Which term describes a water feature that can vanish seasonally?

• A. Disappearing Stream
• B. Intermittent Stream
• C. Perennial River
• D. Small Falls; Small Rapids

Answer: (A)

The idea being tested is how we name streams that do not have water all year and can disappear during dry periods. A water feature that vanishes seasonally is described by a term that explicitly conveys that disappearance.

Among the options, a term that literally captures the image of the water feature disappearing fits best. The other choices describe either a feature that always has water (perennial) or a feature that is simply not always flowing but doesn’t emphasize vanishing, or are more about physical formations than about seasonal presence of water. So the phrase that highlights the seasonal disappearance aligns most directly with the idea of vanishing water, making it the strongest description for this scenario.
