Where is most of the freshwater on Earth?

F. lakes: While lakes do contain freshwater, they generally hold a smaller amount compared to other sources. Lakes are formed by various processes, including river inflow, melting glaciers, and precipitation. However, lakes are not the main source of freshwater on Earth, so it is less likely that most of the freshwater is located there.

G. glaciers: Glaciers are massive bodies of ice that form from accumulated snowfall over many years. They store a significant amount of freshwater in the form of ice. In fact, glaciers contain the largest percentage of freshwater on Earth. However, they are not easily accessible since most glaciers are located in polar regions or high mountain ranges. Thus, while glaciers hold a substantial amount of freshwater, they are not the answer to this question.

H. rivers: Rivers play a crucial role in providing freshwater to various regions. They receive water from multiple sources, including rainfall, snowmelt, and underground springs. While rivers can contain a significant volume of freshwater, it is unlikely that they hold the largest amount since rivers are continuously flowing and distributing water to other areas.

J. oceans: Oceans, on the other hand, cover about 70% of the Earth's surface. However, oceans primarily contain saltwater, which is not considered freshwater. Saltwater accounts for around 97% of all water on Earth. While a small percentage of freshwater can be found in the form of rivers, melting icebergs, and precipitation, it is not sufficient to make the oceans the answer to this question.

Based on this analysis, the correct answer would be G. glaciers, as they store the largest percentage of freshwater on Earth. However, it is important to note that this freshwater is not easily accessible for human use due to its location in remote and inaccessible areas.
