WEATHERING
Storyboard Text
- I'm a rock, hello. I'm smaller than most people here, so I'm not very well liked. Additionally, I experience weathering. which occasionally can be a pain. I sometimes get even smaller as I time passes!
- Physical, biological, and chemical weathering are three different types that all have an impact on me. Rocks deteriorate through a process called physical weathering that modifies their chemical composition. If there is abrasion, ice wedging, roots growing in cracks, animals burrowing in stones, and a temperature change, physical weathering will occur. Trees send down roots through joints or cracks in the rock in search of moisture. As the tree develops, the rock is gradually broken apart. Many animals eat their way into rocks, just like these Piddock shells, to protect themselves by either scraping the rock's grains away or secreting acid to dissolve it. The ice is dissolving into sediments behind me, as you can see.
- Mineral alteration in a rock is referred to as chemical weathering. Most frequently, oxidation, hydrolysis, and carbonation are the culprits behind chemical weathering. On the rocks behind me, rust is developing; this process is known as oxidation.
