One trigger of mass movements occurs when the pores in sediments become filled with water.
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.
Angular sediments have lower porosity compared to rounded sediments because angular grains have irregular shapes that leave less space between them. This results in a more compacted arrangement of grains, reducing the overall porosity of the sediment.
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.
Sands and gravels are porus sediment types that hold a lot of water and allow for high rates of water flow due to the larger pore spaces between the particles. These sediments are known as "porous" or "permeable" due to their ability to store and transmit water easily.
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.

Nuclear pores.
Wax, due to it filling the pores that cause friction will reduce friction.
The nuclear envelope, which surrounds the nucleus, has pores called nuclear pores that control the movement of molecules such as RNA and proteins in and out of the nucleus. These pores help regulate the flow of substances between the nucleus and the cytoplasm.
In resin impregnation, any porous material is made impervious by filling its pores with the resin.
The downward movement of water through soil due to gravity is known as infiltration. Gravity pulls water down through the soil profile, filling pore spaces and reaching deeper layers. This process is essential for replenishing groundwater and providing moisture for plant roots.
The small holes in the nuclear envelope are called nuclear pores. These pores facilitate the movement of molecules such as proteins and RNA between the nucleus and the cytoplasm.
Stomata are tiny pores on the underside of leaves that allow for the movement of gases such as carbon dioxide, oxygen, and water vapor. They open and close to regulate gas exchange and help in photosynthesis and transpiration.
Angular sediments have lower porosity compared to rounded sediments because angular grains have irregular shapes that leave less space between them. This results in a more compacted arrangement of grains, reducing the overall porosity of the sediment.
An impermeable material would have small pores, if any, that are likely unconnected. Small pores limit the movement of substances through the material, and unconnected pores minimize the pathways for substances to traverse.
