The lithosphere layer is above the asthenosphere, a layer that presents the rocks in a more pasty state, due to the high temperatures present inside the planet. The meeting zone between the lithosphere and the asthenosphere has an isotherm, that is, a constant temperature, which is approximately 1,200ºC. Thus, everything above this point of contact has sufficient temperatures to make the rocks remain rigid.
Prime numbers are numbers that are only divisible by 1 and themselves. So, to tell if a number is prime, look at its factors.
19:
1 x 19
29:
1 x 29
39:
1 x 39
3 x 13
So, because 39 has more than one set of factors, it's NOT a prime number.
