How were the Andes mountain range and the Himalayas formed differently?

Answer 1

They are both the result of plate tectonics. The Andes mountains are the result of plate tectonics when the so-called South American plate was forced upwards by two other plates covered by oceans that drifted under and into it.

The Himalayas formed when the Indian subcontinent drifted northwards and finally bumped into South Asia. The enormous mass of the Indian continent meant that on contact this drift did not immediately stop, but India kept forcing itself nothwards, forcing the earth before it up and 'folding' it into mountains. To this day this drift continues, at a pace of almost 7 centimeters a year.

Answer 2

The formation of the Himalaya and the Andes are similar because they are both are mountain ranges. The Himalayas and the Andes are different because the Himalaya is bigger than the Andes.

Answer 3

Two different types of tectonic plate convergence were involved. The Andes are a result of subduction involving the collision of an oceanic plate and a continental plate. The Himalayas are a result of uplift and crust thickening involving the collision of two continental plates.

Answer 4

The Andes mountains and the islands of Japan are both formed by subduction zones which was caused by volcanoes. The Himalayas were formed by convergent plate boundaries but no subduction zone. Instead the plates collided and there was uplift causing the mountains.
