Answer:
Poor planning, and disease
Explanation:
The obstacles that the French faced while attempting to build a canal across Panama were diseases and poor planning. The French dealt with constant outbreaks of malaria and yellow fever, which slowed construction and caused the deaths of thousands of workers. The French also did not take into consideration the geographical differences between the Suez Canal region and the Panama region. The French had succeeded in building a canal at sea level in Egypt, and they mistakenly thought a similar design would work in Panama. However, the difference in the Atlantic and Pacific Ocean sea levels, as well as the difference in elevation of the Panamanian terrain, prevented them from building a sea-level canal. The United States knew about these two problems when they undertook the project. They took preventative measures by reducing the disease-spreading mosquito population and using a canal-lock system to overcome the elevation obstacle in Panama.
The landforms in the interior of the continents and at their margins mostly differ because of the difference in geological activity.
Explanation:
The landforms that are found in the interior of the continents tend to be old. They also are mostly consisted of sedimentary and metamorphic rocks. In general the erosion is much more evident and dominant, thus the landforms also are with lower elevations when compared with the ones on the edges. This is due to the lack of geological activity as the interiors of the continents tend to be far away from the plate boundaries.
The landforms on the edges of the continents tend to be younger in general. The reason for that are the subduction zones and intense geological activity. The intense geological activity is due to the close proximity of the plate boundaries. The landforms tend to be higher in general, and volcanic arcs are also a common sight.
