because early on all the earth was molten, and a large part of it is still molten. Lighter elements are less dense than heavier ones and therefore float to the top.
i don't think there is an particular name for it
The top layer of Earth's atmosphere is called the exosphere. It is the outermost layer where the atmosphere transitions into space. The exosphere is very thin and composed mostly of low-density gases.
Earth's crust is part of the Earth's outermost layer, along with the mantle and core. It is composed mainly of solid rock and is where most geological processes, like plate tectonics and volcanic activity, occur. The crust is thinner beneath the ocean than on land and is divided into several large tectonic plates that continuously move and interact with each other.
Another word for the Earth's crust is lithosphere. It is the solid outermost layer of the Earth.
The Earth's interior consists of the crust, mantle, outer core, and inner core. The crust is the outermost layer, followed by the mantle which is composed of the lithosphere and asthenosphere. Beneath the mantle is the outer core, made of liquid iron and nickel, and the inner core, composed of solid iron and nickel.
Initially ? It was the slag that floated to the top as the planet cooled.
the outermost layer of earths atmosphere
The crust.
The inner core is predominately iron, with some nickel, and trace lighter elements, as far as we can deduce from current science.
The crust (the land that we walk on)
No, it is the outermost sphere of the earth.
it would shape like a penis

Earths outermost layer is the crust.Actually, the crust is divided into two parts,Sial and Sima.In that way, actually Sial is the outermost layer of the crust,as it lies above the Sima.

Neptune is the outermost planet, and is farthest from Earth's orbit.
