Question

Q. At perihelion, the earth is the nearest to the sun receiving more solar insolation than at aphelion. However, this variation in the solar output does not have a large effect on daily weather changes on earth at a certain point. This can be attributed to?

Select the correct answer using the codes below.

• A. 2 and 4 only
• B. 3 only
• C. 1 and 3 only
• D. 1, 3 and 4 only

Answer 1

The correct option is B 3 only

Explanation:

Statement 1 is incorrect: The solar wind is a stream of charged particles released from the upper atmosphere of the Sun. Planets with a weak or non-existent magnetosphere are subject to atmospheric stripping by the solar wind. It is not related to the distribution of weather.

Statement 2 is incorrect: Meteor showers do not affect day to day weather on earth.

Statement 3 is correct: Distribution of land and sea, heat transfer by way of sea and land breezes etc redistribute the increased insolation so that the effects are not felt largely.

Statement 4 is incorrect: Milankovitch effect refers to change in axis, shape and tilt of earth's spin. It is relevant to long term climate change, and not in this context which is about short-term weather changes.
