Erosion and Deposition

The podcast discusses erosion and deposition, using the story of Pablo the Pebble to illustrate these natural processes. Erosion occurs when materials like soil or rocks are removed by wind or water, while deposition is when these sediments are dropped off in a different location, changing the Earth's surface over time. The podcast encourages listeners to observe the effects of rain and wind to see examples of erosion and deposition. The podcast concludes by thanking the listeners and promising another episode in the future. Hello everyone, today we will be talking about erosion and deposition. What will we be talking about? Erosion and deposition. First, let us listen to the story about Pablo the Pebble. Pablo is a pebble who lives in a little patch of grass near a river. Pablo is not well behaved, so he is always grounded. He is getting really bored of being in the same place all the time and he often dreams of escaping to the far away land across the river. One morning, Pablo wakes up and notices that the wind is blowing a little bit harder than normal. He hears thunder and sees lightning flashing across the sky. Pretty soon, the wind really started to gush and big, fat raindrops started to fall. All of a sudden, Pablo is lifted off the ground by strong wind and whisked into the fast flowing river. The water carries him for several minutes until he washes up on the opposite bank. Pablo is in a whole new world. He has just experienced natural processes called erosion and deposition. Let's talk a little about what erosion and deposition are. Erosion is when material like soil or rocks are removed by wind or water. All of these materials are called sediments. Deposition now is when these sediments are deposited or drop off in a different location. This process changes the way the surface of the earth looks over time. So, erosion and deposition are constantly happening. After all, wind and water can easily cause materials to move to different places. So, what I want you to do for me, next time it rains, find a patch of dirt and watch what happens when the drop hits. Does the dirt look exactly as it did before or was it moved in some way? And when it's windy outside, can you see all the dust blowing around in the air? Yes, these are just some examples of erosion and deposition. Thank you so much for listening. You will hear from me next time in another podcast.
