Study about himalayas.

 

                            Himalaya 

Here's detailed explanation of the  himalayas , covering  its formation , location , dimension , geology , and biodiversity .

Formation of the himalayas.

Tectonic collision .

 The himalayas were formed  about 50  to 70 million  years ago  due to the collision  of the  indian plate  with the eurasians  plate . This process  is part of a larger phenomena known as plate tectonic.

Ongoing process.

The indian plates  continues to move northward  at about 5 Centimetre  per year , causing  the  himalayas to rises approximately 5 mm  annually, though this movement  also  leads to earthquakes in the region.

Mountain building.

As the indian plate subducted beneath the eurasian  plate,  sedimentary rocks from the tethys ocean were compressed, folded , and uplifted, forming the himalayas.

Young fold mountain.

The himalayas  are categorized  as "young  fold mountain"  because of their  relatively recent formation and steep, rugged  peaks.

2. Locaton and dimension.

Countries covered.

 The himalayas span  across four countries - India, nepal, bhutan,   and china ( tibet). 

Length.

Approximately 2400 km( 1500 miles)  from west ( nanga parbat , india  )  to east  ( namcha barwa, tibet ).

Width.

Varies  between 200 to 400 km. 

Area.

 Covers around  595000 square kilometre.

3 highest peaks.

The himalayas  are home  to 14  of the world's  highest  peaks  ( above 8000m). Some of the most  notable  peaks includes .

Mount everest ( 8848.86m/ 29031.7ft) located on the  nepal - tibet  border ,  it is the tallest  mountain in the  world.

K2 ( mount  godwin Austen) ( 8611m/28251ft)  located in india, it is  the  second  highest peaks.

Kanchenjunga ( 8586m/ 28169ft) -  located on the  india- nepal border, it  is the  third highest  peak.

Lhotse(8516m/27940ft) - near  mount Everest.

Makalu (8485m/27838ft) - on the  nepal - tibet  border.

4. geological composition  and types of rock. 

The himalayas consist of three distinct geological  regions.

Greater himalayas himadri.

 Composed of ancient , crystalline  rocks like gneiss and granite.

Includes the highest peaks  like  everest  and  kanchenjunga.

Covered  in glacier and  permanent   snow.

Lesser himalayas ( himachal).

 Composed of sedimentary   rock  such as  limestone  and shale.

Contains lush  valleys  and popular  hill stations.

Outer himalayas ( shivalik hills).

 Made up of alluvial  deposits , sand , and clay .

  Contains low  altitudes  hills and dense forests .

Biodiversity  of the himalayas.

 The himalayas have  an incredible  diverse ecosystem, influenced  by altitudes , climate, and geographical  location. 

Flora( plant life).

Tropical zone( up to  1500m)  - found in the  foothills , this zone includes sal,  teak, bamboo, and palm trees.

Temperate  zone ( 1500 to 3000m)  - Includes  oak, rhododendron, deodar, and pine forests.

Sub alpine  nd  Alpine  zone ( 3000 to  5000m)  -  Categorized by  juniper, birch , mosses, and lichens.

Limited  vegetation  above the  treeline .

Tundra zone ( Above 5000 M) - sparse  vegetation  with hardy plants like  lichens , and mosses.

Fauna ( animal life).

Mammals -  snow  leopard A  highly endangered  predator  found in alpine zones.

  

Red panda -  native to the eastern himalayas 

 Himalayas black bear - found in temperate  forests .

 Musk deer and tibetan wolf .

Birds- himalayan  monal ( national bird of nepal).

Lammergeier ( bearded  vulture) , pheasants and  eagles.

Reptiles  and amphibians  -  rare reptile  like  himalayan  pit  viper .

Aquatic life -  rivers  originating  from the himalayas  host fish  like Mahseer
