Many Catholic churches traditionally move St Patrick's Day to another date if March 17 falls during Holy Week. Many immigrants from Ireland fled to other parts of the world, including Australia, Canada, the United Kingdom and the United States, in the 19th and 20th centuries.
Making the world better, one answer at a time. Passive continental margins are not areas of convergence. There is little volcanic and earthquake activity on passive margins. Active margins are areas of convergence where one plate is descending beneath another. They are associated with volcanic and earthquake activity.
A destructive plate boundary is sometimes called a convergent or tensional plate margin. This occurs when oceanic and continental plates move together. The oceanic plate is forced under the lighter continental plate [continental plate: A section of the crust that makes up the Earth's landmasses.] .onstructive plate boundary. A constructive plate boundary, sometimes called a divergent plate margin, occurs when plates move apart. Volcanoes are formed as magma wells up to fill the gap, and eventually new crust is formed.
