Answer: A. Comparative advantage, because products can be made more efficiently in the southern United States and Mexico. Operating costs and wages are lower, and the manufactured products are easily transported to major United States markets.
Explanation: Comparative advantage of a location is the ability to produce a good at lower cost than elsewhere. Lower wages, as well as lower operating costs in Mexico and Southern states achieve this comparative advantage by reducing total cost. Their locations are still quite close to the Midwest and North east, in contrast with popular outsourcing locations such as China. It therefore makes sense to relocate factories to these locations.
Answer:
A) sea level drops; land subsides
Explanation:
The sea is the final destination of all streams on land. All streams empty into seas which are the basins that collects all terrestrial materials.
The base level is the lowest level to which a river can erode its channel. The base level is greatly influenced by what happens to a sea.
When a river reaches its base level, erosion ceases. If a river is young and set above its base level, we see a rapid rate of erosion.
A sea, the final basin of depostion of rivers controls the base level to a very large extent. When there is a tectonic movement and a sea subsides. It becomes more deeper and lower. Sea level also falls and materials grades seaward. A river would cut rapidly along its channel and its bed to measure up to the level of the ocean.
Therefore, we see a very rapid rate of erosion of channels when sea level falls and the earth sags downward. This would lead to a lower base level.
When sea level rises and there is a tectonic uplift, rivers erode their channels less and begins to aggrade materials. The base level also rises.
Two ecozones would be different it they had two different climates
