Study Notes
Waterbodies
- Water covers nearly three-fourths of Earth's surface, hence it's called the "Blue Planet".
- A waterbody is any collection of water on Earth's surface.
- Waterbodies vary in size.
- Waterbodies can have either fresh water or saline water.
- Fresh water is the purest form of natural water; it does not contain any salts (e.g., rainwater).
Types of Waterbodies
- Lake: A large body of still water surrounded by land. Lakes can be freshwater or saltwater. Lake Superior is the largest freshwater lake in the world. Also, ponds are smaller bodies of water, typically freshwater and shallower than lakes.
- River: A large natural course of running water that flows from a higher elevation to a lower one, usually emptying into a larger body of water (like a sea, lake, or ocean). A river's starting point is called the source; the place where it empties is called the mouth. Tributaries are smaller streams that flow into the river.
- River Tributaries: Smaller streams that feed into larger rivers, contributing to the river's flow.
- Waterfall: A waterfall occurs when a river or other body of water flows over a steep, rocky edge, creating a spectacular sight. Niagara Falls, Victoria Falls, and Angel Falls are examples of famous waterfalls.
- Sea: A large body of saline water on the Earth's surface. Seas are often partially enclosed by land. Examples include the Arabian Sea and the Mediterranean Sea, and the Dead Sea, which is famous for its high salinity. Seas are part of the oceans.
- Ocean: The largest and deepest waterbodies on Earth, generally containing salty water. There are five major oceans: Pacific, Atlantic, Arctic, Indian, and Southern (Antarctic) Oceans. Oceans are the largest bodies of water.
Salinity of Water Bodies
- Saltwater (saline) water is not suitable for all living things.
- Minerals and salts from various rocks are carried by rivers into the seas and oceans, increasing salinity. This creates salty water.
- The Dead Sea is known as the saltiest sea. It has high salinity due to high concentration of minerals in the water. 97% of Earth's water is in oceans and seas, not suitable for drinking due to high salt content.
Additional Information
- Oceans and seas contain various aquatic creatures, plants, and seaweed.
- The Indian Ocean is named after the country of India.
- Waterbodies are crucial for various purposes, including drinking, recreation, and transportation.
- 97% of the Earth's water is found in the oceans and seas, but it's not suitable for drinking due to high salt content.
- The Ganga is an important river in India, with the Yamuna as a major tributary.
