We are wrapping up our Hawaii Expedition as well. Please post any question you have ready. Good Morning Mr. Trust. We are ready to pose some questions of you. We will be asking some good scientific questions hopefully.
Waterfalls form in a variety of ways.
In Yosemite, glaciers played a major role. In larger valleys with larger rivers, the glaciers were also larger. In smaller valleys with smaller rivers, the glaciers were much smaller. Larger glaciers are much more effective at doing erosion, whereas smaller glaciers are quite ineffective. So, the valleys with smaller glaciers aren't cut down nearly as much as those with larger glaciers.
