Question

why are there no locks on the suez canal?

c. few ships transit the canal each year.
d. technological advancements have made them unnecessary

please select the best answer from the choices provided

○ a
○ b
○ c
○ d

Explanation:

Locks are used to adjust water levels between different elevations. The Suez Canal connects the Red Sea and Mediterranean Sea, which have nearly identical sea levels, so locks are unnecessary. Option A is incorrect (salinity doesn’t affect lock need), C is wrong (the canal has high ship traffic), and D is irrelevant (locks aren’t replaced by tech here).

Answer:

B. The elevation of the Red and Mediterranean Seas are about the same.
