Basically, the higher you get in the atmosphere, the less dense it gets.
It's the exosphere.

The core!
Pumice is a porous rock and slat is not. Pumice floats in water because of the air pockets in the rock. Slate is a layer of rock that is tightly packed, or is very "dense".
The Exosphere.
The core is the most dense layer
It is neither. The densest layer is the inner core. The least dense layer is the crust.
Thermospehere
The highest.
i think the crust
The least dense layer will be found on top of the other layers, as less dense materials tend to float on top of denser materials.
No, the core is not the least dense layer of the Earth; in fact, it is the most dense layer. The Earth's structure consists of the crust, mantle, outer core, and inner core, with the inner and outer cores composed mainly of iron and nickel, making them significantly denser than the mantle and crust. The crust is the least dense layer, primarily composed of lighter silicate minerals.
Earth's outermost layer, the crust, is the least dense layer. It is composed of lighter rocks such as granite and basalt. The crust floats on the denser layers beneath it, including the mantle and the core.
The Earth's Crust.
Thermospehere
No. The troposphere is the lowest, and densest, layer of the atmosphere. The exosphere is the outermost, thinnest layer.
