This is known as a rift valley. it forms at a divergent boundary.

∙ 13y agoA deep valley where two tectonic plates move apart is called a rift valley. This occurs due to divergent plate tectonics, where the plates separate and magma rises to create new crust. Examples include the East African Rift Valley and the Mid-Atlantic Ridge.

∙ 13y agoThe boundary where two lithospheric plates are moving apart is called a divergent boundary, and the valley between them is called a rift valley. This is the source of sea-floor spreading.

The deep crack is called a rift valley. It forms where tectonic plates are diverging or moving apart, allowing magma from below the Earth's surface to rise and create new oceanic crust.
The prominent feature of the Mid-Atlantic Ridge is a very deep linear valley known as a rift valley. This rift valley forms due to the tectonic plates moving apart and allowing magma to rise from the mantle, creating new oceanic crust in the process.

The huge trough down the center of the mid-ocean ridge is where two tectonic plates are moving apart. As they separate, magma rises up from the mantle to fill the gap, creating new oceanic crust. This process is known as seafloor spreading.
When two of Earth's oceanic plates collide, they can form a deep valley called a trench. Trenches are often found in subduction zones where one plate is forced beneath the other, creating a deep depression in the ocean floor.
The answer to that very question that you have just stated i will answer. It is a simple RIFT VALLEY :)

When tectonic plates diverge on land, they often form rift valleys or rift zones. These are characterized by large fissures, volcanic activity, and minor earthquakes. Over time, the continuous separation of the plates can lead to the formation of new ocean basins.

A divergent plate boundary is where two tectonic plates are moving away from each other. This movement typically leads to the formation of new crust as magma rises and solidifies at the boundary, creating features like mid-ocean ridges or rift valleys on continents.
At collision, mountains, at separation, long deep holes into the earth.
The Celtic word for deep valley is "gleann domhain."
