It is neither. The densest layer is the inner core. The least dense layer is the crust.
When heated, gases typically expand and become less dense. So, a gas would be least dense when heated.
From most dense at the core to least dense proceeding outward.
The crust is the least dense. The inner core is the most dense. So from the middle outwards the layers get less and less dense
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
It is neither. The densest layer is the inner core. The least dense layer is the crust.
No. In fact it is the most dense planet. The least dense is Saturn.
One could say that the atmosphere is the least dense, but of the surface the crust is the least dense.
Helium is the least dense element at normal conditions.
'Least' is a comparison word. Compared to iron and lead yes cotton is least dense. Compares to oxygen gas and hydrogen gas, no it is not least dense.
When heated, gases typically expand and become less dense. So, a gas would be least dense when heated.
Saturn is the least dense planet in our solar system.
The exosphere is the least dense part of the earth's atmosphere.
(most dense to least dense) gold, mercury, water, oxygen
Saturn is the least dense of the gas giants, even out of all of the planets in our solar system. Its average density is around 0.7 g/cc (less than water).
From most dense at the core to least dense proceeding outward.
Callisto is composed of rock and ice and is the least dense of the Galilean moons.
