Groundwater Porosity & Permeability

Front

What is groundwater?

Back

Water that is found underground in aquifers, filling the spaces between rocks and soil.

Front

Define porosity.

Back

The measure of the storage space available in an aquifer, expressed as a percentage of the total volume.

Front

What is permeability?

Back

The ability of a material to allow fluids to pass through it, often measured in terms of the speed of flow.

Front

How does grain size affect permeability?

Back

Larger grain sizes generally allow water to flow faster through the soil, increasing permeability.

Front

What is the relationship between soil type and permeability?

Back

Different soil types have varying permeability; sandy soils are more permeable than clay soils.

Front

What does it mean if a material is impermeable?

Back

It means that the material does not allow water to pass through it.

Front

Give an example of a permeable material.

Back

Sand is an example of a permeable material that allows water to flow through easily.

Front

What is an aquifer?

Back

A geological formation that can store and transmit water, often tapped for drinking water.

Front

What is the significance of groundwater?

Back

Groundwater is a crucial resource for drinking water, irrigation, and maintaining ecosystems.

Front

How does water flow through permeable materials compared to impermeable materials?

Back

Water flows faster through permeable materials than through impermeable materials.
