i) - Particles are derived from existing rocks through process of weathering /Erosion.
- They are then transported by water/wind/ice and are deposited on land/large water bodies.
- They are deposited in layers.
- Over a period of time, they are compacted by pressure to form rocks such as a cluvial, clay,
sand, conglomerates.
ii) - Minerals are dissolved from land and are carried in solution into bodies such as
cakes/sea.
The mixing of water of different types may result in chemical reactions followed by precipitation leading to accumulation at bottom of water body and are compressed into a rock OR
Dissolved minerals can also be precipitated directly from water through evaporation.
This happens in very hot regions where there are constricted/shallow bays of lakes/seas ,such rocks are known as evaporates.
