Answer:
Yes, water helps in breakdown of bigger rocks into
smaller mineral particles by following methods
(i) Firstly, water could get into cracks in the rocks formed
due to uneven heating by the Sun. If this water freezes, it would cause cracks
to widen.
(ii) Secondly, flowing water wears away even hard rock over
long periods of time. Fast flowing water often carries big and small particles
of rocks downstream.
These rocks rub against the other rocks and resultant abrasion
causes the rock to broken down into smaller and smaller particles. The water
then takes these particles along with it and deposit them further down.
