Explain how an aurora is produced.
  What will be an ideal response?

Question 2

Explain why the Kelvin temperature scale is also called the absolute temperature scale.
  What will be an ideal response?

Answer to Question 1

ANSWER: An aurora is produced by solar wind disturbing the magnetosphere. The disturbance involves high-energy particles within the magnetosphere being ejected into Earth's upper atmosphere, where they excite atoms and molecules. The excited atmospheric gases emit visible radiation, which causes the sky to glow like a neon light.

Answer to Question 2

ANSWER: The Kelvin scale is named after Lord Kelvin (18241907), a famous British scientist who first introduced it. Absolute zero is the starting point for this temperature scale, which is why it is called the absolute scale. Because the Kelvin scale begins at absolute zero, it contains no negative numbers and is therefore quite convenient for scientific calculations. Absolute zero or 0 Kelvin (-273 degrees Celsius; -459 degrees Fahrenheit) is the lowest temperature possible; at this temperature atoms and molecules would possess a minimum amount of energy and theoretically no thermal motion.
