Oh,mighty mountains

December 11 is the International Mountain Day.It is a day to create awareness about the importance of mountains to life .The theme for this year's is food security in mountains.

Globe is meant to represent the Earth, right guys.But does it? Hardly

It doesn't represent Earth's shape at all-Earth is an 'oblate spheroid'.But Globe represents a round ball where land and water is there with its primary colors. The globe is also super smooth but is the earth ! NO.In earth there is plains, plateaus,valleys and, of course, Mountains.

In Indian  culture,Mountains have been honoured.they have a lot of histories in them and Histories yet to be discovered.Well, geologically speaking,they are not so old.

INTERESTING FACTS 

Earth is made up of three layers.The outer most crust ,under which are the mantle,outer core,and the inner core.The mantle is 'Molten Rock'which is thick and gooey and always moving in all directions.

The crust is made up of plates which are slipping and sliding on this gooey stuff .

This is where Mountains come  from.

Mountains affect the climate of the regions they are situated in.For example,if the Himalayas are not there,many parts of India would go so colder due to the northeast monsoon winds.

FIVE TYPES

• Magma (Molten rock from mantle)pushes up through the crust,and causes the crust to erupt,(e.g:Mt. Pinatubo, philippines)leading to the formation of  Volcanic mountains.
• In some places,magma's pressure pushes up the Earth's crust but doesn't erupt,leading to the formation of Dome mountains.(e.g Half Dome in California's Sierra Nevada).
• Sometimes the plates of the crust ("tectonics plates") collide and the crust deteriorate to form  fold mountains.
• When large areas of plateaus are eroded by rivers, plateau mountains are formed.
• Fault-block mountains emerge when boundaries between plates cause a block of land to rise high or fall low.(e.g: Harz mountains,Germany)

Today,to visit Inca civilizations,you will have to travel by train at dizzying height.The next time you eat "French"Fries,say "Thank You" to the ancient Incas of the Andes.
