Erosion: Part I
Storyboard Text
- Slide: 1
- We made it, hon! Are you excited for are beach day?
- I'm so excited, Mommy! But I'm confused...the beach looks so different than when I was little. It looks like there's...less of it.

- Well...it looks like there's less beach because of something called erosion, which is when something gradually wears away, in this case our beloved beach. Storms, or hurricanes (like the big one last year!) contribute to erosion. Basically, the high-speed winds from the hurricane hit the beach and carry sand/rock/dirt particles away and move them to a different location. Overtime, especially when we're getting multiple hurricanes per year, more and more sand particles will be carried away and transported to another location and the beach will look smaller and smaller. This is generally how erosion works. Weathering--which is the decomposition of materials (like rocks)--makes the beach more at-risk of erosion. These hurricanes cause all those beautiful rocks over there to become weathered.

- Oh no that's scary. But at least we can still enjoy what's left of the beach and this whole "erosion" thing doesn't really affect us.

- Oh hon, no, I'm afraid this does affect all of us humans. Remember when Grandma's house got flooded and she had to live with us for a few months? Well, her house got flooded because of erosion. When the hurricane hit, there was already less "beach" due to erosion overtime, so the water from the ocean didn't have as much of a barrier to get through before it hit our town. And as you know, Grandma's house is way closer to the beach than our house!
