The atmosphere
If S waves only pass through some of Earth's layers, it would indicate that those layers are likely to be solid and not capable of transmitting shear waves. This information can be used to infer that the layers where S waves cannot propagate are likely to be composed of molten material or fluids that do not support shear wave transmission.
The air in a mine is typically more dense than the air on the Earth's surface. This is because the air in a mine is generally cooler, leading to higher air density due to cooler temperatures causing the air molecules to be packed closer together.
If you were to dig into the Earth, you would encounter the three major layers in this order: crust, mantle, and core. The crust is the outermost layer, followed by the mantle, which is hotter and more dense. Finally, at the center of the Earth is the core, which is divided into the liquid outer core and the solid inner core.
You would draw the line at the base of the lithosphere, which is the boundary between the lithosphere and the asthenosphere. This boundary is located around 100-200 kilometers below the Earth's surface and marks the point where the rigid lithosphere transitions to the more ductile asthenosphere.
In disturbed sediments without layers, the relative age of the sediments would be unknown.
Instead of all the liquids mixing together, they form separate layers like a rainbow. They go in order with most dense on the bottom, and least dense on the top. When you do this experiment, you can use food coloring to differentiate the different liquids.
The crust is the least dense portion of the solid Earth because it is the thinnest layer.
When heated, gases typically expand and become less dense. So, a gas would be least dense when heated.
it sucks
The least dense layer of the earth is the Crust , the mantle is second densest , whereas the core is the most dense layer of the earth
The least dense liquid would be found at the top.
Liquids with different densities in a container will layer based on their density, with the most dense liquid at the bottom and the least dense at the top. The liquids will not mix together but form distinct layers based on their respective densities.

The egg is like a model of the layers of the Earth. (see layers of the ... The egg shell will represent the thin outer layer of the Earth called the crust.
it cant
The planet Saturn is the least dense of all the planets.I think this is actually about the " four spheres" on Earth.The four "spheres" of the Earth's surface can be described as:atmosphere, biosphere, hydrosphere, and lithosphere.The least dense is the atmosphere.
