Sedimentary Rock Formation
Kuvakäsikirjoitus Teksti
- Frederick was a rock who lived on El Capitan in Yosemite National Park. He was very happy there but he craved adventure
- What's going on?!
- One night it rained very hard, this rain broke up poor Frederick by weathering
- Frederick's broken pieces were carried down a river where erosion broke him up even more
- Ahhh! Help me!
- I'm in little pieces :(
- The river carried Frederick to the sea where the process of deposition settled out his broken pieces
- Over millions of years the weight of new layers of sediment squeezed Frederick's pieces tightly together this process is called compaction
- It is getting very claustrophobic in here
- While the compaction was going on, minerals glued Frederick's pieces to the other particles of sediment in layers. Frederick was now a sedimentary rock!
- The End!
