The Impact of Water on Earth's Landscape

Ms. Laura introduces the effects of Earth's hydrosphere on the geosphere, explaining the concepts of hydrosphere and geosphere. A scenario about beach changes is discussed, with students offering explanations for the observed changes. The video explores natural bridge formations caused by wind and water erosion. Students are tasked with drawing their favorite natural bridge from a video and submitting it for grading. The video concludes with a summary and farewell.
