Answer:
Passive margin
Explanation:
The edge of a continent can be of two types:
- Active margin: a continent edge is said to be an active margin if it lies near a plate boundary. In this case, the two plates can move past each other, giving birth to geological activity (e.g. earthquakes). An example of active margin is the US west coast, which lies at the boundary between the Pacific plate and the North American plate
- Passive margin: a continend edge is said to be a passive margin if it does not lie near a plate boundary. In this case, there is no geological activity. An example of passive margin is the US east coast.
