How do rivers form (surface and groundwater flow)

In this video, we will look into why water flows in rivers long after the rain has stopped. Where does the water come from? We will learn that rivers are fed from surface runoff, as water flows over the surface during, or shortly after it rains, but also through their beds, by groundwater which infiltrates through the soil and is stored in the pores of rocks in large underground reservoirs called aquifers. Finally, we will see that some water also comes from the melting of snow and ice high up in the mountains. #brightblue #rivers #watercycle
