On a passive continental margin, you can find thick sedimentary layers, wide continental shelves, and less seismic activity compared to an active continental margin.
Subduction. A subduction trench.
An active continental margin may have a trench.
Yes, the East African Rift Valley is an example of an active margin. Active margins are locations where tectonic plates are moving and causing geological activity such as earthquakes, volcanic eruptions, and the creation of new crust. The East African Rift is actively spreading apart, causing the region to slowly split into two tectonic plates.
A passive continental margin is not tectonically active, meaning it does not experience significant geological activity like earthquakes or volcanic eruptions. In contrast, an active continental margin is located near a tectonic plate boundary, leading to geological activity such as subduction zones, earthquakes, and volcanic eruptions.

No, the continental margin of Fort Myers is not considered an active continental margin. Active continental margins are typically associated with tectonic activity, such as subduction zones or plate boundaries, which are not present in the area surrounding Fort Myers.
On an active continental margin, you would be likely to find an active ocean trench. This structure would generally not occur at a passive continental margin.
You would need to find a continental rift. The best example of an active continental rift is the East African Rift.

No, active continental margins typically do not have a continental rise. Instead, they often have a steep continental slope that descends into a deep oceanic trench due to tectonic activity. Continental rises are found at passive continental margins where there is minimal tectonic activity.

The U.S. east coast is not considered an active continental margin because there are no plate boundaries near it. Off the coast there is merely a slope with a transition from continental to oceanic crust.
