rivers

Rivers are natural waterways that flow from higher elevations, such as mountains, toward lower areas, often culminating in oceans, lakes, or other bodies of water. They are formed by the collection of rainwater, melting snow, or groundwater that accumulates and moves across the land due to gravity. Rivers shape landscapes through erosion, transport sediments, and support ecosystems by providing habitat for plants, animals, and humans. They play crucial roles in agriculture, industry, and daily life, serving as sources of freshwater and pathways for transportation. Their flow and characteristics vary depending on geography, climate, and underlying geology.
