Answer:
Oceans = > 97 percent of Earth's water.
Glaciers = > 70% of Earth's freshwater
River = > Powered by gravity
Groundwater = > 100 times more water than all rivers and lakes
97% of the water on Earth is not drinkable as it is salt-water in oceans.
Of the 3% that is freshwater, Glaciers make up about 70% which means that we don't have access to a significant amount of freshwater either.
Of the available freshwater to us, groundwater comprises 98% which enables it to be 100 times more than all rivers and lakes.
Rivers are powered by gravity in that they flow from areas of higher elevation to areas of lower elevation as gravity pulls it downwards.

Answer:
I think it is population geography
“Climatic conditions help to shape various ecosystems and habitats around the globe. A particular climate can be a boon to one species and a devastation to another. As the climate changes, species and ecosystems respond by adapting, migrating, or reducing their population. Gradual shifts in the climate are easier to adapt to than abrupt swings, and this is certainly true for humans as well as other species. Studies of Earth's climatic history indicate that climates have changed in the past and resulted in dramatic shifts in ecosystems. The most recent geological period the Holocene (about last 10,000 years), however, has been unusually stable.”
