Unfiltered streams or lakes that may be contaminated by human or animal wastes are a common source of infection. Outbreaks can occur among campers and hikers who drink untreated water from mountain streams.
Topsoil erosion is most likely to occur on the beds of lakes and streams. This is because the flow of water will pull the soil from the shore into the water.
Jet streams can occur at various altitudes, but the strongest and most well-known jet streams, like the polar jet stream and subtropical jet stream, typically occur at altitudes between 20,000 to 40,000 feet in the upper troposphere. These high-altitude, fast-flowing air currents play a significant role in influencing weather patterns.
Because the rivers and streams cannot handle the amount of rain that has fallen in a given period of time.
The average rainfall on rivers and streams can vary significantly depending on the location and climate of the region. Rainfall typically replenishes river and stream flow, providing a consistent source of water. Areas with higher average rainfall generally have more water flowing in rivers and streams compared to areas with lower average rainfall.
On the outer bank (at the tip of the meander)
Valleys occur between mountains and hills, typically formed by water erosion from rivers and streams over time. They are geographical low-lying areas that are usually longer than they are wide, with varying depths and widths.
