Yes, oceans, lakes, and rivers are all bodies of water on Earth. They are part of the hydrosphere, which is the collective mass of all water found on the planet, including the water in underground aquifers, ice caps, glaciers, and atmospheric moisture. Each type of body has distinct characteristics:
Oceans: These are vast bodies of saltwater that cover about 71% of the Earth's surface. They are the largest water bodies on Earth and play a pivotal role in climate regulation and marine life support.
Lakes: Found both in low-lying areas and high elevations, lakes are typically smaller than oceans and can be freshwater or saltwater, depending on their source of water and geographical location. Lakes can be formed by geological processes, human activity, or glacial movement.
Rivers: These are bodies of flowing water that start in high elevations and run downhill towards lower elevations, often draining into lakes or oceans. Rivers are critical for transportation, irrigation, and supplying aquatic ecosystems.

Each of these different forms of water plays a unique and essential role in the Earth’s ecosystems and human activities.
