Exploring Earth's Dynamic Crust and Natural Disasters

The video explores Earth's structure, including the crust, mantle, and core, and explains how tectonic plates cause earthquakes and volcanoes. It discusses the formation of mountains, subduction zones, and mid-oceanic ridges. The video also covers famous volcanoes, hotspots, and the impact of earthquakes and tsunamis, highlighting the Richter scale and the effects of seismic activity on human structures.

• Silicon and Oxygen

• Iron and Nickel

• Carbon and Hydrogen
