Question 8 of 13intermediate🧠 RememberShort Answer2 marks

List out the deepest trenches of various oceans.

Correct Answer

The deepest trenches (oceanic deeps) are distributed across various oceans as follows:

A total of 57 deeps have been explored so far. Out of these, 32 deeps are found in the Pacific Ocean, making it the ocean with the maximum number of trenches. The Atlantic Ocean has 19 deeps, while the Indian Ocean has 6 deeps.

These trenches are relatively steep-sided, narrow basins that occur at the bases of continental slopes and along island arcs.

Explanation

The textbook context provides specific numerical data about the distribution of oceanic deeps/trenches across different oceans. It states that 57 deeps have been explored in total, with 32 in the Pacific Ocean, 19 in the Atlantic Ocean, and 6 in the Indian Ocean. The context does not provide specific names of individual trenches like Mariana Trench or Puerto Rico Trench, so the answer is limited to the distribution count provided in the text.

Solution Steps

  1. Step 1: Identify the section on 'Oceanic Deeps or Trenches' in the context.

  2. Step 2: Extract the numerical data about deeps in each ocean.

  3. Step 3: Present the distribution: 32 in Pacific, 19 in Atlantic, 6 in Indian Ocean.
