In what ways are the sierra nevada mountains and the andes mountains the same in terms of mountain formation?

hi

Explanation:

First the are both in America, Sierra nevada in North america and the Andes in South america.

Fold mountains  

These are the most common type of mountain. As two plates move towards each other they buckle and the crust pushes upwards, forming a mountain. Fold mountains are generally formed between 40- 50 million years ago, which is geologically-speaking, young. They are often high with steep faces. Examples of fold mountains include The Himalayas, The Andes, The Rockies and The Alps.

The Andes: The Andes Mountains are located in South America, along the western coast of the continent and stretch 7000 km. They extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina.The highest peak in South America, at 6962 metres, is Mount Aconcagua, which is part of the Andes range. The Andes were formed when the Nazca plate collided with the South American plate.

Fault block mountains  

These are formed when two plates move towards each other. Rather than the crust folding under the pressure of the moving plates, it cracks along lines of weakness called fault lines. The crust then breaks into blocks, which are pushed upwards.  

The Sierra Nevada: An example of fault block mountains is the Sierra Nevada mountain range in California, USA. The range is located in eastern California and stretches for 640km. The highest peak of the Sierra Nevada is Mount Whitney, at 4418 metres. The mountains are primarily composed of granite. The Sierra Nevada range was the site of the American gold rush in the 1840s.
