How were the himalayas formed? a.) when a mid-ocean ridge split apart b.) when two plates collided with each other c.) due to an increase in volcanic activity d.) due to a sudden shift along a transform boundary

Himalayas are formed when two plates collided with each other.

Option B

Explanation:

Himalayas were formed when two plates collided with each other and these two plates were the Indian plate and the Eurasian plate. This collision of two plates began at least 50 million years ago and it continues even till date.

The sedimentary rocks which were known as the Tethys, which were settled in the depression in the crust of the surface of Earth changed their position, folded and this led to the formation of the huge mountain range known as the Himalayas.
