RAS question
The Dead Sea is:
Correct answer: (C) The lowest point on Earth's surface (about 430 m below sea level).
The Dead Sea is the lowest point on Earth's surface, lying about 430 m below sea level.
Explanation
The Dead Sea is best identified as the lowest point on Earth's surface. It lies between Israel, Jordan, and Palestine and about 430 m below sea level; NASA Science describes the Dead Sea as Earth's lowest point, at 418 m below sea level. Its name is not evidence that it is a true sea: it is actually a salt lake. Its extreme salinity, about 34%, is the reason fish cannot survive there. So the key geographical fact tested here is relief, not size, depth, or freshwater status.
Why the other options are wrong
- (A) The Dead Sea is not the largest sea; it is identified instead by its exceptionally low elevation and is a salt lake rather than a true sea.
- (B) It is not a freshwater lake because it is extremely saline, with salinity around 34%.
- (D) It is not being tested as the deepest lake; the defining fact here is that its surface lies about 430 m below sea level, making it the lowest point on Earth's surface.
Concept
This tests world physical geography, especially exceptional landforms and water bodies. Such facts recur in RAS because they link map-based location, relief and basic geomorphology in a single question.
