Water contained in pores of soil or rock is groundwater..
Pores are tiny openings between particles of rock or soil that can contain air or water. These pores allow for the movement of gases and liquids through the material.
The upper layer of saturated rock and soil is called the water table. It represents the boundary between the unsaturated zone above, where pores contain both air and water, and the saturated zone below, where all pores are filled with water.
Water that soaks into the ground and collects in pores in soil and rock becomes groundwater. Groundwater is water that has infiltrated the soil and rocks below the Earth's surface, filling the spaces between particles or within cracks and cavities. It is an important water source for wells and springs.
Soil pores can be filled with air, water, and organic matter. Air fills the larger pores, while water occupies the smaller pores. Organic matter such as roots, fungi, and bacteria also contribute to filling soil pores.
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.
Below the water table is the saturated zone, where the pores in the rock or soil are filled with water. This is where groundwater is stored and flows, providing water for wells and springs. The unsaturated zone above the water table contains both air and water in the pores.
Compacted soil absorbs less water when wet, as the pores in the soil become filled with water and limit additional water flow into the soil. When the soil is dry, the pores are more open, allowing for better water absorption.
It is the water contained in the soil that evaporates.
Ground water saturation refers to the condition in which the pores, cracks, and spaces in the soil or rock underground are filled with water. It is a measure of how much water a given volume of soil or rock can hold. Saturation levels can vary depending on factors such as precipitation, geology, and human activities.
Groundwater is water found beneath the Earth's surface in spaces between soil and rock particles. It is stored in the pores of soil, sediment, and rock formations and can be accessed through wells. Groundwater plays a crucial role in providing drinking water for many communities and sustaining ecosystems.
The upper level of groundwater is typically referred to as the water table. This is the boundary between the unsaturated zone above, where water fills the pores of the soil and rock only partially, and the saturated zone below, where all available pores are filled with water.
The tiny spaces between particles of soil are called pores. These pores can be filled with air or water, determining the soil's ability to hold water and support plant growth.
