The Rock Cycle
![Page 2: The rock cycle](https://reader036.fdocuments.in/reader036/viewer/2022081602/556ea70cd8b42afe778b4cb1/html5/thumbnails/2.jpg)
What is the rock cycle?
• It is a model that shows how closely related all the different types of rocks are to each other. – The amount of rock
material on earth remains the same
– However, the rocks go through many different transformations
![Page 3: The rock cycle](https://reader036.fdocuments.in/reader036/viewer/2022081602/556ea70cd8b42afe778b4cb1/html5/thumbnails/3.jpg)
How does the rock cycle work?
• Form sedimentary rocks• Igneous is known to be
the primary (parent) rock on earth. – As the rocks come into
contact with weathering and erosion , pieces break off
– These pieces get transported and put together to form sedimentary rocks

Form into Metamorphic Rocks
• If these rocks or the igneous rocks are exposed to huge amounts pressure and heat they form into metamorphic rocks

Form into Igneous rocks
• If the metamorphic rocks or the sedimentary rocks melt and form into magma then they create igneous rocks

General Rule !!!
• ANY TYPE OF ROCK CAN FORM INTO ANY OTHER TYPE OF ROCK AS LONG AS IT IS SUNJECT TO THE RIGHT CONDITIONS

Proof #1 of the rock Cycle
• When we look at a sedimentary rock carefully – We see particles of all
types of rock and from all over the place

Proof of the Rock Cycle
• When we look at other types of rocks we can see that the rocks have gone through many different changes.

How are the rocks used?
• Igneous – Granite for example is
used to build monuments etc……
– Might be crushed and used for roads etc…

• Sedimentary – Especially sandstone
is commonly used in construction and building houses and buildings

• Foliated metamorphic rocks – Can be cut and used
for roofing
• Non-foliated (like marble0 is great for making statues etc…

Introduction
• The Earth’s population is growing by the second – Therefore the demand
for energy and products has rapidly increased
– What is the problem and solution ?

Fossil Fuels
• Right now fossil fuels is the primary source of our energy– Fossil fuels include
• Coal• Oil • Natural gas
– They are non-renewable sources because we use too much too quickly

What can we do?
• We can use alternative energy – Solar – Hydropower (water
powered)– Wind– Wave– Nuclear energy – These do less harm to
the environment than fossil fuels

The 4 Rs
• Reduce – We can reduce how much
fule we use• Reuse
– We what we used already• Recycle
– Use materials that can be recycled into new
• Paper into recyclable paper
• Reclaim – We can collect and use
what has already been thrown out
