Groundwater Practice Flashcard

Front

What is the saturated zone in groundwater?

Back

The saturated zone is the depth at which the pores in the ground are completely filled with water.

Front

What does permeability mean in the context of groundwater?

Back

Permeability refers to the ability of soil or sediment to allow water to flow down through it.

Front

How does rainfall affect the water table level?

Back

The water table level is higher when it rains.

Front

What is infiltration in the water cycle?

Back

Infiltration is the process by which water on the ground surface enters the soil.

Front

Define porosity in relation to soil and sediments.

Back

Porosity is the amount of spaces between sediments or soil particles.

Front

What is the water table?

Back

The water table is the upper surface of the saturated zone, below which the ground is saturated with water.

Front

How does soil texture affect permeability?

Back

Soil texture affects permeability; sandy soils have high permeability, while clay soils have low permeability.

Front

What role does vegetation play in groundwater recharge?

Back

Vegetation helps in groundwater recharge by facilitating infiltration and reducing surface runoff.

Front

What is the difference between the saturated zone and the unsaturated zone?

Back

The saturated zone is where all pores are filled with water, while the unsaturated zone contains both air and water in the pores.

Front

What factors influence the rate of infiltration?

Back

Factors influencing infiltration include soil type, vegetation cover, land slope, and moisture content.
