I learned that the Feldspar is a mineral that is used in kitchen tyles.
What is the difference between rocks and minerals?
A mineral is a solid formation that occurs naturally in the earth while a rock is a solid combination of more than one mineral formation which is also occurring naturally.

Quartz
By Abdiel Mendoza
Quartz is a rock that use into a jewel. The quartz is made by crystal and rock. The quartz found in mountains is the second abundant rock in the word and is a rock that is in the granite always the quartz are hard, triangle, circle, square and is a expensive mineral.
ROCKS AND MINERALS
QUARTZ
First the Quartz is very beautiful and useful. It could be of color white, pink or purple. The shape is rectangular, triangular or like a square. Next the texture could be soft, rough or hard and the size could be small, medium or big. Finally the Quartz is used for jewels or other things. The different between a rock and a mineral is. A mineral is a solid formation that occurs naturally in the earth while a rock is a solid combination of more than one mineral formation which is also occurring naturally.
Travertine
By :Ernesto
Guizado
The travertine come from an old town of Italia named tibu, his name come from the finder Lapis Traburtino, in the river Tibur. This is a rare rock that absorb water.
Characteristics:
Color: cream
Shape: rectangular
Type: Travertine
Granite
Granite is a common and widely occurring type of intrusive, felsic, igneous rock. Granites usually have a medium- to coarse-grained texture. Occasionally some individual crystals phenocrysts are larger than the groundmass, in which case the texture is known as porphyritic. A granitic rock with a porphyritic texture is sometimes known as a porphyry. Granites can be pink to gray in color, depending on their chemistry and mineralogy. By definition, granite is an igneous rock with at least 20% quartz by volume. Granite differs from granodiorite in that at least 35% of the feldspar in granite is alkali feldspar as opposed to plagioclase; it is the alkali feldspar that gives many granites a distinctive pink color. Outcrops of granite tend to form tors and rounded massifs. Granites sometimes occur in circular depressions surrounded by a range of hills, formed by the metamorphic aureole or hornfels. Granite is usually found in the continental plates of the Earth's crust.The average density of granite is between 2.65[1] and 2.75 g/cm3, its compressive strength usually lies above 200 MPa, and its viscosity at standard temperature and pressure is 3-6 • 1019 Pa•s.[2]
Conglomerate
The shape is triangle.
The color is black.
The texture is clastic.
The size is 2.2. M.M.
The type is sedimentary rock.
This rock is in someone places like constructions, in the earth and in others places.
The rocks and mineral
Almost all minerals are solid (except water, mercury, and opal). They have definite atomic structure and chemical composition.
Example: If you have two quartz crystal, they would have similar chemical and physical properties. To identify a mineral, you can observe its color, luster, hardness, specific gravity and streak . Fracture and cleavage may be obvious, or you may have to break the mineral.
The rocks are classified into three major groups - igneous, metamorphic, and sedimentary. Rocks are aggregates of different mineral, which are fused, cemented, or bound together. Rocks can be identified using the same methods as minerals .
Minerals and rock
Are many minerals and rocks but what is the difference?
The difference is that a mineral is a solid formation that occurs naturally in the earth
And the rock is a solid combination of more than more mineral formation which is also occurring naturally.
Feldspar is a common raw material used in glassmaking, ceramics, and to some extent as a filler and extender in paint, plastics, and rubber.
Characteristics
This rock have color pink and yellow This feldspar have a triangle form I found it in the beach
GOLD
Characteristics:
Mineral: Gold
Color: Golden (variety of orange-yellow color)
Luster: Shiny is a metal
Streak: Yellow streak
Hardness: 2.5
Other: Ductility and malleability
Gold is one of the most popular and well-known minerals, known for its value and special properties since the earliest time.
To day I know about the limestone that is a sedenmentary rock and he have many minerals and he effervence with acid.
to day I know about the iron is a mineral that use very much
Today I learn that a copper is a mineral and also that the copper is a very useful mineral that can be use to decorate the house.
I learned that the rocks and minerals there are different that the rock that i find is the Pumice that is a rock of the volcano this rock is in the penninsula of Jalisco in Italy and the other is in Guadalajara in Mexico.
this is a white color or a gray or black.

I leard so much in this project from the aluminiumn
Limestone
Maria Lucia Lum
I learn that look for rock is not easy but it values,I learn that the limestone is easy to find in gardens and is naturally cream oh and it is a rock not a mineral
my rock is a pumice i like. this rock lotate in a volcan baru an i like
today I is very happy because I teach to my friends about the coral rock. I want to teach also the other person, the coral rock is a rock of the water for example I use this rock from the tank the color is white etc.
I learned that there are three tipes of carbon.the c12 and the c13 are normal but the c14is radioactive so if you find a carbon number 14 do not touch it.
I learned that the quartz can be found in rivers he is like color cream is mineral and can decorate
the name of my of my rock granite THIS ROCK IS VERY ELEGANT HE USE FOR DECORATE THE HOUSE THE ROCK COLORS IS WHTE
I learned for my rock this rock contruction house and ect.The rock
is used in contruction of secretion of the sidestion is blank of sidection Riverert of rivert dry wells Quierra
The rocks are very important for the earth .The sea rock is rock of the ocean my rock are 4 characteristic
for example.1 the color is:gaer or yellow.Are the project is exelent are see rock are so mouch exelent.
"I Love SCIENCE"
I learned that the flagstone is a sedenmentary rock and is color red and others colors
My rock is amineral the colorb is red in my hause in the floor steat the rock.
I learnd taht the the Mica of to colors silver an brown is a good combination . This rock i find in a river but you can fin in others place like the ocean.
