Transcript Rock Cycle

Rock Cycle
By: Aaliyah Padilla
There are rocks all around us! All of the rocks that
can be found on Earth fit into three main categories.
 Igneous
Rock
 Sedimentary
Rock
 Metamorphic
Rock
Igneous Rock
1.The igneous rock can form on top of Earths surface.
A. Lava erupts onto Earth's surface.
B. This is called extrusive rocks.
C. Forms much of the Earth’s crust.
2.Igneous rock can also form beneath Earth’s surface.
A. Magma hardens beneath Earth’s surface.
B. This is called intrusive rocks.
C. Forms inside of many mountain ranges.
The Latin word ignis means fire
Sedimentary Rocks
Sediment: small, solid pieces of material that come
from rocks or living things.
1.Most sedimentary rocks are formed through
many processes.
2. These processes are: Erosion, Deposition,
Compaction, and Cementation.
3.Erosion:Moving water, wind, or ice loosen and
carry away pieces of rock.
4.Deposition: The water, wind, or ice slows down
and deposition the sediment in layers.
5.Compaction: The piece of sediment that get
pressed together.
6.Cementation: Dissolved minerals glue particles
of sediment together
Metamorphic Rock
1.A metamorphic rock is a rock that has changed its
form.
a. Meta means change
b. Morphosis means form
2.Two things that can change a rock:
a. Heat
b. Pressure
3. Collisions between Earth’s plates can push the
rock down toward the heat of the mantle.
4. Pockets of magma rising through the crust also
provide heat that can change rocks.
