FOSSA DELLE MARIANNE, come si è formata e perché è cosi profonda

The Mariana Trench is the world's deepest ocean depression, located in the depths of the Pacific Ocean. There are many questions: What's at the bottom of the Mariana Trench? Have they really found a megalodon? Why is it so deep, and what would a trip to the Mariana Trench be like? The first surveys of the depths of this area of ​​the Pacific were made between 1872 and 1876 by the Challenger Expedition, the first oceanographic expedition, after which the deepest point of the trench is named. In this video, we explain how the Mariana Trench formed, how it was discovered, how deep it is, and what fish live there. Specifically, it is located in the northwest Pacific Ocean, east of the Mariana Islands, and is also known as the "deepest point on Earth." Its deepest point, the "Challender Deep," is located at 10,994 meters deep, almost 11 kilometers below sea level, with a temperature of 3 degrees Celsius. The submarine trench is shaped like an arc, approximately 2,500 kilometers long, and lies between the Pacific Plate and the Philippine Plate. The seabed is characterized by the presence of several underwater volcanoes. A true underwater kingdom shrouded in mystery due to its geological formation and the marine fauna that inhabit it. 00:00 Where is the Mariana Trench located? 00:10 How deep is it? 01:07 The discovery of the Mariana Trench 01:32 The dive of the Bathyscaphe Trieste 02:29 The deepest point on Earth 02:39 Why is it so deep? 03:50 What's in the Mariana Trench? 4:35 AM Temperature and Underwater Volcanoes SUGGESTED VIDEOS ▶ THE RELATIONSHIP BETWEEN TECTONIC PLATES AND EARTHQUAKES:    • Video   ▶ ITALIAN VOLCANOES AND EARTHQUAKES - WHY SO MANY?    • Video   ▶ OFFICIAL GEOPOP WEBSITE ◀ https://www.geologiapop.com/ ▶ TO SUPPORT THE GEOPOP PROJECT ◀ https://www.paypal.com/pools/c/8kNB7W... ▶ FOLLOW ME ON INSTAGRAM ◀   / geologiapop     / geologiapop
