Name the 7 oceans of world in Hindi?

There are actually not seven oceans in the world. The concept of seven oceans is more of a historical and literary idea.

However, here are the major water bodies often referred to as "oceans" in Hindi:

1. हिंद महासागर (Hind Mahasagar): Indian Ocean

2. प्रशांत महासागर (Prasant Mahasagar): Pacific Ocean

3. अटलांटिक महासागर (Atalantic Mahasagar): Atlantic Ocean

4. आर्कटिक महासागर (Arktik Mahasagar): Arctic Ocean

5. अंटार्कटिक महासागर (Antartik Mahasagar): Southern Ocean (also known as the Antarctic Ocean)

These are the five main ocean basins that are widely recognized.

Let me know if you have any other questions.
