Is it normal that when I make a fist or flex I can see 4 veins bulging out in my arm

Uhhh... sir go see the doctor, or maybe you are just really strong.

the plates spread at mid-ocean ridges (they are divergent plate boundaries) which allows magma to rise through the weakness between the plates. the magma then emerges as lava from the boundary and cools, creating a new crust.
