THE ROCK CYCLE PROJECT
By Armando Lozoya Period 3 Ms.Armstrong
THE THREE QUESTIONS
• 1Q: How do plate tectonics affect the rock cycle? Make sure you explain all three
motions for plates. (Divergent, Convergent, and Transform)
• 1A: The plate tectonics are what power the rock cycle, without plate tectonics there
would be changes in the production and destruction of all three rock types. This was
found in the websites
www.windows2universe.org/earth/climate/geosphere_plate_tectonics.html
• 2Q: What other cycles do you know that are continuous and change one thing into
another
• 2A: Another cycle that is continuous and change one thing to another is the water
cycle. The reason why it’s the water cycle is because it is continuous and changes one
thing to another. (water to clouds then back to water its continuous)
• 3Q: Does the rock cycle have a beginning or an end? Explain your answer.
• 3A: No it doesn't have an ending or a beginning because it is a series or repeating steps.
Even if the rock dies out, it'll change to a new type of rocks, and then repeats over and
over again. No ending, no beginning, that's why it's called 'cycle. The word cycle is what
proves why the rock cycle has no beginning or ending.
THE ROCK CYCLE PICTURE EXAMPLES
SEDIMENTS AND SEDIMENTARY ROCK
• The main thing about sedimentary rocks is they used to be sediments, which
were mud, sand, gravel, and clay.
• Sedimentary rock is the second great rock class
• Sediment is arranged in layers of sandy or clayey material which is called
strata
• The color of sediment is light brown and light gray
• Sedimentary rock may preserve signs of life and surface activity, like fossils,
tracks, ripple marks and so on.
• Sediment comes from all three types of rocks igneous, metamorphic, and
sedimentary when they break apart they end up turning into sediment and
the cycle starting over again. The Rock Cycle
• There are three types of sedimentary rock: Clastic Sedimentary Rocks,
Organic Sedimentary Rocks, and Chemical Sedimentary Rocks
IGNEOUS ROCK
• Igneous rocks are formed when magma (molten rock) cools and solidifies, either on the
surface of the Earth, or beneath the Earth's crust.
• Igneous rocks are categorized into two groups: extrusive igneous rocks and intrusive
igneous rocks.
• When magma comes to the surface of the Earth as a result of some volcanic activity
and solidifies to become a rock, this rock is referred to as an extrusive igneous rock.
• When magma seeps in between the layers of sedimentary rocks beneath the crust and
solidifies to form a rock, it is referred to as an intrusive igneous
• Intrusive rocks are also known as Plutonic rocks after the Roman god of the underworld:
Pluto.
• Two examples of igneous rock are basalt and granite. Mainly there are over nine
hundred different types of igneous rocks that have been discovered by scientists
• Basalt (known as an extrusive rock) and granite (known as an intrusive rock) are two of
the most common igneous rock types on the Earth, and cover most of the igneous
deposits on the planet. Usually, the rocks in deep ocean floors are known to be basaltic
in nature, while the rocks in the continental mass are granitic in nature.
METAMORPHIC ROCK
• Metamorphism is a geological process involving rocks changing their form.
The process requires millions of years in transformation.
• Earlier, the transformed rocks could either have been igneous, sedimentary,
or even older metamorphic rocks.
• The heat and pressure of the Earth's crust bring about profound changes in
terms of physical as well as chemical properties, and give new textures to
the rock.
• The new texture that develops is through the process of recrystallization. The
texture and the kinds of minerals they consist of are how these rocks are
classified.
• Most classifications of metamorphic rocks involve first separating the rocks
into two categories by their texture -foliated rocks and non-foliated rocks.
EROSION
• Erosion is the gradual wearing away of rock or soil by physical breakdown,
chemical solution, and transportation of material
• Examples of erosion is water, wind, or ice.
• When there is a crack water would go into the crack and freeze inside the
rock cause the rock to split apart.
• Erosion is a important part of the rock cycle without it there would be no
such thing as a rock cycle
