remote sensing remote sensing eyes in the sky and data analysis mapping skills geography

  1. Aeronautics engineers

  2. Space scientists

  3. Map makers

  4. Photographers

Show answer
Correct Option: C
Explanation:

Aerial photographs were the first result of remote sensing utilized by the cartographers, or map makers. In 1858, French map-makers used a hot air balloon and primitive cameras to take inclined aerial photographs of the landscape.

  1. Letters

  2. Television

  3. Telephones

  4. Telegraph

Show answer
Correct Option: B
Explanation:

Mass media is a part of everyone's life today. They are referred to as ‘mass’ media because they reach mass audiences – audiences comprised of very large numbers of people. Out of the given options television is a means of mass communication. In India, television programming was introduced in 1989. Since then it has been used for various reasons e.g., to promote education, disseminate information, entertainment. Moreover, television leaves a great impact on the viewers. The growth in television in both technology and reach is remarkable.

  1. El-Nino effect

  2. CFC releases

  3. Cyclones in the Bay of Bengal

  4. Rains in the Himalayan region

Show answer
Correct Option: A
Explanation:

El-Nino derived from Spanish means 'the child',i.e. baby christ. A warm ocean current that flows over Peru is an interval of two to five years.

After energy has been emitted by the target, the sensor collects and records the _____.

remote sensing remote sensing eyes in the sky and data analysis mapping skills geography

  1. Sunrays

  2. Objects on Earth

  3. Electromagnetic radiation

  4. None of these

Show answer
Correct Option: C
Explanation:
  • Once the energy makes its way to the target through the atmosphere, it interacts with the target depending on the properties of both the target and the radiation.
  • After the energy has been scattered by, or emitted from the target, we require a sensor (remote - not in contact with the target) to collect and record the electromagnetic radiation.
