other substances, carrying them away with the moving water.
the impermeable layer
The area underground that rainwater passes through is called the "unsaturated zone" or "vadose zone." This zone lies between the ground surface and the water table, and it allows rainwater to percolate through soil and rock.
An impermeable rock that does not allow water to pass through is called a impermeable rock, such as shale or clay. These rocks have very low porosity and permeability, preventing water from flowing through them.
Permeable soil and rock that allows water to pass through it easily is called "porous" or "permeable" media. This type of material typically has open spaces or pores that enable water to flow through it.
Water can move through Earth's rock and soil layers through a process called infiltration, where it percolates downward due to gravity. It can also move laterally through rock and soil layers via a process called percolation or through fractures and pore spaces in the materials. On the surface, water can flow over the ground as runoff, either flowing into bodies of water or infiltrating back into the ground.
limestone is a permeable rock that allows water to flow through its cracks and pores. As water moves through limestone, it can dissolve the rock, creating caves, sinkholes, and underground rivers. This process is known as karstification.
Infiltration
An impermeable layer of rock that does not allow water to flow through is called an aquiclude or aquitard. These layers restrict the movement of groundwater, creating a barrier for water flow.
permeability
Water stored in soil and rock is called groundwater. It fills the spaces between soil particles or within rock formations, forming aquifers that can be accessed through wells for drinking water and irrigation purposes.
It is younger.
