3. • Sedimentary Rock are formed by
Consolidation & Cementation of the sediments
deposited under water.
• Secondary Rocks
• Almost 75% of the earth crust is covered by layers
of sedimentary rock.
• Volume of sedimentary rock on the earth crust
is less than 10 %, i.e. ranging between 5 to 8
%

4. FORMATION OF SEDIMENTARY ROCK
The rock cycle shows the relationship
between the three types of rocks i.e.
igneous, sedimentary & metamorphic rocks.
The process of formation of sedimentary rock is
continues process.
 The existing rocks Produce sediments

5. FORMATION OF SEDIMENTARY ROCK
Three Stages of formation of sedimentary rocks are:
i. Weathering & Erosion of pre-existing rocks,
ii. Sedimentation,
iii. Lithification & diagenesis
