The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
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).
The earth's crust is not stress
Platinum is considered a rare metal, with an abundance of around 5 parts per billion in the Earth's crust. It is found in relatively low concentrations compared to other metals like iron or aluminum.

its the percentage in mass !
Neodymium is relatively abundant in the Earth's crust, with an average concentration of about 38 parts per million. It is considered a relatively common rare-earth element compared to others in the lanthanide series.
Platinum is considered a rare element on Earth, with an estimated abundance of about 0.005 parts per million in the Earth's crust. It is mostly found in association with other metals such as nickel and copper ores. Platinum is also found in small quantities in meteorites and certain types of rocks.
The Earths crust is approximately 650 km deep.
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.
Protactinium is so scarce that the abundance in the Earth crust was not determined.
