What does a ocean to continent boundary cause?

An ocean to continent boundary typically results in the formation of subduction zones, where an oceanic plate is forced beneath a continental plate. This process can lead to geological phenomena such as earthquakes, volcanic activity, and the creation of mountain ranges. Additionally, it contributes to the recycling of the Earth's crust and affects oceanic and atmospheric circulation patterns. Overall, these boundaries play a crucial role in shaping the Earth's geology and ecosystems.
