Final answer:
The hydrologic cycle is another term for the water cycle, which is a biogeochemical cycle where water is continuously moved and transformed on Earth.
Step-by-step explanation:
The term hydrologic cycle is synonymous with the water cycle. This cycle outlines the constant movement and transformation of water as it flows through various states - liquid, solid (ice), and vapor - and locations on Earth, including the atmosphere, oceans, rivers, lakes, glaciers, soil, and the biosphere.
The water cycle is an essential biogeochemical cycle that enables water to be recycled on, above, and below Earth's surface. Solar energy and gravity are the driving forces behind the processes of evaporation, condensation, precipitation, infiltration, runoff, and subsurface flow, all of which are integral to the water cycle.
The correct answer to the student's question is option 2) water cycle.
