as all most of atmospheric air is present near the surface of earth.
The crust is the outermost layer of the Earth's surface. It is solid rock and can be classified into two types: continental crust, which is thicker and less dense, and oceanic crust, which is thinner and more dense.

Earth is more dense.
Oceanic crust is more dense than continental crust.
the less dense layer is on top and the more dense layer is below.
The layer of rock that forms the Earth's outer skin is called the crust. It is divided into two types: the continental crust, which is thicker and less dense, and the oceanic crust, which is thinner and more dense.
The two types of crust that make up the outermost layer of the Earth are continental crust, which is thicker and less dense, and oceanic crust, which is thinner and more dense.
The top layer of the Earth's crust is made up of solid rock called the lithosphere. It includes both continental crust, which is thicker and less dense, and oceanic crust, which is thinner and more dense.
The most dense layer of the atmosphere is the troposphere is the most dense layer because it is at the bottom of the atmosphere. The troposphere is where all our weather happens. It also has the highest air pressure. But more specifically, the earths atmosphere is most dense at the surface.
Because magma is less dense than the surrounding solid rock, it is forced upward toward the surface. When magma reaches the surface and flows from volcanoes, it is called lava.
The least dense layer of the Earth is the crust, particularly the continental crust, which is primarily composed of lighter materials such as silicate minerals. This can be inferred from seismic studies and geological surveys that indicate the composition and density variations of Earth's layers. Additionally, the crust's buoyancy allows it to "float" on the denser mantle beneath, much like how less dense objects float on more dense liquids.
The least dense layer of water is at the surface, where the water is typically warmer and less dense due to factors such as sunlight, wind action, and mixing. This layer is known as the epilimnion, and it floats on top of the more dense layers below.
