Worked practice questions

Which of the following is given as an example of a natural radiation rather than an artificial radiation?

  1. X-rays
  2. Ultraviolet radiation
  3. Radiation from atomic energy plants
  4. Radiation from a nuclear reactor mishap
Show answer and solution

Correct answer: B. Ultraviolet radiation

1. Radioactive pollution arises from natural and artificial sources. 2. UV and IR radiations are listed as natural radiations. 3. X-rays and radiations from atomic energy plants are listed as artificial. 4. Reactor-mishap radiation is artificial too, so the only natural one here is ultraviolet radiation. _Source: Balbharati (Maharashtra Board) Class 10 Science & Technology Part 2, Ch 4 "Environmental Management", p.49_

The United Nations Environment Program (UNEP) was established at a conference on human and environment in the year:

  1. 1986
  2. 1980
  3. 1972
  4. 1998
Show answer and solution

Correct answer: C. 1972

1. A conference on human and environment discussed environmental problems and set up UNEP. 2. This took place in 1972. 3. The years 1980 and 1986 belong to the Forest and Environment Protection Acts, not UNEP. 4. So the correct year is 1972. _Source: Balbharati (Maharashtra Board) Class 10 Science & Technology Part 2, Ch 4 "Environmental Management", p.49_

The National Green Tribunal was established for effective implementation of environment-related laws in the year:

  1. 2011
  2. 1986
  3. 2000
  4. 2010
Show answer and solution

Correct answer: D. 2010

1. The National Green Tribunal was created to enforce environmental laws effectively. 2. It was established in 2010. 3. The year 1986 is the Environmental Protection Act, 2000 is the Sound Pollution Rule, and 2011 is the E-waste rule. 4. So the correct year is 2010. _Source: Balbharati (Maharashtra Board) Class 10 Science & Technology Part 2, Ch 4 "Environmental Management", p.50_
