Rocks and Minerals

Parent Category: Geology
A rock is a compound composed of two or more minerals. It is classified into three types based on how it is formed – igneous, sedimentary and metamorphic. Meanwhile, a mineral is grouped in classes based on its chemical properties.

It's not really possible to answer that, as there are so many. Itis also dependent on your definition of mineral. Some are quartz,feldspar, and horneblende.
No, she died in the camps.
Is a zapato a animal
There are four main processes that contribute to erosion - Chemical Weathering, Biological Weathering, Exfoliation, andFreeze-Thaw
It depeneds on the pebble
Igneous Rock,Sedimentary Rocks,Metamorphic Rocks Igneous made from cooled magma Sedimentary made from sediments Metamorphic made from either sedimentary or igneous
"Sedimentary rocks such as limestone can be used for a variety of purposes including highway construction and building stones, and, in the classroom, as chalk. Rocks such as coal and oil shale can be processed for their valuable, energy-containing carbon compounds. Rock gypsum can be ground up and...
Clastic rocks are made from fragments of pre-existing rocks.
Yes, clay is more porous than sand. Typical porosity of silt and clay is 35-50% and 33-60%, respectively. Sand has porosity of 20-35%.
Not unless they have grit and stones trapped in the tire treads.... But metals start out as minerals, and most bikes are made from metals.
They date the igneous intrusions and extrusions near the sedimentary rock layers.
Sediments harden to form sedimentary rock through the application of pressure. Heat may play a part, but it is the settling down of the sediment and the buildup of overburden that "crushes" the material together. After millenia in a "big squeeze" applied by zillions of tons of material that has been...
Thacher, right, well she wanted to shut down mines and put miners out of employement for no reason, and then set up Orgreave so she could beat them with violent police.
\nyes, metals are lustrous in nature.
Iron Pyrites? That would be Gold. Iron pyrites is known as "Fools Gold" Since it is similar to real gold nuggets in appearance.
You need a book for the answer ! Each gemstone has a long list of physical and chemical properties. For some details see the link below.
Depending on which company you buy them from, they are primarilystainless steel. Not carbon steel. Stainless doesn't rust and it ismuch cheaper for both the buyer and the manufacturer.
Each gem (or mineral) has specific chemical and physical properties. For detailed informations consult the link bellow.
Grog is the material usually added to clay to minimize shrinkage.Grog is ground fired clay and it adds strength to the body as wellas minimizing shrinkage.
Basalt is a commonly extrusive volcanic rock. It is usually grey to black and fine-grained due to rapid cooling of lava at the surface of a planet. Unweathered basalt is black or grey. Basalt is defined as an igneous rock that contains less than 20% quartz and less than 10% feldspathoid and...
Well, many sunglasses carry many kinds of minerals depending on the type of brand they are, and from where they are from. If you want a general answers, the majority of sunglasses contain about 25% or 40% nickel. As I said, its all pending on where they're from and who made them.
Rocks that are categorized as sedimentary rocks include sandstone,breccia shale, limestone and selenite. Sedimentary rocks areclassified by their grain size.
they never but never look at the color. so they put a black light on it so if it shines there get closer to know if it is a mineral. also if it has radio activity. :)
i think its the rock cycle im not sure hope this helps ......i guess 2012 :)
Sheetrock is primarily gypsum, combined with sand and water.
Whether it was fast crystallization - smaller Crystals or slow crystallization - bigger and finer Crystal forms!
Color can change in a mineral when in certain temperatures
The main source of interior heat in the Earth is radioactive decay. Some think the major current source is potassium, but in the past it was the trans-urantic elements - esp those with "short" half-lives.
Sodium and chlorine: the formula unit of sodium chloride is NaCl.
Some of the minerals that are found in food are calcium, fluorine, iodine, iron, phosphorus, sodium and zinc. These are all the ones that were spoken about in the class I am taken, so there may be more than this, but these are the basic ones that I know about. I hope that this can solve your...
It is OK, rubies are easy to make artificially as they are made outof Aluminium Oxide. However there is one particular gem mineral(Spinel) that looks like ruby and some of the world's most famousrubies are not rubies but Spinels. eg. the Black Prince's Ruby andthe "Timur ruby" in the British Crown...
The Shale is not a metamorphic rock it is a sedimentary rock.
yes, it is one of the most visible crystals in granite.
The subsoil becomes rich in minerals as minerals from the topsoilleach down into the subsoil.
Texas is a state with large land mass. It is rich in naturalminerals. Some of these minerals are: Barite, Beryllium, Bismuth,Celestite, Coal, Clay, and Copper.

