Trenches are formed by divergent plates, Whereas Ridges are formed by plate in collision.
Deep Trench in the ocean floor. It can sometimes be mistaken for a mid-ocean ridge.
The term for the natural gap in a mountain ridge is called a "pass" or a "col." These are low points that allow for easier travel between two adjacent valleys or mountain peaks.
Yes, a large trench known as the Mid-Atlantic Ridge runs down the middle of the Atlantic Ocean basin. This underwater mountain range is where tectonic plates are moving apart, causing new oceanic crust to form in the process.
hard to say
usually a rift or trench
Yes, plate movement can occur through a process called ridge push. As new oceanic crust forms at mid-ocean ridges, it pushes the neighboring tectonic plate away from the ridge due to the force of gravity, causing the plate to move away from the ridge. This movement is one of the driving forces behind the motion of tectonic plates.
