Consider the following statements:
Where fold mountains runs parallel and close to the coast, continental shelf is narrow or absent
The average depth for continental shelf is 100 metres.
Submarine canyons are mostly found in continental slope.
The submarine flat topped mountains are called guyots.
Which of the statements given above are correct?
-
1, 2. 3 and 4
-
1, 2 and 4
-
1, 3 and 4
-
2 and 3
C
Correct answer
Explanation
Statement 1 is correct - fold mountains running parallel to coastlines typically have narrow or absent continental shelves (like the Andes). Statement 2 is incorrect - continental shelf depth ranges from 0-200m, averaging 130m, not exactly 100m. Statement 3 is correct - submarine canyons are indeed common on continental slopes. Statement 4 is correct - guyots are flat-topped seamounts (submarine mountains).
