The Evil Eroders
Texto del Guión Gráfico
- Wet Willy loved to erode the land by groundwater erosion, which created a large cave or underground cavern and many sinkholes. Groundwater is water held underground in the soil or crevices of rock. Inside the cave, stalagmites or mounds rising from the cave floor were created. Stalactites hung from the ceiling and were formed of calcium salts deposited by dripping water.
- Wet Willy left by runoff and drained away from the surface of the land.
- My work here is done! I must be off to my lair!
- Down south from where Wet Willy was creating trouble, an evil glacial eroder, named Icy Ivy, was eroding Antarctica using glaciers and her ability to make it snow and ice. Two specific kinds of glaciers she used were alpine glaciers that are formed in mountainous areas, and continental glaciers, which are huge masses of ice that can spread across entire continents.
- These glaciers helped Icy Ivy erode Antarctica due to their weight and their ability to move across Earth's surface. When Ivy eroded the land, she formed moraines which are collections of rocks and minerals that have been deposited by a glacier.
- I'm causing so much trouble and I love it!
- She also formed kettles, big holes or openings in a floodwater plain, and eskers, long ridges of gravel and other sediment. Outwash, which is the material deposited by meltwater streams in front of a glacier developed.
- U-shaped valleys developed when she eroded a river valley and cirques, bowl-shaped depressions where glacial ice cuts back into the mountain walls, were composed.
