Answer:
The warm water that the ocean conveyor belt carries northwards, releases
heat into the atmosphere, keeping western Europe warm.
Step-by-step explanation:
The Ocean conveyor belt, also known as the Atlantic Meridional Overturning
Circulation (AMOC), "starts" in waters between Greenland and Scotland, more than one thousand miles away, in the north-east Atlantic.
The Atlantic conveyor belt, moves warm water from the tropics, up north to western Europe.
Without it, in winters, the UK, could be 5C colder.
I hope it helps!
