Explanation:

A landform refers to a geomorphic or natural feature of the Earth's surface, which typically makes its terrain. Some examples of landforms on planet earth are mountain, plains, valley, hills and plateau.

Basically, the tectonic plates such as the oceanic and continental lithosphere interact in three (3) ways and these are; divergent, transform and convergent boundaries.

A convergent plate boundary can be defined as a boundary where two (2) plates move towards each other, usually, resulting in subduction or collision. This action often causes mountain range such as the Himalayas to form by the collision between the plate carrying Eurasia and that of India; as a result of subduction which causes a plate to be forced underneath the mantle, deep ocean trenches are formed such as the Mariana trench.

Hence, Rift Valleys cannot form when two plates collide because they are formed only when the tectonic plates of earth rift or move apart. Also, Rift Valleys are found at the bottom of oceans and on land.
