When you have transform plate boundaries, the continental crusts push on each other in the opposite direction. The crusts get stuck until a tremendous amount of energy is released. This energy is known as earthquakes. If oceanic crusts have transform plate boundaries, tsunamis are a possibility.
Converging plates move towards each other, and can be oceanic or continental plates. They usually make mountains on continental crusts, and trenches in the oceans with oceanic crust. If one plates goes under the other, underwater or other volcanoes start to appear. If oceanic and continental plates collide, deep sea trenches are formed.
Divergent plates move apart from each other, and make ridges in the oceans. On the continental crust, diverging plates make the Earth's crust slowly shift and move. Ocean rifts are created when magma is exposed to the ocean by diverging plates.
