Scientists believe that Earth has four layers (crust, mantle, outer core, inner core) based on seismic waves produced by earthquakes and volcanic activity. These waves travel through the Earth at different speeds and behave differently depending on the properties of the material they travel through, allowing scientists to infer the presence of distinct layers with varying densities and compositions. This model helps explain Earth's structure and how it influences geological processes.

How many layers do a human stomach have?

The human stomach has four layers. These layers are the mucosa, submucosa, muscularis, and serosa. Each layer serves a specific function in the digestion and movement of food within the stomach.


How scientists believe the earths four layers were formed?

when this earth cooled from being hot, all the Iron and Nickle get concentrated inside earth forming inner two layers Inner solid core and outer liquid core. Then with the passage of time earth solidifies gradually and mantle solidifies and now at this stage our crust the outer most part of earth look like its final product.
