Collision boundary

Question 2

When two continental plate boundaries meet

Answer 2

both may fold and deform; e.g. the Himalayas are formed by the collision of the Eurasian and Indian plates

Question 3

At a collision boundary two plates of similar density move towards each other

As neither plate can sink into the denser rocks below, they are

Answer 3

they are crushed, crumpled and forced upwards, usually folding in the process
This creates collision fold mountains such as the Himalayas, which are still being formed upwards,

at a rate of 1cm/annum

Question 4

As there is no subduction, there is no

Answer 4

As there is no volcano subduction, there is no

Earthquakes are the main hazard at this type of plate boundary
