Answers
Answer:
The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today.
Answer:
Types Of Wind
Wind in simple terms is nothing but moving air. We all enjoy wind rustling through the leaves in our garden. It has also expanded the range of transport and has provided a power source in terms of mechanical energy for the generation of electricity in windmills and recreation purposes in hot air balloons. Wind power was also used in voyages by sailors to direct their ships. When the winds are strong, they lead to the destruction of life and property in the form of cyclones and storms, causing forest fires, landslides etc. In this article, we will learn about the causes of wind and the destruction caused by winds.
Types of Wind
Wind blowing above the earth surface may be classified into five major types:
Planetary winds
Trade winds
The westerlies
Periodic winds
Monsoon winds
Land breeze
Sea breeze
Mountain and valley breeze
Local winds
Types of wind
Planetary Winds
Planetary winds comprise winds distributed throughout the lower atmosphere. The winds regularly blow throughout the year confined within latitudinal belts, mainly in north-east and south-east directions or from high-pressure polar-regions to low-pressure regions.
Trade Winds
These winds are also known as tropical easterlies and blow from the right in Northern hemisphere and to the left in the Southern hemisphere due to Coriolis effect and Ferrel’s law. They start blowing from the sub-tropical high-pressure areas towards the equatorial low-pressure belt. In the Northern hemisphere, they blow as northeastern trades, and in the Southern hemisphere they blow as southeastern trades.

The Westerlies
These winds are also known as Shrieking Sixties, Furious Fifties, and Roaring Forties. They blow from the subtropical high-pressure belts towards sub-polar low-pressure belts. The westerlies of Southern hemisphere are stronger and constant than the westerlies of Nothern hemisphere.
Periodic Winds
These winds change their direction periodically as there is a change in the seasons. Following are the types of periodic winds:
Monsoon winds: The temperature difference created by the Indian Ocean, Arabian Sea, Bay of Bengal and Himalayan wall forms the basis of monsoon in the Indian subcontinent.
Land breeze: These winds blow from land to sea, carrying no moisture but dry and warm.
Sea breeze: These winds blow from sea to land, carrying some moisture.
Mountain and valley breeze: Valley breeze is the hot air blowing from the valley which flows up to the slopes of mountain slopes. In contrast, mountain breeze is the valley breeze that is the cold air from the mountain flow towards the valley.
