The process shown occurring at a deep ocean trench is subduction, where one tectonic plate is being forced beneath another into the Earth's mantle. This process is a key element of plate tectonics and is responsible for creating deep ocean trenches and volcanic activity.
The arrows shown in the asthenosphere represent the inferred slow circulation of the plastic mantle by a process called mantle convection. This process involves the movement of heat from the Earth's core towards the surface, creating a pattern of circulation that drives plate tectonics and other geologic phenomena.
Other than abundant matching fossils and sedimentary rock on opposite sides of the Atlantic Ocean and the apparent puzzle piece appearance of the continents on either side of the Atlantic, there is the presence of the mid-oceanic ridges, areas where new oceanic crust is created. The magnetic orientation of the basaltic oceanic crust as it forms is the mirror image of the magnetic orientation of the basaltic oceanic crust on the other side of the ridge, indicating that the seafloor is spreading in both directions away from ridge. Additionally, the dating of rock on the ocean floor has shown that oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached. And finally, accurate measurements have been made by global positioning devices which verify that seafloor spreading is occurring.
The rock shown is likely composed of large crystals that were formed by slow cooling inside the Earth's crust, allowing mineral grains to grow to a visible size. This process typically occurs in intrusive igneous rocks like granite or pegmatite.
There are 12 buildings shown on the map.
Geological evidence has shown that the movement of tectonic plates, which make up the Earth's crust, is responsible for the continents moving apart. This movement is driven by the process of seafloor spreading, where new oceanic crust is formed along mid-ocean ridges, pushing the continents farther apart over time. This evidence is supported by studies of magnetic anomalies in seafloor rocks and the distribution of fossils and rock formations across different continents.
In a process taking tens of millions of years, part of the ocean floor sinks back into the mantle at deep ocean trenches.

Because it has been shown beyond doubt that the first form of life was ocean-borne.

The Arctic, North Atlantic and North Pacific oceans are all in the northern hemisphere.
