Glossary Activity Geo Part 2
Text z Príbehu
- Phew! Much cooler here! Erosion is the wearing down, transportation and deposition of material by water, wind and ice.
- I wonder how this cave got here...
- Ohh, yes! I know! The cave was created by a giant sea monster who kept trying to make a crack in this big rock and eventually over hundreds of millions of years, he made an enormous opening which is now a cave!
- In other words, this geomorphologist (who investigates how landforms are formed on the Earth) is saying that the cave was created due to erosion; water slowly seeped into the cracks and pores in the limestone and eventually dissolved the rock and created this cave!
- Tectonics is the processes within the mantle which build up the various features on the Earth's crust, for example this volcano! I'm not too sure if it's a dormant or extinct volcano...
- UH OH! Seems like this is a dormant volcano! I don't think I have to explain what that means!
- RUN!!!
- That was close! So the last word for today is weathering, which means, the physical or chemical breakdown of materials into smaller materials.
- Rivers cause weathering, as moving water in rivers cause rocks to rubtogether.
- So I hope you learnt something new today. Until next time!
