Explain the concept with the help of the following points: 

(a) Origin of Egypt: Egypt was originally known as ‘Kemet’. Egypt got this name because of ‘ the black soil that was deposited by the Nile floods. Later Egypt came to be known as ‘Hewat-ka- Pta’. It means the temple of God. The Greeks changed it to ‘Egyptus’. In the course of time, it was changed to ‘Egypt’. The Arabic name of Egypt is ‘Misra’.

(b) Yellow River: Yellow River’ is the English translation of the Chinese name ‘Huang He’. The yellow silt brought by her has earned her this name. ‘River’ and ‘Mother’ are her other names. These names indicate her extraordinary place in Chinese culture. The name ‘River’ indicates that she is considered to be the only river of importance. The fact that she is considered to be the mother of the Chinese culture is obvious in the name, ‘Mother’.

(c) Fluted core technique: The blades used for Mesolithic tools were removed from Siliceous stones by the technique known as ‘Fluted Core Technique’. These blades are as tiny as our fingernails. So they are called ‘Microliths’. The Mesolithic people used wooden arrows fixed with microlithic arrowheads.
