Nettet19. des. 2024 · A mid ocean ridge is a volcanic island chain located in the mid-ocean. Mid ocean ridges are where tectonic plates move, and volcanic activity occurs. They are located in the middle of the oceans and have long names. They are usually referred to as the “ridge”. They are the reason for the mid-ocean trenches and the Mid-Atlantic Ridge.

Nettet14. apr. 2024 · The volcanic activity in the ocean ridges is intense; Such is the level of lava expulsion to the surface that these formations can measure between 2000 and 3000 m in height. It is a considerable height if we take into account that it is only lava piled up at great depth and that the highest peak above sea level, Everest, is just over 8800 m. Nettet7. nov. 2024 · Ocean trenches are steep depressions in the deepest parts of the ocean [where old ocean crust from one tectonic plate is pushed beneath another plate, raising mountains, causing earthquakes, and forming volcanoes on the seafloor and on land. With depths exceeding 6,000 meters (nearly 20,000 feet), trenches make up the world’s … NettetMountains are some of the most impressive natural structures on earth. Yet how are these massive ridges in the Earth’s crust formed?The process that creates mountains is the large-scale movement of the Earth’s tectonic plates or the earth’s crust.. This movement can be broken up into different processes such as volcanic activity, folding, and faulting. princess and the rockstar
