- Question 1 of 5
1. Question
Consider the following statements.
1. All planets between the Earth and the Sun in our solar system contain volcanoes.
2. There is evidence for the existence of ice, as well as water, on the surface of planets other than earth.
Which of the above is/are correct?CorrectSolution: c)
Both the statements are correctIncorrectSolution: c)
Both the statements are correct - Question 2 of 5
2. Question
The Terrestrial and Jovian planets are largely differentiated on the basis of loss of atmosphere from the former. Which of the following characteristics of terrestrial planets enabled this loss of atmosphere?
1. Their larger size as compared to most Jovian planets
2. Their nearness to Sun
Which of the above is/are correct?CorrectSolution: b)
Justification: Statement 1: It can be easily discarded. Jovian planets (Jupiter, Saturn etc) are bigger in size than terrestrial planets (earth, Venus etc)IncorrectSolution: b)
Justification: Statement 1: It can be easily discarded. Jovian planets (Jupiter, Saturn etc) are bigger in size than terrestrial planets (earth, Venus etc) - Question 3 of 5
3. Question
Which of the following contribute to the appearance of the Blood Moon?
1. Relative positions of earth, sun and moon
2. Refraction of light travelling through the Earth’s atmosphere
Select the correct answer using the codes below.CorrectSolution: c)
Both the statements are correctIncorrectSolution: c)
Both the statements are correct - Question 4 of 5
4. Question
Cycle of ‘Solar spots’ can significantly affect the climate on earth by leading to a
1. Change in solar output
2. Reversal of earth’s magnetic field
Which of the above is/are correct?CorrectSolution: a)
Justification: Statement 1: Sunspots are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions. For instance, solar energetic particles and cosmic rays could reduce ozone levels in the stratosphere. This in turn alters the behavior of the atmosphere below it, perhaps even pushing storms on the surface off course They reduce solar output if increase in number. So, 1 is correct.
Statement 2: The Sun’s magnetic field structures its atmosphere and outer layers all the way through the corona and into the solar wind. Solar spots reflect intense magnetic activity on the Sun at those spots, and not earth.

5. Question
Nanoflares are related to
CorrectSolution: b)
Justification: A nanoflare is a very small episodic heating event which happens in the corona, the external atmosphere of the Sun. According to Parker a nanoflare arises from an event of magnetic reconnection which converts the energy stored in the solar magnetic field into the motion of the plasma. Telescopic observations suggest that the solar magnetic field, which theoretically is “frozen” into the gas of the plasma in the photosphere, expands into roughly semicircular structures in the corona.IncorrectSolution: b)
