Rivers

• A delta is a landform that forms at the mouth of a river, where it flows into an ocean, sea, lake, or reservoir, and deposits sediment that is carried by the river.
• Hydraulic action refers to the high pressure applied by swiftly moving water that causes rock particles to tumble and wear away.
• Abrasion refers to the scraping and grinding of rock particles against each other due to water flow.
• Attrition breaks rock particles into smaller pieces through friction.
• A confluence is the point where two or more rivers or streams meet.
• A meandering river is a river with a winding course formed by erosion and deposition of sediment.
• Attrition occurs when rocks collide with one another during transport, causing them to break apart and become smaller.
• Solution involves the dissolving of minerals from rocks due to chemical reactions between the water and the rocks.
• Tributary - A stream or river that empties its waters into another larger body of water such as a river or lake
• Human activities such as damming, pollution, and deforestation have significant impacts on river health and sustainability.
• Meander - A bend or curve in a river's channel caused by erosion on the outside bank and deposition on the inside bank
• Oxbow Lake - An oval-shaped lake created when a meander becomes cut off from the main river channel
• River delta - The area where a river enters an ocean, sea, or large lake, characterized by sediment deposits forming landforms like spits, bars, and lobes
• Riverbank - The area along the edge of a river where vegetation grows
• Erosion - The process by which soil particles are removed from an area through the action of wind, rain, ice, or other natural forces
• Stream - A small body of flowing water, typically smaller than a river but larger than a creek
• Tributary - A stream that flows into another stream or river
• Waterfall - A vertical drop of water over a rocky outcrop or cliff
• Watershed - The boundary between two drainage basins, separating areas that flow to different rivers or bodies of water.
• youthful stage (upper) is when a river's gradient is steep, the speed is fast-flowing, and the channel is wide. It causes erosion. Examples of landforms include V-shaped valleys, interlocking spurs and waterfalls
