How do mountains get made? – Astrid, age 6, Marrickville

Hi Astrid. You may not trust this yet when I was about your age my educator (Mr Rouve) clarified for the class how mountains get made.

He took a piece of paper and placed it level on the table. Then, at that point, he put the tips of his right and left hands’ fingers on each side of the level sheet and gradually pushed his hands toward one another. Attempt to make it happen and you will see that the center piece of the paper will take off the table to frame a pleasant overlap.

My educator made sense of that mountains structure along these lines, when level layers of rocks are pushed toward one another they move up framing tall mountains.

My educator was truly energized by a revelation made by geologists around then, when I was a youngster. These geologists had sorted out that the outer layer of the Earth was, similar to a goliath jigsaw puzzle, made of pieces. Those pieces, called “structural plates”, move and catch one another.

This knocking makes seismic tremors, which gradually push the ground surface vertical to make mountains. It works out so sluggishly that, as a matter of fact, you are getting taller quicker than mountains do, with the exception of mountains save endlessly developing for a long time until they are so weighty they can never again become taller, just more extensive.

Truth be told, Australia and New Zealand are perched on two unique “structural plates” that move towards one another at the speed of a couple of centimeters each year. Where they catch one another, the ground gets lifted to frame the staggering New Zealand Alps, the highest point of which stands near 4,000 meters. Could you at any point envision around 4,000 individuals as tall as you, standing straight up on one another shoulders? That is the means by which tall these mountains are.

Mountains likewise structure when the World’s outside layer is pushed vertical from under. Simultaneously the New Zealand Alps began to shape, an enormous hot air pocket of rocks bringing from profound up in the Earth, similar to a goliath air swell, was pushing up the outer layer of the eastern piece of Africa framing a 4,000 meter high level. This level split to frame what is known as the East African Fracture, a valley two times the length of the New Zealands Alps.

There are numerous mountains at the outer layer of the Earth. A few we can see, a few we can’t on the grounds that they are under the ocean. On the off chance that you could take a submarine and jump under the ocean, for example in the in the middle among Australia and Antarctica, you could visit a long mountain where the Australian and Antarctica structural plates create some distance from one another.
