Deep trenches in the ocean mark places where two tectonic plates are converging, with one plate being forced beneath the other. This process, known as subduction, is responsible for creating some of the deepest parts of the ocean.
Ocean trenches and volcanoes both occur where continental plates collide, or meet. An Ocean trench is also noted for the presence of a volcanic arc. This is right no joke:)
The mid-ocean ridges were discovered in the Atlantic Ocean after World War II. These undersea mountain ranges mark places where tectonic plates are moving apart, allowing magma to rise from below the Earth's crust. This discovery fundamentally changed our understanding of the structure of the ocean floor and led to the development of the theory of plate tectonics.
between gas mark 3 and 4.
Geologists identify plate boundaries by plotting the locations of earthquakes, volcanic activity, mountain-building, and oceanic trench formation. The three types of plate boundaries are divergent, convergent and transform.
Mid-ocean ridges mark these sites where the ocean floor is spreading apart. As the ridges continue to widen, a gap called a forms. Here molten material rises to build new crust. When molten material rises from the asthenosphere, cold ocean water cools the rock until it becomes solid. As the plates move apart, new cracks open in the solid rock. More molten material rises and hardens. The growing ridge stands high above the sea floor. The world's longest ridge, the Mid-Atlantic Ridge, runs the length of the Atlantic Ocean. Here the North and South American plates are moving away from the Eurasian and African plates. The ridge extends nearly 11,000 kilometers (6214 mi) from Iceland to near Antarctica. The rift valley is 24 kilometers (15 mi) wide and 9 kilometers (6 mi) deep-about 7 kilometers (4 mi) deeper than the Grand Canyon!
At most convergent boundaries, oceanic plates collide with either another oceanic plate or a continental plate, leading to the formation of ocean trenches. These trenches are deep, narrow depressions in the ocean floor that mark the site of subduction, where one plate is forced beneath another. Additionally, volcanic arcs may form parallel to the trench on the overriding plate due to the melting of subducted material.

Watergate's Deep Throat was W. Mark Felt of the FBI.
The zero mark, at the Prime Meridian, and the 180 mark, the "anti-meridian" in the middle of the Pacific Ocean, are the places where the same line is the edge of both east and west longitudes. But all of the lines ('meridians') that mark a constant longitude meet at the north and south poles.
No. Mid-ocean ridges mark divergent boundaries.

A trench is a hole that is much longer than it is wide, a narrow excavation. The usual applications of the term are: - the trenches used as manned fortifications, as in World War II - deep underwater chasms that typically mark the subduction of oceanic plates
yes and no cus deep blue took over his body so not realy

Some places I have traveled to and would mark on a map include Paris, Tokyo, New York City, and Sydney.

Yes, he does know.
