Is the core the densest layer of earth?
The Troposphere is the lowermost portion of Earth’s atmosphere. It is the densest layer of the atmosphere and contains approximately 75 percent of the mass of the atmosphere and almost all the water vapor and aerosol. The troposphere extends from the Earth’s surface up to the tropopause where the stratosphere begins.
The inner core is the deepest layer on Earth. It is also made up of iron and nickel but the pressure is so high that it is no longer liquid. The temperatures in the inner core are as hot as the…
The least dense layer is the exosphere which is the outermost layer of the atmosphere. In my science book it says, “it is least dense because it is farthest from the earth, whose gravitation force decreases in accordance with the inverse-square law.
The Earth’s inner core is a solid mass, composed of sulfur, iron, oxygen, and nickel. As the deepest layer, it has the greatest density of the four layers that make up Earth.

The crust, the outermost layer, is rigid and very thin compared with the other two. The mantle, which contains more iron, magnesium, and calcium than the crust, is hotter and denser because temperature and pressure inside the Earth increase with depth.
Oceanic crust is denser because it generally melts to a higher fraction than continental crust. When rocks melt to 20–30% like they do at mid-ocean ridges, the result is more dense than when rocks melt to form continental plates, which is typically 1–5%.
The core is the hottest, densest part of the Earth. Although the inner core is mostly NiFe, the iron catastrophe also drove heavy siderophile elements to the center of the Earth.
