In the crust, the element helium is at a concentration of 8 parts per billion.
Helium is NOT one of the eight most common elements in Earth's continental crust. The eight most common elements are oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium. Helium is a noble gas and is not as abundant in the Earth's crust.

The Earth's crust can vary in thickness, but on average it is about 5-70 kilometers (3-44 miles) thick. However, it can be much thicker under mountain ranges and thinner under the ocean floor.
The Earth has a radius of 6,360 km. The crust varies in thickness from around 5-70 km with an average value of around 35 km. As such Earth's crust is between approximately 0.07 and 1.1 % of the total thickness of the Earth (average of 0.55 %).

India is not covering some of the earth's crust but part of the earth's crust is part of India
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
