Describe how plate tectonics causes major geological events such as ocean basins, earthquakes, volcanic eruptions, and mountain building.

Tectonic plates are plates that can move and react in different ways with each other, these movements vary and as they vary they give rise to different geographical features.

The plates were found to slide or rub against each other, and this is what makes this sea livable.

The earth's surface is a puzzle of plates the size of continents that rub and collide with each other, generating powerful processes that form mountains and transform landscapes. The planet's geological metabolism, especially that of its tectonic plates, is also responsible for making it habitable.

The movements that occur between the plates are as follows:

convergent (two plates collide against each other), divergent (two plates separate) and transformants (two plates slide side by side). These movements are not because they are, but are the consequence of the currents of different temperatures that occur in the mantle, therefore everything that is warmer rises and what is cold descends or falls.

The updrafts / rising / hot and descending / falling / cold of the mantle can explain the movement of the plates, acting as a kind of "stimulating roller" that moves them.

Explanation:

When they move, they cause earthquakes or tsunamis in large bodies of water, when they converge and collide with each other, it may be that they form both mountains and volcanoes, in the event that they have a conduit that connects said geographic feature with the hot magma or mantle.

And if divergent movements happen they could also be caused by earthquakes, tsunamis, and even geographic divisions or neocontinent formations.

It is important to clarify also that volcanoes or mountain structures do not form only in earthly or sea life where there is land, there is scientific evidence of this also happens under the sea or under deep fresh water.

nobody can learn anything from that map without seeing it. indeed, we must take your word for it that you even have a map.
