Introduction / Context:
Salinity comparisons appear frequently in physical geography. While many small enclosed lakes are hypersaline, among the named seas in common GK, the Dead Sea (a salt lake bordered by Jordan and Israel/Palestine) is famous for its extremely high salinity that allows people to float effortlessly.
Given Data / Assumptions:
- We compare regional seas: Red Sea, Dead Sea, Arabian Sea, Mediterranean Sea.
- Interpret “most salty sea” as the highest average salinity among options.
- Accept the well-established relative rankings used in GK texts.
Concept / Approach:
The Dead Sea’s salinity typically exceeds 30% by mass (varies by depth and season), far above oceanic averages (~3.5%) and above the Red Sea (~4% to >4% in places) or the Mediterranean (~3.8%). The Arabian Sea is essentially open ocean with typical marine salinity values. Thus, the Dead Sea is the most saline among the listed choices.
Step-by-Step Solution:
List each sea’s approximate salinity: Dead Sea ≫ Red Sea > Mediterranean ≈ Arabian Sea (open ocean).Select the extreme case: Dead Sea.
Verification / Alternative check:
Visual evidence of effortless floating and salt crusts at the Dead Sea shoreline is widely documented; scientific surveys confirm the extreme salinity compared to typical seas.
Why Other Options Are Wrong:
Red Sea / Mediterranean Sea: High for open seas but far below the Dead Sea's hypersalinity.Arabian Sea: Typical ocean salinity; not extreme.
Common Pitfalls:
Assuming “sea” excludes salt lakes; in GK usage, the Dead Sea is consistently accepted as the saltiest among commonly cited seas/lakes.
Final Answer:
Dead Sea
