Anton has to take insulin for his type 1 diabetes but his sister Maryam has another health issue and takes a pill. Anton knows that insulin is a protein but wants to know why he can't have a pill instead of all those nasty shots. Can you explain it to him?

Direct shots into the blood stream bypasses the stomach, which have digestive enzymes that would break down the protein insulin.

Explanation:

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.
