Explanation:
Detailed explanation-1: -Lower Mantle: The lower mantle lies between 660-2, 891 km (410-1, 796 miles) in depth. Temperatures in this region of the planet can reach over 4, 000 °C (7, 230 °F) at the boundary with the core, vastly exceeding the melting points of mantle rocks.
Detailed explanation-2: -Cold, salty water sinks to the bottom of the ocean. Water gets colder with depth because cold, salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface.
