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.

<u>ANSWER:</u>
Hurricanes so frequent in areas close to the equator because "the ocean water can evaporate more quickly near equator".
<u>EXPLANATION:</u>
- Hurricanes are fast moving wind storms that use heat and most air as their fuel. The air near the 'equator' is warm and moist causing more hurricanes.
- The warm and moist air from the 'ocean surface' rises above and generates an "area of low pressure".
- This causes air from nearby areas to move to the area of low pressure. This new air becomes moist and warm. This warm air when cools forms clouds.
- This cloud systems and winds grows and spins fed by the "water evaporating" from the surface of the ocean. This in turn creates a storm called a hurricane.
Answer:
The sun, our star, will eventually die and become a white dwarf.
Explanation:
When a star dies it goes through a process in which it is called "The lifecycle of a star."
If the sun were to go theough this process and die out, it would eventually reach to the point it can either be a white or black dwarf, but there is more of a possibillity of it becoming a white dwarf than a black dwarf.
