Body of water

Most are naturally occurring and geographical features, but some are artificial. There are types that can be either. For example, most reservoirs are created by engineering dams, but some natural lakes are used as reservoirs. Similarly, most harbors are naturally occurring bays, but some harbors have been created through construction. Bodies of water that are navigable are known as waterways.

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.

Types

This is a list of some common types of bodies of water. Some common geographical features involving water are not bodies of water in their own right, such as geysers, rapids, and waterfalls, and are therefore not included on this list. Some terms, particularly relating to wetlands, refer in part to one or more bodies of water and in part to the land surrounding them, and these have been included on this list.
