What are the conditions for a hurricane to form? Enumerate various categories of Hurricanes as per Saffir-Simpson hurricane scale.

A hurricane is a type of tropical cyclone storms, generally, begin as clusters of thunderstorms over tropical ocean waters. Conditions for the formation of Hurricane: High water temperature at least 26-27 Celsius Relatively moist air Very warm surface temperatures A ..

Explain the causes of the Indian Monsoon.

Monsoon means seasonal reversal of winds which brings rainfall due to moisturised winds passing over water bodies. Indian Monsoon is the seasonal phenomenon caused by the differences of temperature and pressure over water bodies and landmass. In summer, the movement ..

What is El Nino? Has the extreme El Niño become more often?

El Niño is a climate phenomenon that takes place over the equatorial Pacific. When there is a warming of the sea surface temperature in the eastern and central equatorial Pacific Ocean, it is known as El Niño. When the opposite ..

If the Earth's axis were tilted at 40° to the plane of the ecliptic instead of 23½°, what would be the effects of this change on (1) global climate and seasons (2) seasons and climate of India?

Seasons and length of day and night on earth are determined by tilt of earth’s axis wrt ecliptic plane, rotation around the axis and revolution on an elliptical path around sun. If Earth’s axis is tilted at 40o the impact ..

Explain the process of formation of a rift valley, emphasizing on the Great Rift Valley system.

Rift Valley is a depressed area between two adjacent highland areas. It is formed due to tectonic plates’ movement. They are found both on earth and under water. E.g. East African rift Valley, Narmada rift Valley. Process of Rift Valley ..

The third pole of the earth not only important for geographical reasons but also for economic and civilizational aspects of the Indian Subcontinent. Explaining the importance of the region, examine the consequences of its changing features.

The Inner Himalayan region, along with Trans Himalayas and Hindukush mountains is often described as the third pole of the world owing to its crucial role in climate regulation and vast source of fresh water in form of glaciers. It ..

Both the moist subtropical and moist continental climates are found on eastern sides of continents in the midlatitudes. What are the major factors that determine their temperature and precipitation cycles? How do these two climates differ?

Moist Subtropical Climate It is found on the eastern coast of continents just outside tropics. The climate is characterized by hot and humid summer and mild winter. Maritime influence modifies the climate and Cold aid air from inner continent brings ..

“Though much of the consumption of cocoa occurs in the mid-latitudes, the production is confined largely to West Africa, eastern part of Brazil and the Caribbean mainland and islands.” Discuss focussing on location factors.

Cocoa is a truly tropical plant and most of the producing areas lie below 1000 metres elevation. Cocoa tree grows best in areas of hot and humid climate. It needs a temperature of about 27°C in shade and the temperature ..
