Question

Consider the following water bodies:Lake TanganyikaLake Tonlé SapPatos LagoonThrough how many of them does the equator pass?

Accepted Answer

Correct Answer: D - NoneStep-by-step Solution:The equator is located at 0° latitude and divides the Earth into Northern and Southern Hemispheres. For a water body to be considered crossed by the equator, it must lie exactly on or span across 0° latitude.Water body I - Lake Tanganyika: Located in East Africa, this lake lies entirely in the Southern Hemisphere between approximately 3°S and 8°S latitude. The equator does not pass through it. ✗Water body II - Lake Tonlé Sap: Located in Cambodia in Southeast Asia, this lake lies around 12°N latitude, well north of the equator. ✗Water body III - Patos Lagoon: Located in southern Brazil, this lagoon lies around 30°–32°S latitude, far south of the equator. ✗Thus, none of the given water bodies are crossed by the equator.Why other options are incorrect:Option A: Incorrect. No listed water body lies on the equator.Option B & C: Incorrect. All listed water bodies are clearly away from the equator.Key Concept: Only specific water bodies lie on the equator, such as Lake Victoria (Africa) and parts of the Amazon River basin. Being 'close to the equator' does not qualify as being crossed by it.
