trench
The deep valley that lies along the east coast of Africa is called the East African Rift Valley. It is a tectonic plate boundary where the African Plate is splitting into two, causing the valley to form.
The challenger deep was formed when the Philippine plate and the pacific plate had a collision forced the heavier pacific plate down toward the mantle, and the edge of the Philippine plate was dragged down creating a steep walled trench.

The oceanic plate is forced beneath the continental plate in a process called subduction. This collision can lead to the formation of deep oceanic trenches, volcanic arcs, and earthquakes due to the intense pressure and friction between the two plates.
Subduction is a result of a collision between two tectonic plates, either oceanic to oceanic collision or oceanic to continental plate collision. The heavier, or more dense plate sinks under the more buoyant less dense plate, and is drawn down into the upper mantle.
Deep ocean trenches are evidence for plate tectonics, showing where one tectonic plate is subducting beneath another. These trenches form at convergent boundaries when the denser oceanic plate sinks into the mantle. The presence of deep ocean trenches also indicates areas of seismic activity and potentially tsunamis.
The collision of an oceanic plate with a continental plate typically results in subduction, where the denser oceanic plate sinks beneath the continental plate, creating features like deep ocean trenches and volcanic arcs. In contrast, the collision of two continental plates leads to the formation of mountain ranges due to the compression and buckling of the crust, as neither plate is subducted easily. This process can create significant geological activity, such as earthquakes, but generally lacks the volcanic activity associated with oceanic-continental collisions.
generally in mountain ranges
Convergent plate boundaries
celtic for valley is comb but i dont know about deep valley
deep valley i think :)
The feature that marks the location where one tectonic plate is pushed underneath another plate is called a subduction zone. In these zones, the denser oceanic plate is typically forced down into the mantle beneath a lighter continental plate or another oceanic plate. This process can lead to the formation of deep ocean trenches and is often associated with volcanic activity and earthquakes.
