Fresh water habitats are classified as either lentic systems, which are the stillwaters including ponds, lakes, swamps and mires; lotic which are running-water systems; or groundwaters which flow in rocks and aquifers.
Jul 28, 2024 · Much of Earth's fresh water is trapped in glaciers and polar ice caps (figure 13.1.c 13.1. c), and this water is inconveniently located, mostly in Antarctica and Greenland. Shallow groundwater (water located below the Earth's surface) is the largest reservoir of usable fresh water.
The water (or hydrologic) cycle (that was covered in Chapter 3.2) shows the movement of water through different reservoirs, which include oceans, atmosphere, glaciers, groundwater, lakes, rivers, and biosphere. Solar energy and gravity drive the motion of water in the water cycle.

Sep 25, 2024 · Where is Fresh Water? Fresh water starts out as water vapor that has evaporated from the surface of oceans, lakes, and other bodies of water. When this vapor rises, it leaves salts and other contaminants behind and becomes “fresh.”

- Freshwaters and Humans. Freshwaters (i.e., lakes, rivers, wetlands, and groundwaters) are pivotal for both nature and human well-being. People depend on freshwater as a resource as well as on freshwaters as valuable ecosystems.
- Freshwaters: Coupled Meta-Ecosystems. Freshwaters are unique ecosystems because they (i) form linear or mosaic landscape elements, embedded into the terrestrial matrix; (ii) are located at the topographically lowest points in the landscape and, therefore, integrate the various processes and pressures of the surrounding matrix; (iii) may rapidly expand and contract in area and/or volume; and (iv) are “open systems”, which are vertically, laterally, and longitudinally connected to belowground, atmospheric, terrestrial, and marine systems.
- Global Distribution of Freshwater Systems. Although freshwaters are a very common feature of the land surface, we still lack accurate estimations of the global distribution of the various freshwater types (rivers, lakes and ponds, wetlands, groundwaters, and artificial water bodies).
- Freshwaters: Hot Spots of Biodiversity. Freshwaters are centres of global biodiversity, similar to tropical rainforests and coral reefs. Although freshwaters (excluding wetlands) cover less than 1% of the Earth’s surface, they contain about 10% of all animal species, one-third of all vertebrate species, and 40% of all fish species globally (Table 16.1).
Jun 8, 2018 · Freshwater on the land surface is a vital part of the water cycle for everyday human life. On the landscape, freshwater is stored in rivers, lakes, reservoirs, creeks, and streams. Most of the water people use everyday comes from these sources of water on the land surface.
