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:

The correct answer to the question is: B, A, D, C, E
Key Points

B. Energy Source:

• The remote sensing process begins with an energy source, which could be natural (e.g., sunlight) or artificial (e.g., radar).
• The energy source emits electromagnetic radiation.

A. Propagation of energy through the atmosphere:

• Once the energy is emitted by the source, it propagates through the atmosphere.
• The atmosphere may interact with and modify the energy, scattering or absorbing certain wavelengths.

D. Energy interactions with Earth surface features:

• The energy reaches the Earth's surface and interacts with the features present.
• These interactions vary based on the properties of the surface materials. Some energy may be reflected back, some absorbed, and some transmitted.

C. Re-transmission of energy through the atmosphere:

• After interacting with the Earth's surface, the energy is re-transmitted or reflected back towards the atmosphere.
• The re-transmission depends on the surface characteristics and the wavelength of the energy.

E. Detection, recording, and transmission of data to ground stations by sensors:

• Sensors on satellites or aircraft detect and record the re-transmitted energy.
• They measure the intensity of radiation across different wavelengths or bands.
• The recorded data is then transmitted to ground stations for further processing and analysis.

Therefore, the correct sequential order of the elements of electromagnetic remote sensing of Earth resources is:

2. B, A, D, C, E
