Answer: very tall mountain ranges
Explanation:When there is a collision between two continental plates, they become crunched up and then the rock folds at the boundary where it becomes lifted up and this leads to the formation of mountains and mountain ranges.
When collision occurs between two continental plates, both plates cannot be subducted because of their increased bouyancy. So when this collision occurs, features like subduction zone, trench and wedge do not occur. This type of collision occurs when the sea becomes narrower until both plates collide.
After the occurence of the collision, oceanic lithosphere breaks off and then sinks down into the mantle. The subduction zone then becomes inactive.
The two continents now welds together as they are being compressed together as time goes on.
The earth crust then becomes thickened by the under- thrusting of one continent under the other continent.
An example of this collision is the Himalayas where India collided with Asia.
