The activity that can tend to lower the water table is Over extraction of groundwater.

Here's why:

1. Overgrazing, human population growth, and soil erosion can all potentially affect the water table, but they do so indirectly.

2. Overgrazing can lead to soil compaction and reduced infiltration rates, which can in turn affect groundwater recharge.

3. Human population growth can increase demand for water and lead to more wells being drilled, which can lower the water table.

4. Soil erosion can reduce the land's ability to hold water, leading to more runoff and less water infiltrating down to recharge the groundwater.

5. However, the over extraction of groundwater directly removes water from the water table, causing it to drop. This can happen when wells are pumped faster than the natural recharge rate of the aquifer.
