Active and passive margins describe the various characteristics of continental margins that are a result of plate tectonics. An active margin usually has numerous volcanoes and mountains, while a passive margin typically do not have these formations.
An active continental margin may have a trench.
A subduction zone would be found at an active continental margin, where one tectonic plate is being forced beneath another. This process leads to features such as deep ocean trenches, volcanic arcs, and earthquakes. In contrast, passive continental margins lack these tectonic interactions and are characterized by a relatively smooth transition from continent to ocean basin.
Broad sediment-covered continental shelves are typically found in passive margins where there is a lack of tectonic activity and the crust is stable. Active margins, on the other hand, are associated with tectonic activity like subduction zones or rift zones, which can result in narrower shelves due to more abrupt changes in the seafloor elevation.
At a passive continental margin, you would find a continental shelf, which is the shallow, relatively flat platform extending from the shoreline, and a continental slope, which is a steeply sloping transition zone between the continental shelf and the deep ocean floor.
Both active and passive margins are found at the edges of continents. Active margins are associated with tectonic activity and are typically marked by earthquakes, volcanoes, and mountain building, while passive margins are geologically stable and characterized by broad continental shelves and sediment deposition.
An active continental margin may have a trench.
An active margin typically features tectonic activity such as earthquakes and volcanic eruptions, due to its proximity to tectonic plate boundaries. This contrasts with a passive margin, which is characterized by stability and minimal geological activity. Additionally, active margins often have steep coastal cliffs and narrow continental shelves, while passive margins tend to have wide continental shelves and gentle slopes.

Shale, sandstone, and limestone.
At a passive continental margin, you would find a continental shelf, which is the shallow, relatively flat platform extending from the shoreline, and a continental slope, which is a steeply sloping transition zone between the continental shelf and the deep ocean floor.
Continental margins can be labeled as either active or passive. Active margins are typically found along tectonic plate boundaries, featuring steep coastlines, narrow continental shelves, and significant geological activity such as earthquakes and volcanic activity. In contrast, passive margins are located along stable tectonic plates, characterized by broader continental shelves, gentle slopes, and less geological activity. Each margin type can further be divided into sub-zones, including the continental shelf, slope, and rise.
either active continental crust or passive continental crust.
Active transportation and passive transportation (found in facilitated diffusion and osmosis)
Both active and passive margins are found at the edges of continents. Active margins are associated with tectonic activity and are typically marked by earthquakes, volcanoes, and mountain building, while passive margins are geologically stable and characterized by broad continental shelves and sediment deposition.
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.
Active systems have a much longer range than passive systems due to having an internal battery. Because of this an active tag will be much larger and more expensive than a passive tag. The passive tag will basically convert the RF signal from the Interrogator or reader and turn it into energy to return the signal. Active tags will often be found on larger sized shipping containers/products whereas a passive tag, due to its small form factor can be used on any variety of products, containers, boxes...etc. Passive tags are usually more durable than active tags. While some active tag batteries have a lifetime of 10 years, depending on the frequency of use, passive tags do not have the handicap of internal power requirements. Depending on the harshness of the environment, an industrial grade passive Read-Only tag can last longer than your average person.
