A ridge is a long, elevated landform consisting of a series of hills or mountains that are connected. It is typically formed by tectonic activity, such as the collision of tectonic plates. A trench, on the other hand, is a long, narrow depression in the ocean floor. Trenches are usually formed where one tectonic plate is subducted beneath another, creating a deep and steeply inclined boundary.
A trench stretch is a long system of trench.
yes there was, there was usually a base trench, and close by was a suppport trench
At the front there was the front line, then there was the support trench and at the back was a reserve trench.
The world's largest trench is the marina trench which is found right above japan.

It is The Marianas trench it is the deepest underwater canyon and i believe the longest at 1580 miles.The mid atlantic ridge stretches 10,000 miles!
It's often called a trench.
A valley underwater is called a submarine canyon. These can form through a variety of geological processes, such as erosion by underwater currents or the collapse of underwater sediment. Submarine canyons can be important habitats for a diverse range of marine life.
The Volcanic Marianas Islands form west of the Marianas trench because plates are formed by underwater volcanoes which will move gently to the west.
Type your answer here... he was a underwater bathesphere explorer. made it to the bottom of the Marianis trench 36000 ft
The Philippine Trench (also known as the Manila Trench) is a deep underwater trench that is caused by the collision of two tectonic plates (the Philippine Sea Plate and the Eurasian Plate) east of the Luzon island of the Philippines. The Eurasian Plate is subducting underneath the Philippine Sea Plate at a rate of approx. 16 cm/year. This tectonic activity causes most of the volcanic activity on Luzon, including the cataclysmic eruption of Mt. Pinatubo in 1991.
