Answer:
C.The Great Migration westward during the war led to too many people growing too many crops too quickly
Explanation:
The WW I contributed to the development of the Dust Bowl because their was high rate of movement of farmers westward of the Great plain for farming which expose the land without protective measures taking ahead.
During this period, government policies on land, the regional weather change, brings about massive movement towards the plain there by making in experience farmers to plant and massively based on demand for wheat which in return expose the floor surface to dust bowl based on lands that have been plowed and exposed . The dust bowl came and started to blow away the already exposed land which do not have deep rooted grass again to grasp onto the soil and brought about eroded soil.
NOTE: The Dust Bowl is the period of massive dust storms that destroy the ecosystem and resulted into drought in the 1930's.
Initially, you might want to look at how little America does produce- what could we even offer to a nation that produces almost everything. Another reason why Americans may be at a disadvantage with trading with China is due to our HUGE trade deficit- we owe so much money. On top of that, taxes on things being traded can be used against nations, if we traded with China and they raised the tax on imports than it could impact us very negatively.
It is because of subduction<span>: oceanic crust tends to get colder and denser with age as it spreads off the mid-ocean ridges. It gets so dense, that it sinks in the upper </span><span>mantle </span><span>(subduction). This is like a giant recycling system for oceanic lithosphere! Because continental crust is lighter than oceanic crust, continental crust cannot subduct. We therefore still have some very </span>old continental rocks<span> at the surface of the Earth.</span>
Some countries did not like the countries we were with an alliance with, so they would attack them and we would attack the country who did it, and so on.
