Question

Which is not a process involved in the formation of sedimentary rock?

a:weathering
b:compaction
c:deposition
d:extrusion

Answer 1

Extrusion is NOT a process involved in the formation of sedimentary rock.

Answer 2

d:extrusion

Step-by-step explanation:

Extrusion has nothing to do with the formation of sedimentary rock, since it is a process of building objects with a defined and fixed cross section. The material is extracted using a die with the cross section to be made. This process allows the creation of complex cross sections with brittle materials, since the material only finds compression and cutting forces.
