Active remote sensing transmits energy to allow an image to be formed. Passive remote sensing collects energy reflected or emitted from a surface. Active systems direct a bean of energy at a surface and analyze the energy reflected back. An example of active sensing would be a radar. Passive systems are pretty much what the eyes see, and it's like a photograph. Passive sensing radiates visible light.
Passive remote sensing picks up wave lengths of the light spectrum occurring on their own such light in photography. Active remote sensing will send out a wavelength of the spectrum and measure how it bounces back like radar.
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.

Active remote sensing uses its own electromagnetic radiation and use microwaves. It maps areas hard to map.

I broke my leg. (active voice) My leg is broken. (passive voice) Active voice vs. Passive voice.
Using the active voice makes sentences clearer, more direct, and easier to understand. It also usually creates a more engaging and dynamic writing style.
