How does enhanced fetch affect wave formation?

The correct answer highlights that enhanced fetch allows waves to grow larger and more defined. Fetch is defined as the distance over water that wind blows in a uniform direction. When there is a longer fetch, winds can act on the water surface for a greater distance. This energy transfer from the wind to the surface water can significantly increase the size and height of the waves that form.

As wind blows over this extended distance, it generates more energy, which accumulates in the waves, resulting in not only larger waves but also waves that are better shaped and more organized. Well-defined waves are generally a result of sustained wind acting over a long fetch, allowing for greater wave development and less interference from other factors that could disrupt wave formation.

The other options do not accurately reflect the relationship between fetch and wave formation. Smaller waves would not benefit from a strong fetch, and stating that fetch has no impact overlooks the fundamental dynamics of how wind generates waves. Additionally, wind is critical in the wave formation process; without it, there cannot be waves generated in the first place.
