How were the Himalayas formed?

Different plates in the world
(Please read the blog from bottom to the top)The earth was composed of several giant plates called tectonic plates.The most accepted theory is thatIndia once belonged to an Island continent called Gondwanaland and was separated from the Eurasian continent by the primordial Tethyan ocean. One billion years ago, the Aravallis, whose eroded remnants are visible around Delhi, formed a chain higher than the Himalayas today. Over millions of years these mountains suffered the forces of erosion and their sediments were deposited in the Tethyan ocean. Then 140 million years ago, India began it's northward movement, on a collision course with the Eurasian continent.

People of the Himalayas

A Sherpa guide
The Sherpas-

The Sherpa is a member of a traditionally Buddhist people of Tibetan descent living on the southern side of the Himalaya Mountains in Nepal and Sikkim,they have a total population of about 150,000."Sherpas" is also used to refer to local people,  who are employed as guides for mountaineering expeditions in the Himalayas.

They are now world renown as expert guides on Himalayan mountaineering expeditions.They prove to be extremely valuable to early explorer of the Himalayan region, serving as guides and porters at the extreme altitudes of the peaks and passes in the region.

Climate and vegetation

Climate-The Himalayas is covered in snow and
the temperature reach up to -60 on an average a day.The Himalayan Alpine climate varies according to the elevation. It gets colder as the elevation increases and gets wetter as the elevation drops. As a result the temeparture and climatic changes in the Himalayan regions change very quickly. All of a sudden there can be occurances of monsoons, floods, high winds, snowstorms..... which makes the climate over here quiet an unpredictable and dangerous one.

The two major seasons of the Himalayan region are winter and summer. During the winter the region recieves the a lot of snow and very low temperatures. Summer are quiet mild over here, making the places overe here quiet good summer holiday hideouts. Usually throughout the year te Alpine Himalayan region recieves Snow.

Vegetation-
Because of the region's freezing temperatures, low levels of oxygen and strong winds(due to the highaltitude ), plants grow closer to the ground and have short growing seasons.Forests may also be found at the low altitude regions.

Orchid(they use this part to pollinate)
Plants like Rhododendrons,Orchids,Blue Poppies,Geraniums,Begonias........ can be found.

Mount Everest

Mount Everest rise above the clouds

Mount Everest,is the world's highest mountain above the sea level at 8,848 metres (29,029 ft). It is located in the Himalayas on the Nepal (Sagarmatha Zone)-China (Tibet) border.The Tibetan name for Mount Everest is Chomolungma or Qomolangma whichwhich means "Saint Mother."
Location on the Sagarmatha Zone, Nepal – Tibet, China border

Numerous attempts to climb Everest were made from 1921; the summit was finally reached by Edmund Hillary of New Zealand and Tenzing Norgay of Nepal in 1953. In dispute is whether the English explorer George Mallory, whose body was discovered below Everest's peak in 1999, had actually reached the peak earlier, in 1924, and was descending it when he died. The formerly accepted elevation of 29,028 ft (8,848 m), established in the early 1950s, was  recalculated   in the late 1990s.

The Himalayas!

Himalayas is located in the Eurasian contient
Introduction-The Himalaya Range or Himalaya Mountains usually called the Himalayas or Himalaya for short, is a mountain range in Asia, separating the Indian subcontinent from the Tibetan Plateau. the Himalayan mountain system is the planet's highest, and home to the world's highest peaks, the Eight-thousanders, which include Mount Everest and K2.(note-this is done solo and I have great diffculties making this since It was the first time,also please read from the bottom first.)
