What else can I help you with?
Porosity is the amount of pore space in soils. Permeability is the ability of water to pass through the soil. Why do some soils have high porosity but low permeability?
Some soils may have high porosity due to a large number of interconnected pore spaces, but low permeability because the pores are small and not well connected. This restricts the movement of water through the soil, despite the high porosity.
Why does some earth materials hold more water than others?
Earth materials vary in their capacity to hold water due to differences in their porosity and permeability. Porosity refers to the amount of pore space within a material, while permeability describes how easily water can flow through it. Materials with high porosity and permeability, such as sand and gravel, can hold more water compared to materials with low porosity and permeability, such as clay and bedrock.
What is the permeability and porosity of the soil in Antarctica?
Well, in Antarctica, the soil is called Permafrost. It is very silty/sandy-like.The porosity is very low, the soil cannot hold very much water. And as you may know, if soil has low porosity, then it must have high permeability.Now I'm not really going to get into details, but that is the main idea. If you are looking for more of a detailed explanation, then I will link a website you can get some more information on.Here it is: http://en.wikipedia.org/wiki/Permafrost
What makes some soils more permeable than others?
The permeability of soil is influenced by factors such as soil texture, structure, compaction, and organic matter content. Soils with larger pore spaces, such as sandy soils, tend to be more permeable than soils with smaller pore spaces, like clay soils. Compacted soils have reduced permeability due to decreased pore spaces for water to flow through. Organic matter can improve soil structure and increase permeability by creating aggregates that allow for better water movement.
why does water pass through some soils faster than others?
Water passes through some soils faster than others due to differences in porosity and permeability. Soils with larger pores and well-connected pore spaces allow water to flow more easily, while soils with small pores and less connectivity impede water movement. Factors such as soil composition, structure, and compaction can influence these properties and affect how quickly water can pass through the soil.

Is basalt permeable?
There are 2 types of permeability- Porosity and Perviousness Granite and basalt are both pervious Granite has low porosity, but basalt can be both porous or non-porous. It depends on its rate of cooling.
What are the phyical properties of sand?
Sand has several physical properties. Some of the most important are porosity, mineral composition, grain size, grain shape, and permeability.
Some ponds are designed to increase the amount of water seeping into the ground. These types of ponds will fail to work properly in -?
soils with low permeability
Why are some rocks more permeable than others?
Some rocks are more permeable than others due to differences in their porosity and pore connectivity. Rocks with higher porosity and well-connected pores have greater permeability, allowing fluids to flow through more easily. Factors such as grain size, sorting, and cementation also play a role in determining the permeability of rocks.
Is sand and soil the same?
Sand content is part of many different native "soils", but they are not exactly the same thing. Loam soil - the best kind for growing things - is made up of fairly equal proportions of sand, silt, clay and organic matter. Some soils are high in clay (called "heavy" soils). Some soils are high in sand content - the soil in my own yard for example. So in a sentence: Sand is a component of most soils - it is not "soil" by itself.
How permeable is basalt?
Basalt is considered to have low to moderate permeability, meaning it allows some water to flow through it, but at a slower rate compared to more porous rocks. This can vary depending on factors such as the porosity and fractures within the basalt.
When some substances can pass across them but others can not what are biological membranes said to have?
selective permeability or semi-permeability
