1. Auroras are primarily visible near the equator and are devoid of in the polar regions.
2. Auroras occur due to the collision of charged particles from the Sun with Earth's
atmosphere.
Answer: B
Explanation
● An aurora is a natural phenomenon which is characterized by a display of a natural-
coloured (green, red, yellow or white) light in the sky.
● It is a light show which is caused when electrically-charged particles from the sun
collide with particles from gasses such as oxygen and nitrogen present in the Earth’s
atmosphere. Hence statement 2 is correct.
● Aurora is sometimes referred to as ‘polar light’. It is predominantly seen in the regions of
high altitudes like the Arctic and Antarctic. Hence statement 1 is incorrect.
