Dense oceanic crust slides under less dense continental crust
At a convergence boundary during collision of two plates there could either be Subduction or Outcropping. Subduction occurs when the collision involves plates of different types and densities while the other happens when it involves similar plate types. Mountain ranges are formed, also Subduction Zones gives rise to Trenches.
Subduction
the correct term is subduction zone. In geology, subduction is the process that takes place at convergent boundaries by which one tectonic plate moves under another tectonic plate, sinking into the Earth's mantle, as the plates converge. from wikipedia.com
For the most part, subduction of the Earth's plates don't have much effect on people - it happens, but there is nothing that changes what people do. However, it is possible for a sudden shift in the subduction zone to cause an earthquake, which necessarily is a rather large effect on the people in the area of the epicenter.