rock hard..this was my homewrok too..thats what i guessed!!. ROCK SALT
They may be called "ores" but the term includes other minerals thatcontain valuable elements that are not metals.
how many vitamins and minerals and average
Often, but not always! The definition of a fossil is a whole, part or impression of an organism from a past geologic age, embedded in natural materials, such as rock, sediment, resin, petrified bones, or wood.
Hematite is an oxide of iron in its "raw" or "natural" form. It's a mineral, and it's iron(III) oxide. Its formula is Fe 2 O 3 . Hematite is Fe2O3.
Lead is a metal. The main lead mineral is galena (PbS), which contains 86.6% lead.
THE 4 special mineral properties are inorganic, solid, naturally formed, and compound
The faster the rate of cooling the smoother the rock will be.The slower the rate the more rough the texture. The faster it cools the finer the texture of the rock. Slowercooling magmas tend to form courser grained igneous rocks. The moretime a magma has too cool, the larger the crystals will be If...
This type of sedimentary rock must have organic material to be created. They are called organic because they are made from organic material such as grass or plankton that, over long periods of time, becomes a type of sedimentary rock. This organic material can be the organism itself or may be given...
Answer . Replace the wax ring with a double wax ring and shim the porcelain at the floor with plastic wedges, available at any home improvement store.
No, Chlorophyll is organic in nature.
It depends on the type of rock in question: Igneous; Metamorphic or Sedimentary. As an example, consider the differences between applying high temperatures to a volcanic rock and say, sandstone. Igneous rocks are born of primordial fire, so you'd think they could handle the minor heat of boiling...
Granite tables in the kitchen.
Sedimentary, Igneous and Metamorphic.
Marble is used principally for buildings and monuments, interiordecoration, statuary, table tops, and novelties. Color andappearance are their most important qualities. Resistance toabrasion, which is a function of cohesion between grains as well asthe hardness of the component minerals, is...
When the tension (stress) is great enough, they will fracture or deform.
Pyrite is iron sulfide often found metamorphic rock, quartz veins,and sedimentary rock. It can also be found in coal beds and fossilsas well as gold for which it is often mistaken.
Not exactly. Most metamorphism occurs deep underground. Some also occurs near the surface, but often with different results. There are two types of metamorphism: . Regional - This is very large scale, occurring at high pressure and high temperature. This causes mass transformation. The results are...
A rock is made of 2 or more minerals, minerals make up rocks but rocks cannot make up minerals.
Pumice is formed when lava cools very quickly ABOVE ground. The vesicles or tiny holes all over are formed when heavy amounts of gas escape from the lava while cooling, leaving those air pockets. Even though it doesn't seem like it, pumice has a glassy texture just like obsidian glass, both of which...
Pumice is formed near and above volcanoes from foamy lava that hasbeen ejected.
Uniformitarianism regards the strict adherence to set ofprincipals, regulations, appearance and rules of conduct.Uniformitarianism is a guiding characteristic to professionalmilitaries to ensure compliance, standardization and as a measuretowards discipline.
Diamond (and element - carbon) Gypsum (a sulphate) Calcite (a carbonate) Galena (a sulphide) Corundum (an oxide) Halite (a halide)
Galena and cinnabar are both sulfide minerals, and found around theworld. Galena is the natural form of lead and easily smeltedbecause of its low melting point.
It's useful to know a rocks texture because then you may identify all stones better
Both minerals and vitamins help enzymes perform their functions during metabolism. Without minerals and vitamins, hormones would be innefective. The requirement of mineral elements in the body is very varied. I'll show you a table below which explains in simple terms what I mean:. STRUCTURE: The...
Two methods for the preparation of salt in laboratory are: - 2Na + Cl 2 = 2NaCl - NaOH + HCl = NaCl + H 2 O
More concentraions of the minerals elements are located towards the center. Also light bleaches some of the color
A chemical sedimentary rock, such as rock salt or rock gypsum.
ORGANIC SEDIMENTARY ROCK`s : Is a type of sedimentary rock because sedimentary rock has three types of sedimentary rock called clastic , chemical , and organic sedimentary rock so yes ORGANIC SEDIMENTARY ROCK is a type of sedimentary rock..........................................
Uranium is not a mineral, but a chemical element; uranium is found in approx. 200 minerals.
Gold, silver, and copper are mined in Utah and zinc is a by-product, so yes it is mined in Utah.
The minerals beneficial to the human body are: sodium potassium chloride calcium phosphate sulfate magnesium iron copper zinc manganese iodine selenium molybdenum
The cleavage of mica is perfect. Sometimes it has parallel parting.The cleavage laminae is flexible and elastic. The thin translucentsheets allow geologists to view the metamorphosis.
Yes. A mineral resource is potentially valuable and reasonableprospects exist for eventual economic extraction. A mineral reserveis valuable and legally, economically, and technically feasible toextract.
A mineral is naturally occurring inorganic matter. a rock is 2 or more minerals combined
Double refraction is when you can see through a mineral and it shows two images instead of one. Calite is the mineral that exhibits it. I linked a great website for this kind of stuff below.
As in what process causes this? if so it is usually under heat and pressure. Depending on what kind of rick it is depends on the resultant metamorphic rock e.g Shale-->Slate etc
erosion but it would take thousand of years
Turquoise occurs in sedimentary or metamorphic rocks near or at the contact with igneous intrusives.
fools gold also know as iron sulphide FeS 2
In order to decrease the pressure within our respiratory tract, we have to expand our container. Our container is basically our thorax. If we can expand our thorax, the air pressure within our thoracic cavity will fall, and air will rush into our respiratory tract. The diaphragm is our primary means...
