The rock style
The three main types of rocks – igneous, sedimentary and
metamorphic– are created in different ways, and can each be used to
form another kind of rock e.g. sedimentary rocks under high pressure will
The makeup of the Earth is constantly changing and this contributes to it.
If we begin from newly formed igneous rock, we can the rise a possible rock
cycle. Lava or magma will cool, forming the igneous rock. If there is
weathering or erosion, little pieces of that rock may break off and eventually
become deposited in the river somewhere.
Through documentation and compaction, these little pieces of rock may
eventually become sedimentary rock.
The sedimentary rock may become exposed through uplift and also undergo
weathering/erosion to form different sedimentary or it may become pushed
further into the Earth.
Under intense heat and pressure, while it is underground, the sedimentary
rock could turn into metamorphic rock. This could also happen to igneous
rock if it is pushed underground.
