Hi all!

Could you help me judge what is ocean and what is sea?
I'm confused what's the defference between 'ocean' and 'sea'?!

Thanks for your help!

An ocean is bigger than a sea. However, we can still refer to traveling across an ocean in a ship or boat as being "at sea".


big - Atlantic Ocean, Pacific Ocean, Indian Ocean

not as big - Caribbean Sea, Caspian Sea, Dead Sea
