The main way surface waters become groundwater is when "Water flows through the unsaturated zone and into the saturated zone". This process is known as infiltration. Here's a step-by-step explanation:

1. Precipitation: Rain or snow falls to the ground.

2. Surface Runoff: Some of this water flows over the land surface, into rivers, lakes, and oceans.

3. Infiltration: Some of the water seeps into the ground. This is the water that has the potential to become groundwater.

4. Unsaturated Zone: The water first enters an area called the unsaturated zone, where air fills most of the spaces between the soil or rock, but water can still move through.

5. Saturated Zone: As water continues to seep down, it eventually reaches an area where all the spaces in the soil and rock are filled with water. This is called the saturated zone, or the water table.

6. Groundwater: Once in the saturated zone, the water is considered groundwater.

So, the correct answer to your question is "Water flows through the unsaturated zone and into the saturated zone".
