Q.2) Consider the following statements:
1. Asteroids are formed of an atmosphere of dust and gas and, sometimes, a tail of dust and/or gas.

Ans. B
Explanation:
Asteroids are small, airless rocky worlds revolving around the sun that are too small to be called planets. They are also known as planetoids or minor planets.
In total, the mass of all the asteroids is less than that of Earth’s moon. But despite their size, asteroids can be dangerous. Many have hit Earth in the past, and more will crash into our planet in the future.

Q.4) Consider the following statements with respect to ‘Sun Spots’ and choose the correct ones:
1. Sunspots are dark and cooler patches on the sun.
2. They increase or decrease the temperature of the sun.
3. A decrease in sunspot numbers is associated with warm and drier conditions.
Select the correct answer using the code below:
a) 1 and 3 only
b) 1 and 2 only
c) 2 and 3 only
d) 1, 2 and 3
Ans. D
Explanation: The causes for climate change are many. They can be grouped into astronomical and terrestrial causes. The astronomical causes are the changes in solar output associated with sunspot activities. Sunspots are dark and cooler patches on the sun which increase and decrease in a cyclical manner. According to some meteorologists, when the number of sunspots increase, cooler and wetter weather and greater storminess occur. A decrease in sunspot numbers is associated with warm and drier conditions. Yet, these findings are not statistically significant.
