Question

Statement 1 (S1): Aurora is a curtain of coloured lights that appears in the sky.
Statement 2 (S2): Aurora is caused by magnetic storms in the upper atmosphere.

• A. S1 is true but S2 is false.
• B. Both S1 and S2 are false.
• C. S1 and S2 are true and S2 is not the correct justification of S1.
• D. S1 and S2 are true and S2 is the correct justification of S1.

Answer 1

The correct option is A S1 is true but S2 is false.

A natural curtain of bright pink, red and green colour light that appears in the sky near the north and south magnetic poles is called Aurora. The interaction of charged particles from the Sun with atoms in the upper atmosphere causes this phenomenon. Though, geomagnetic storms triggered by the Sun also cause them.
