GEOLOGY

Detailed explanation-1: -"Remote sensing is the art and science of obtaining information from a distance, i.e. obtaining information about objects or phenomena without being in physical contact with them.

Detailed explanation-2: -Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance (typically from satellite or aircraft). Special cameras collect remotely sensed images, which help researchers “sense” things about the Earth.

Detailed explanation-3: -Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object, in contrast to in situ or on-site observation.

Detailed explanation-4: -Detailed Solution. The correct answer is Images.

Detailed explanation-5: -The most typical example of such devices is radar (operating with microwaves). The basic two types of remote sensing in this category are: imaging (two-dimensional, e.g., radars); non-imaging (linear, e.g., altimeters or scatterometers).
