The Rock Cycle
This is a picture of the rock cycle. I found this picture on the internet.
This picture shows that metamorphic changes into sedimentary and then changes into igneous rock and then changes into metamorphic and then changes into sedimentary.
Metamorphic rock turns into sand to become sedimentary. Then to become igneous rock the sedimentary rock get subducted into the mantle. Then in the mantle the rock melts to become magma. Then the magma becomes igneous rock. Then igneous rock becomes metamorphic when it gets pressed together.

How Rocks Get Their Texture!
Well igneous rocks get their texture by the same way all rocks do. The 2 procedures are similar but still different. One way that a rock gets it's texture is if it is an extrusive rock that has been shot out of a volcano it will cool down and have fine crystals. It would be a fine grained rock. If the rock cools down inside of the earth it is going to cool slower and it will have fine large coarse grained rocks. They are different because of the speed and temperatures that they cool down at.
Uses Of Rocks
I found this website, where I found the uses of rocks here
The Stone Age lasted about 3 and 1/2 million years, This time is also known as the pre-historic times, This era ended about 4,000 to 6,500 years ago when people learned how to make metal, Obsidian and Flint were used to make the weapons, and river rocks were used to break other things, Caves were used as places to live and rocks and boulders were used to sit on and to build fire pits.
The Copper Age This is the age when humans learned how to smelt (melt using high heat) Copper Ore, In Britain, it was about 4,500 years ago and lasted for several centuries. This was not a long period because people learned quickly how to make other metals, during this time. Cities were being built and building stones were being used a lot.
The Bronze Age This age started about 6,000 years ago. Bronze is an alloy of copper. During this time, people learned how to mix minerals and produce other metals like Copper, Bronze, lead, and tin, by smelting ores together, Smelting Ore is when you melt crushed rocks with minerals in them at very high temperatures. By adding other chemicals and minerals the metals separate out the metal and can be poured off. Smelting is like melting with a purpose, The melted rock that is not metal is called slag
The Iron Age This age started about 3,000 years ago, During the Bronze Age they learned how to extract / make metal from rocks. During the Iron Age they learned how to make tools & implements (things they used) out of metal. Iron is very strong and made very good and long lasting tools. These tools also meant that stone could be shaped into more easily and many empires built building structures and roads that still can be seen today. Since that time period, people have built many cities and used minerals extensively.
Modern Age This age started 400 years ago, we have been using rocks and minerals at a increasing rates as we build machines, cities, and consume a great number of "things" in a lifetime. Our uses of rocks and minerals can be divided into 5 categories.
1. Building Stones
2. Machines & Tools
3. Artifacts
4. Consumables & Processes
5. Decorations
6. Jewelry

How Some Rocks Look Like
Metamorphic Rocks
Sedimentary Rock
Igneous Rock
Vocabulary
Igneous Rock : Rock formed by the solidification of molten magma.
Sedimentary Rocks : Rock formed from consolidated clay sediments
Metamorphic Rocks : Rock altered by pressure and heat
Texture : The feel, appearance, or consistency of a surface or a substance.
Fine Grained : Having a fine, or delicate arrangement of crystals.
Coarse Grained : Coarse in texture or grain (Coarse is rough or loose in texture)
Sediment : Matter that settles to the bottom of a liquid; Dregs. ( The remnants of a liquid left in a container, together with any sediment or grounds )
Compaction : An increase in the density of something.
Cementation: The binding together of particles or other things by cement.
Clastic Rock: A rock composed of broken pieces of older rocks.
Organic Rock : A rock that has been formed by living creatures.
Chemical Rock : Chemical sedimentary rocks are those rocks that are deposited from aqueous solutions and precipitation which may be caused by chemical or biochemical processes. They are grouped into carbonates, evaporites and chert.
