The Mariana Trench is the deepest part of the ocean. It was made by the powerful forces that shape our planet. This deep trench was formed through subduction. This means the dense Pacific plate goes under the smaller Mariana plate.
As the Pacific plate sinks into the Earth’s mantle, it makes a deep, narrow trench. This is how the Mariana Trench was created.
The Mariana Trench is where two big tectonic plates meet – the Pacific and the Mariana plates. The Pacific plate is older and heavier. It is being pushed under the lighter Mariana plate.
This makes a deep ocean trench. The process of subduction also causes volcanic arcs and lots of earthquakes in this area.
Learning about how tectonic plates work and their role in making deep ocean trenches like the Mariana Trench is important. It helps us understand the geological processes that have shaped our planet over time.
The Challenger Deep is the lowest spot on Earth, found in the Mariana Trench. It goes down about 36,070 feet (10,994 meters). This deep spot was made by powerful forces under the sea over time.
The Challenger Deep is at 11°22.4′N 142°35.5′E. It has three deep basins, each about 6 to 10 km long, 2 km wide, and over 10,850 m deep. Scientists now say it’s the deepest spot on Earth, at 10,935 ± 6 m (35,876 ± 20 ft).
Explorers and scientists love the Challenger Deep, leading to many amazing trips there. In 1960, Jacques Piccard and Don Walsh were the first to reach the bottom in the Trieste bathyscaphe. Later, in 2012 and 2019, James Cameron and Victor Vescovo made new records by diving there too.
