The deepest sea in the world is the Carribean Sea. While, Mariana trench in the Pacific Ocean is deeper, its part of the ocean, and not a sea.
Challenger deep.
Mariana trench
The deepest known portion of the ocean floor is called the Challenger Deep, located in the Mariana Trench in the western Pacific Ocean. It reaches a depth of about 36,000 feet (10,972 meters).
The Mariana trench is the deepest known oceanic floor - at a maximum known depth of 36,070 feet (+/- 130 feet).
The deepest known portion of the ocean floor is called the Challenger Deep, located in the Mariana Trench in the western Pacific Ocean. It reaches a depth of approximately 36,201 feet (11,034 meters) below sea level.
The deepest parts of the ocean floor are caused by plate tectonic subduction and occur where the sea floor sinks back into the mantle in a subduction zone. These areas are called deep sea trenches and the Challenger Deep in the Mariana Trench in the Pacific is the deepest known point in Earth's oceans.

Challenger Deep in the Mariana Trench is the deepest point in Earth's oceans. The bottom there is 10,924 meters (35,840 feet) below sea level. If Mount Everest, the highest mountain on Earth, were placed at this location it would be covered by over one mile of water.The hadal zone also known as the hadopelagic zoneand trench zone is the name given to the deepest parts of the Ocean. This zone is found from a depth of around 6,000 metres (20,000 ft) to the bottom of the ocean.
The deepest mines and drill holes are typically found in the Earth's crust, specifically in the upper portion known as the lithosphere. These mining operations can extend several kilometers below the surface into the crust.
Oceanic crust
The deepest parts of oceans are dark all the time because natural light does not penetrate to the ocean depths. Little is known about life in the depths of the ocean. More is known about the moon than the depths of the oceans. Water pressure is great, the temperature is constant.
It is known as a trench, which is the lower part of the ocean. The deepest trench is the Marina Trench.
