1. what was the opportunity cost of military, space, and heavy industry production for
the producers of consumer goods?

Magma forms by partial melting of upper mantle and crust. partial melt means that only a fraction of the available material forms a melt, and that the remainder stays solid. the partial melt rises because of its lower density and ascends through he crust. this is so conclusive mean the answer would be magma igneous rocks or balistic magma.

Earthquake waves that vibrate from side to side and up and down only through solids are known as "seismic waves."hope my answer has you : )

Idk bro sorry  lava is hotter then magma but im  not sure about it alll

The answer is c, i, iii, and iv. this is because farming and mining deal with harvesting raw materials, construction work falls under manufacturing, and piloting a plane is a service. ii is wrong because making bread is using  raw materials to produce goods, which would fall under the secondary sector, not primary.
