The Mariana Trench
The Mariana Trench is the deepest and one of the most mysterious places on Earth. It lies in the western Pacific Ocean, near the Mariana Islands. The deepest part is known as the Challenger Deep, which is about 11,000 metres deep. This is much deeper than the height of Qomolangma, the world’s highest mountain.
Life in the Mariana Trench is very difficult. Sunlight cannot reach the dark bottom, so no plants can grow there. The water is extremely cold, and the water pressure is so high that it can easily break most machines. However, some special and strange sea animals still live here. They have to be strong enough to live in cold water and high pressure.
For scientists, the Mariana Trench is very important. By studying it, they can learn more about deep-sea life, the history of the ocean, and the secrets of our planet. It is truly one of the greatest natural wonders in the world.
