The mariana trench

The Mariana Trench is the deepest part of the ocean. It is located in the Pacific Ocean. In 1960, two explorers, Jacques Piccard and Don Walsh, became the first people to reach the bottom of the trench. They used a special submarine called the Trieste to make this historic journey.

The trip was very dangerous because the trench is almost 36,000 feet deep. The pressure at that depth is extremely high, and it could crush most submarines. However, the Trieste was designed to handle the pressure, and it took nearly five hours for them to reach the bottom.

When Piccard and Walsh got to the bottom, they could not see much because it was very dark. They stayed there for about 20 minutes, but they saw some signs of life, such as small fish. It was surprising to find life in such deep, harsh conditions.

In 2012, filmmaker James Cameron made another trip to the bottom of the Mariana Trench. He went alone in a special submarine and spent more time exploring. These journeys helped scientists learn more about the deep ocean, which is still mostly unknown.
