Final answer:
The material that can be excluded from the list of underground materials in the Ogallala aquifer is A)'mineral'. The aquifer is mainly composed of porous and permeable materials like sand, silt, and gravel, which are capable of storing and transmitting water.
Step-by-step explanation:
The material that can be excluded from the list of underground materials that holds water in the Ogallala aquifer is A. mineral. The Ogallala aquifer, like many others, is primarily composed of geologic materials with a high degree of porosity and permeability such as sand, silt, and gravel which allow water to flow through. Materials represented by the term 'mineral' do not typically signify a porous medium that can hold and transmit water. Instead, minerals, which may be present within an aquifer, generally do not constitute the matrix that stores water.
The Ogallala Aquifer is a crucial source of groundwater in the United States and is an example of a body of water that exists in the pores between particles such as sand and gravel, or in the fissures of rocks. Its capacity to store and transmit water makes it an invaluable resource for drinking and irrigation purposes.
