Body of water
Accumulated water on Earth's surface, natural or artificial.
A body of water is any notable gathering of water found on Earth’s surface. While the phrase commonly brings to mind oceans, seas, and lakes, it also covers smaller accumulations like ponds, wetlands, and—on rare occasions—puddles. Water does not need to be still or enclosed to qualify; rivers, streams, canals, and other moving features where water travels from one location to another are also considered bodies of water. Most of these are natural geographic formations, though some are man-made. Certain types can be either natural or artificial: for instance, most reservoirs are created by damming, but some natural lakes serve as reservoirs, and while most harbors are naturally occurring bays, others are built through construction. Navigable bodies of water are referred to as waterways. Gravity influences bodies of water, often producing tidal effects. Climate change is expected to intensify its impact on water, as seen in rising sea levels, ocean acidification, and flooding, placing increasing pressure on these features. Warmer temperatures melt glaciers and polar ice, raising sea levels and disrupting coastal ecosystems. Freshwater bodies like rivers and lakes face more frequent droughts, reducing water supplies for communities and wildlife. Additionally, ocean acidification—driven by higher carbon dioxide absorption—harms marine ecosystems such as coral reefs. Addressing these challenges requires worldwide cooperation and sustainable water management. **Types** Below is a list of common types of bodies of water. Some water-related geographic features—such as geysers, rapids, and waterfalls—are not themselves bodies of water and are therefore excluded. Certain terms, especially those tied to wetlands, refer partly to a body of water and partly to the surrounding land; these are included.

Lore & Background
Bodies of water are affected by gravity, which is what may create the tidal effects. The impact of climate change on water is likely to intensify as observed through the rising sea levels, water acidification and flooding. This means that climate change has pressure on water bodies. Climate change significantly affects bodies of water through rising temperatures, altered precipitation patterns, and sea-level rise. Warmer temperatures lead to the melting of glaciers and polar ice, contributing to rising sea levels and affecting coastal ecosystems. Freshwater bodies, such as rivers and lakes, are experiencing more frequent droughts, affecting water availability for communities and biodiversity. Moreover, ocean acidification, caused by increased carbon dioxide absorption, threatens marine ecosystems like coral reefs. Collaborative global efforts are needed to mitigate these impacts through sustainable water management practices.
Reader's Guide
Bodies of water are fundamental geographical features that shape ecosystems, human settlement, and climate. They range from vast oceans to small puddles, and include both still and moving water. Their navigable forms, called waterways, have historically enabled trade and transport. Gravity governs their movement, including tides. In the modern era, climate change poses a significant threat: rising temperatures melt ice, raising sea levels and altering coastal areas; altered precipitation causes droughts in freshwater bodies; and ocean acidification from carbon dioxide absorption harms marine life such as coral reefs. These pressures underscore the need for sustainable water management globally. The term also encompasses artificial features like reservoirs and constructed harbors, which may mimic natural forms. Understanding bodies of water is essential for addressing environmental challenges and preserving biodiversity.
Did You Know?
- A body of water does not have to be still or contained; rivers and streams are also considered bodies of water.
- Most bodies of water are naturally occurring, but some are artificial, such as reservoirs created by dams.
- Bodies of water that are navigable are known as waterways.
- Climate change affects bodies of water through rising temperatures, altered precipitation, and sea-level rise.
Frequently Asked Questions
What is a body of water?
A body of water is any substantial collection of water sitting on Earth's surface. While the phrase most commonly brings to mind oceans, seas, and lakes, it also covers smaller features like ponds, wetlands, and even puddles in rare cases.
Do bodies of water have to be still?
No, moving water absolutely qualifies. Rivers, streams, and canals all count as bodies of water even though the water is constantly flowing from one location to another.
What types of water features are included under 'body of water'?
The term spans a wide range, from massive oceans and seas down to small ponds, wetlands, and rarely, puddles. Both naturally formed features and human-made ones such as reservoirs and canals fall under the definition.
What distinguishes a waterway from other bodies of water?
A waterway is specifically a body of water that is navigable, meaning vessels can travel through it. This sets it apart from features like a small pond or a wetland that cannot support boat traffic.
What is the biggest current threat to bodies of water?
Climate change poses the most significant risk, driving rising sea levels, ocean acidification, and increased flooding. These effects are reshaping coastlines and altering the chemistry of both natural and artificial water bodies worldwide.
