Oceanography: SSC CGL Geography
Oceanography has seven questions in the SSC CGL Tier I bank: two from the 2023 shifts, three from the 2024 shifts and two from the 2025 shifts. Each asks one fact about tides, salt or coral reefs, so this chapter is a single page of short tables. Learn why a tide comes twice a day and how salt layers the sea, and the rest follows.
The handout has every subtopic, worked example, formula and trap with answers shown. The formula sheet is the chapter’s formulas and traps alone, on one page.
