and organic matter.and organic matter.
2.2.Rock Cycle: Rock forms, changes Rock Cycle: Rock forms, changes
from one type of rock to another from one type of rock to another

6. H. Compaction and H. Compaction and
CementationCementation
Over time these deposited grains and pieces of
rock are compacted and cemented together
in layers.
The compaction and cementation occurs when
sediment is squeezed by the weight of the
sediment layers above it.
Each layer may be different from the next
layer depending on the type of sediment that is
deposited.

14. L. Intrusive Igneous RockL. Intrusive Igneous Rock
1. forms when magma is trapped deep inside
the Earth, cools very slowly over many
thousands or millions of years until it solidifies.
2. Intrusive igneous rock can be pushed to the
surface by plate movement.
3. Uplift pushes rocks to the surface.
