Hi i don't know things about kids is this correct ( see pic )

I think it's one year old

Explanation:

6 months and 6 weeks are both too young and two and a half seems too old but depending on if the kid has siblings or not it's generally around a year old I hope that this helps :)

answer; im thinking (france);

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.
