continental drift... the interesting things happen at the edges when another plate isn't moving in the same direction at the same speed.
NB: the answer "they drop the box and smash it" is likely to get chuckle as long as you can follow up with the right answer.
When regional tensile tectonic stresses develop, there is initially the formation of tensile structural features which take the form of horst and graben structures. These are downthrown blocks of crust separated by normal faults. If the tensile deformation continues, rifting and rift related volcanism may begin to occur due to the thinning of the crust and the loss of confining pressure on the underlying mantle material causing decompression melting. Ultimately if the tensile stresses persist, the rift will form a new ocean and ultimately a new mid-ocean-ridge.
This process is currently occurring in the east African rift zone.

When continental plates collide the result is mountain building. Eventually the two plates will become merges together.
Mountain chains are created, I think.
The oceanic plate usually subsides after colliding with a continental plate.
an example of this is the marinas trench of the coast of japan and the continental plate of the Philippine's. the more denser oceanic plate is forced under by the lighter continental plate. this normally happens at destructive plate margins.
When an oceanic plate converges with a continental plate, the oceanic plate slips under the continental one and into the mantle in a process called subduction. The area will be prone to large earthquakes and tsunamis. A chain of volcanoes will form on the continent.

When the oceanic plate sinks it is absorbed back into the magma.
Earthquakes, tsunami's. you name it and it could happen

Subduction. denser oceanic plate moves under the continental plate. The oceanic plate is submerged into the mantle causing magma to rise to the surface.
the nazca plate will move under the south american plate.
