Subduction creates immense pressure and heat, melting the rock just below the surface of a fault line. The building pressure often gives way and causes volcanic events.
Volcanism isn't a word. Do you mean, why are volcanoes common in subduction zones?
You could find mountains, valleys, faults, subduction zones, trenches, or experience volcanism or earthquakes.
When one plate slides beneath another it carries volatiles such as water with it. These substances get into the mantle rock and lower the temperature needed for it to melt. This molten material then rises as it is less dense and forms volcanoes as it reaches the surface.

Houston is very unlikely to experience a tsunami. Most tsunamis originate at subduction zones of which there are none in the Gulf of Mexico. There are islands that would block a tsunami in between the Gulf and the nearest subduction zone. Most tsunamis that somehow find their way to Texas will be fairly small, though still capable of causing damage. Even in an event like this, Houston would be protected from the tsunami by Galveston Island and the Bolivar Peninsula.
Russia has 9 different time zones, 8 contiguous and another one in Kaliningrad.
Near subduction zones.
at the very bottom of the ocean, usally

usually you find most of the zones of earthquakes and volcanoes at a plate boundary.
They usually show up in desert zones.
there are 24 time zones
There are many explanation to your question. The most abundant type of rocks in collision zones are metamorphic rocks. But if there is a igneous it can as a result of convergence boundaries. In subduction zones where rising magma are penetrate through weaker rocks to form form lava and when solidified forms igneous rocks. You can also find them in accretion zones. Where 2 continental plates are accreted due to plate movement. They are not newly formed igneous. they have been there for years before accretion.
You could find subduction zones in the depths of the oceans, at some plate boundaries. At this location, you would observe one tectonic plate (a plate of lower density then the other) being slipped under another plate into magma. These are also known as destructive boundaries, because crust is being destroyed, (as opposed to diverent boundaries where leaking magma creates new crust.)
When one plate slides beneath another it carries volatiles such as water with it. These substances get into the mantle rock and lower the temperature needed for it to melt. This molten material then rises as it is less dense and forms volcanoes as it reaches the surface.
The best page to find out about international time zones is a page called "TimeAndDate". On their website you will find all the different time zones. You can even search after a particular city to find out what time it is in their timezone.
You can find Nintendo Zones in locations such as McDonalds, Bestbuy and Future Shop.
