Which of the following factors does NOT influence the level of the water table?

• A. Type of soil and rock
• B. Amount of precipitation
• C. Air temperature in the stratosphere
• D. Rate of groundwater withdrawal

Answer: (C)

Verified step by step guidance

1. Understand the concept of the water table: The water table is the upper surface of the zone of saturation, where soil and rock are fully saturated with water. It is influenced by various environmental and human factors.
2. Analyze the factors listed: The type of soil and rock affects the permeability and porosity, which determine how water moves and accumulates underground. The amount of precipitation directly impacts the recharge of groundwater, raising or lowering the water table. The rate of groundwater withdrawal influences how quickly water is removed from the aquifer, potentially lowering the water table.
3. Consider the factor 'Air temperature in the stratosphere': The stratosphere is a layer of the atmosphere far above the Earth's surface. Its temperature does not directly affect groundwater or the water table, as it is unrelated to processes like precipitation, soil permeability, or groundwater withdrawal.
4. Identify the correct answer: Since 'Air temperature in the stratosphere' does not have a direct connection to the water table, it is the factor that does NOT influence the level of the water table.
5. Conclude the reasoning: The other factors listed (type of soil and rock, amount of precipitation, and rate of groundwater withdrawal) are all directly related to the dynamics of the water table, while air temperature in the stratosphere is not relevant to this context.
