Arrange the elements of electromagnetic remote sensing of earth resources in sequential order.

A. Propagation of energy through the atmosphere
B. Energy Source
C. Re-transmission of energy through the atmosphere
D. Energy interactions with earth surface features
E. Detection, recording and transmission of data to ground stations by sensors

Choose the correct answer from the options given below:

Correct option is B

The correct order of elements in electromagnetic remote sensing begins with Energy Source (B), which provides the initial electromagnetic energy. Next, the energy propagates through the atmosphere (A). Then, the energy interacts with earth surface features (D). After this, the energy is re-transmitted through the atmosphere (C). Finally, the data is detected, recorded, and transmitted to ground stations by sensors (E).

1. Energy Source (B): The process starts with an energy source (such as the sun) that emits electromagnetic energy.
2. Propagation of energy through the atmosphere (A): The energy then travels through the atmosphere.
3. Energy interactions with earth surface features (D): Upon reaching the earth's surface, the energy interacts with features like land, water, and vegetation, and is reflected or absorbed.
4. Re-transmission of energy through the atmosphere (C): After interacting with the earth's surface, the energy may be re-transmitted back through the atmosphere.
5. Detection, recording, and transmission of data to ground stations by sensors (E): Finally, sensors on satellites or aircraft detect the re-transmitted energy, record it, and transmit the data to ground stations for analysis.

Information Booster:

1. Energy Source: The sun is the primary energy source in remote sensing, emitting electromagnetic radiation that is crucial for the process.
2. Propagation of Energy through the Atmosphere: Atmospheric conditions affect how energy travels, with factors like cloud cover and pollutants influencing the signal.
3. Energy Interactions with Earth Surface Features: The surface features (e.g., forests, water bodies, urban areas) influence the amount of energy reflected or absorbed, impacting data collected.
4. Re-transmission of Energy: The interaction of energy with the earth’s surface may lead to scattering, absorption, and reflection, causing energy to be transmitted back to the sensors.
5. Detection, Recording, and Transmission of Data: Sensors capture the reflected or emitted energy, which is converted into usable data and sent to ground stations for interpretation and analysis.
