The abundance of neodymium in the earths crust is approx. 40 ppm.
Lithium is the 25th most abundant element in Earth's crust, with an average concentration of about 20 parts per million (ppm). This makes it relatively rare compared to other elements like silicon and oxygen.
crust
Silicates make up about 90% of Earth's crust. These minerals are composed of silicon and oxygen, along with other elements like aluminum, iron, calcium, and magnesium. Silicate minerals are the building blocks of most rocks on Earth's surface.
Another word for Earth's outer surface is "crust."
The crust, more specifically the lithosphere.
blah
its the percentage in mass !
Neodymium is a natural element and a rare-earth metal that can be found in the Earth's crust. It is not man-made.
The Earths crust is approximately 650 km deep.
Protactinium is so scarce that the abundance in the Earth crust was not determined.
Lithium is the 25th most abundant element in Earth's crust, with an average concentration of about 20 parts per million (ppm). This makes it relatively rare compared to other elements like silicon and oxygen.
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.

Quartz
The crust is the layer of the Earth that contains granite and basalt in the greatest abundance. These rocks are commonly found in the continental crust (granite) and oceanic crust (basalt).
