- woah! i just felt the ground shaking under me , i think that was a small earthquake.
- yes, you are correct it was a small earthquake. An earthquake is caused by a sudden slip on a fault. ... When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.
- thank you for the clarification , but how do you know so much about earthquakes?
- you are welcome! well i know that much because i am a science teacher.
- interesting! can you please tell me more about earthquakes?
- i am really happy you liked this topic, its really interesting . so do you want to know how the earthquakes can affect the biogeochemical cycles?
- i would really like to know about it! but can you please explain what are the biogeochemical cycles?
- of course i will explain it for you, In ecology and Earth science, a biogeochemical cycle is a pathway by which a chemical substance is turned over or moves through the biotic and the abiotic compartments of Earth.
- By triggering landslides, fracturing rock, changing permeability, and influencing hydrologic pathways, earthquakes alter geochemical processes of the river systems, so large earthquakes may directly link tectonic activity and chemical fluxes.
- well that was easier than i thought! you can now explain the effect of earthquakes on it.
- thank you teacher i really appreciate it!
- you are always welcome!
