Pete used “sediments” that were all the same shape and size in this demonstration. How would varying the size of the “sediments” affect the porosity (assuming the total volume of “sediment” remains the same)? Write in complete sentences using good grammar.
The varying size will affect the porosity such that the bigger sediments will lead to increased porosity while smaller sediments will lead to decreased porosity.
What is Porosity?This is also known as void fraction and is a measure of the void spaces in a material or substance.
Smaller sediments will fill the space leaving very little space for water to flow through while bigger sediments don't fill it up which is why water can flow through easily.
