Answer: Option B. -> Equatorial region
Answer: (b)
Convection rain commonly occurs in warmed or heated areas such as equatorial/tropical regions, where there is an almost daily occurrence and even distribution of rain, and temperate areas in summer.
It is also common in the inter-tropical convergence zone (ITCZ). It happens when the ground surface is locally overheated and the adjacent air, heated by conduction, expands and rises.

Answer: Option B. -> Troposphere
Answer: (b)The troposphere is the lowest layer of the Earth’s atmosphere. The air is very well mixed and the temperature decreases with altitude.

Answer: (b)
Answer: (b)
Answer: Option A. -> Tundra
Answer: (a)
Answer: (a)
Answer: Option A. -> Ionosphere
Answer: (a)Ionosphere is composed partly of electrons and positive ions. It is a region of Earth’s upper atmosphere, from about 60 km to 1,000 km altitude, that is ionized by solar radiation. This layer is also called thermosphere as its temperature rises with height.

Answer: Option C. -> Chinook
Answer: (c)
“Chinook”, originally meant a warming wind from the ocean into the interior regions of the Pacific Northwest (the Chinook people lived near the ocean, along the lower Columbia River).
A strong Chinook can make snow one foot deep almost vanish in one day. The snow partly melts and partly evaporates in the dry wind. Chinook winds have been observed to raise winter temperature, often from below -20°C (-4°F) to as high as 10-20°C (50-68°F) for a few hours or days, then temperatures plummet to their base level.

Select the correct answer using the code given below:
Answer: Option A. -> 1 and 2
Answer: (a)
Tornado–A rapidly rotating column of the air developed around a very intense low-pressure area, associated with a dark funnel-shaped cloud, originate in the USA.
The air is anticlockwise in the northern hemisphere and clockwise in the southern hemisphere.
