Based on the three main north-south circulation cells, the rainiest latitudes on earth are expected to be
30o and the poles
30o and 60o
the equator and 60o
the equator and 30o

Option (4)

Explanation: According to the three circulation cells such as the Ferrel cells, Hadley cells and the Polar cells, the earth experiences maximum rainfall in the equatorial region, extending from the equator to about 30° latitude on both the hemisphere, covering the tropic of cancer as well as the tropic of capricorn.

This equatorial region is also known as the Inter Tropical convergence Zone (ITCZ), which is a low pressure belt. Due to the highest absorption of heat on this equatorial region, the area gets heated up, and causes the significant phenomenon for rainfall.

The rainfall is maximum here as the hot air rises up to the atmosphere and there converges the trade winds.

Thus, the correct answer is option (4).

The Tropics is an area on the surface of the Earth, which is geographically located around the equator, that is, bounded by two latitudes of 23.5 degrees latitude and 23.5 degrees latitude

Tropical plants and animals are species that live in the tropics. The term tropical is also sometimes used to refer to a place that is warm and humid throughout the year, even though it is not located between two back lines.

"Tropical" is sometimes used in a general sense for a tropical climate which means warm to hot and humid all year round, often with a feeling of lush vegetation.

Many tropical regions have a dry and rainy season. Areas with the rainy season are distributed throughout the tropics and subtropics. Under the Köppen climate classification, for tropical climates, the rainy month is defined as the month in which the average rainfall is 60 millimeters (2.4 in) or more. Tropical rain forests do not technically have a dry or rainy season, because the rainfall is evenly distributed throughout the year.

When the rainy season occurs during the warm season or summer, the rainfall falls, especially in the afternoons and evenings. The rainy season is a time when air quality improves, freshwater quality increases and vegetation grows significantly, leading to yields at the end of the season.

However, regions in the tropics may not have a tropical climate. Under the Köppen climate classification, most areas within the geographical area are classified not as "tropical" but as "dry" (dry or semi-arid), including the Sahara Desert, the Atacama Desert, and the Australian Outback.
