Question
estimate that about 90% of earths freshwater supply comes from the
statement best describes the process that makes this phenomenon
ocean water evaporates from the surface, leaving the salt behind.
ocean currents drive weather conditions, creating more precipitation.
phytoplankton and other ocean organisms release water vapor into the air.
precipitation falls on the ocean surface, diluting the salt and making it drinkable.
clear all
Earth's freshwater (including that stored in glaciers, ice caps, and groundwater) primarily originates from the hydrologic cycle. When ocean water evaporates, the salt (a non-volatile component) remains in the ocean, leaving only pure water vapor. This vapor then condenses and falls as precipitation, which replenishes freshwater sources, accounting for the large portion of Earth's freshwater supply. The other options do not describe the core process that generates freshwater from ocean sources.
