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.
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.
No. There is no such thing as a passive plate edge. They are near a passive continental margin.
At a passive continental margin, you would typically find extensive shelf sediments and a broad continental shelf, which accumulate over time due to the lack of tectonic activity. Additionally, features such as deltas and estuaries are common as rivers deposit sediment into the ocean. In contrast, active continental margins are characterized by steep slopes, narrow shelves, and geological features like subduction zones and volcanic arcs, which are not present at passive margins.
The narrow continental margin is typically found along passive continental margins, where the continental shelf is relatively small and steep. This type of margin is characterized by a gentle slope leading to the continental slope, followed by the continental rise and then the abyssal plain. Such margins often have limited sediment accumulation and are less tectonically active compared to wider margins. They play a crucial role in marine ecosystems and can influence ocean circulation patterns.
On a passive continental margin, you can find thick sedimentary layers, wide continental shelves, and less seismic activity compared to an active continental margin.

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.
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.
