Active remote sensing uses its own electromagnetic radiation and use microwaves. It maps areas hard to map.
Passive.
It can be either. A carrier pigeon is active whereas a malaria mosquito is passive.
it is active
Osmosis is an example of Passive Transport.
Active Transport is the passage of materials across the membrane through the expenditure of energy. Passive Transport is the passage of materials across the membrane without the expenditure of energy. Bulk Transport is the type of active transport. Diffusion and Osmosis are type of passive transport.
Remote sensing transmits energy that allows an image to be formed. Passive remote sensing collects energy that is reflected or emitted from a surface.
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.
