Atmosphere MCQ Question and Answer | Geography MCQ Question

Tropical cyclones, including hurricanes and typhoons, can develop and mature anywhere within the tropical zone. The tropical zone encompasses the region between the Tropic of Cancer and the Tropic of Capricorn, which includes warm ocean waters in tropical and subtropical regions around the globe. These cyclones form over warm ocean waters, where the sea surface temperatures are typically above 26.5°C (80°F), providing the necessary energy for their development. The warm and moist air near the ocean's surface rises and creates a spinning motion due to the Earth's rotation, leading to the formation of these cyclonic systems. As they move across the warm waters, tropical cyclones can intensify and become powerful storms. Therefore, they can develop and mature anywhere within the tropical zone.

The monsoon has well-developed cycle in South and South East Asia. The monsoon through axis experiences considerable day to day variation in its position, which has a vital bearing on the monsoon rainfall distribution in the region.

Westerlies in southern hemisphere are stronger and persistent than in northern hemisphere because southern hemisphere has less landmass as compared to northern hemisphere.

A layer in the Earth's atmosphere called Ionosphere facilitates radio communication.

Temperate lows are Sub-polar low pressure belts. The Coriolis effect from earth's rotation sets the resulting winds into Hadley cells, which produces low pressure at the equator and sub polar areas, high pressure at mid latitudes, and low sub-polar pressures, as well as trade winds, doldrums, and jet streams.

The plane of contact of the troposphere and stratosphere is known as tropopause. The tropopause is the boundary region between the troposphere and the stratosphere.

The ozone layer is mainly found in the lower portion of the stratosphere from approximately 20 to 30 kilometres (12 to 19 mi) above earth, though the thickness varies seasonally and geographically.

In the northern hemisphere, south-facing slopes are warmest because the sun stays mostly in the southern half of the sky.

Ozone is the layer in Stratosphere with in atmosphere. It shields Earth from harmful UV rays of Sun. But, due to pollution and continuous exposure to green house gases a hole has developed in Ozone above Antarctica near South pole.

The general characteristics associated with tropical cyclones are that they are confined to a particular period of the year (mainly summer) and normally move from east to west.
