Explain the role of the atmosphere as a blanket. List the factors that decide the rainfall patterns.

(N/A) The atmosphere acts as a blanket because air is a bad conductor of heat. It prevents the sudden increase in temperature during the daylight hours and slows down the escape of heat into outer space during the night,thereby keeping the average temperature of the Earth fairly steady.
$(b)$ The factors that decide the rainfall patterns are:
$1$. The direction of prevailing winds.
$2$. The presence of mountain ranges or geographical barriers.
$3$. The proximity to large water bodies like oceans or seas.
$4$. The temperature variations in different regions.
