Which property categorizes minerals as either metallic and nonmetallic?
The property that categorizes minerals as either metallic or nonmetallic is their luster. Metallic minerals exhibit a shiny, reflective surface that resembles metal, while nonmetallic minerals have a dull, glassy, or earthy appearance. This distinction helps in identifying and classifying minerals based on their physical characteristics and potential applications.
How do vein minerals form?
Vein minerals are those that form in fissures in the existing rock, either thru deposition by mineral saturated hydrothermal fluids, or injection of magma and subsequent cooling.
What term used to describe how light is reflected from a minerals surface is?
Surface reflection is either specular or diffuse.
How can a bridge be made stiffer?
either different materials or a stronger base/structure
Is a mineral a gem or an ore?
Either, or both. Minerals are usually considered gems if they are valuable, attractive and highly pure. Minerals are considered ores if they are used to extract a substance. For example, pure haematite is polished and sold as a gem, while crude haematite is used to extract iron.
What is differences between texture and composition?
Composition is the chemical makeup of a rock and describes either the minerals or other materials in the rock, and, texture is the quality of a rock that is based on the sizes shapes and positions of the rocks grains.
Which process involves either a physical or chemical breakdown of earth materials?
Weathering is the process that involves the physical or chemical breakdown of Earth materials. Physical weathering involves the mechanical breakdown of rocks into smaller pieces, while chemical weathering involves the breakdown of minerals in rocks through chemical reactions with water, air, or other substances.
What is the difference between texture and composition?
BASCILY texture is feel of something an Composition is what does it take to make up something.Texture is based on the sizes, shapes and position of the rocks grains. The Composition of a rock is determined by the minerals that make up the rock. Composition and texture are two characteristics that scientists use to classify rocks.
What type of rocks are an accumulation of particles (either clastic or chemical rocks)?
Sedimentary rocks are formed from the accumulation of particles, which can be either clastic or chemical in nature. Clastic sedimentary rocks are composed of fragments of other rocks and minerals, while chemical sedimentary rocks form from the precipitation of minerals from solution. Both types result from processes like erosion, deposition, and lithification. Examples include sandstone (clastic) and limestone (chemical).
Is clay either homogeneous or heterogeneous?
Clay is heterogeneous because it is composed of various minerals and organic materials that are not uniformly distributed throughout its structure.
What is a solid formed in nature with a definite chemical makeup and crystal structure?
It is not obvious from your question whether you are asking for a term which describes solid materials having a definite chemical makeup - which would be a chemical or a substance, although those terms would apply equally well to liquid or gas materials having a definite chemical makeup - or whether you are asking for examples, which would include such things as ice, marble, table salt, steel, copper, etc.
Minerals like all matter are composed of elements?
That's correct. Minerals are naturally occurring inorganic compounds with a specific chemical composition, typically made up of combinations of elements bonded together in a crystalline structure. It is this unique composition of elements that gives minerals their distinct physical and chemical properties.
Which phrase best describes the electron transport chain in photosynthesis?
Yes. Photosynthesis involves the transfer of electrons. Photosynthesis causes a chemical change. All chemical changes involve either the transfer of electrons or a change in the configuration of electrons. No other way exists to make a chemical change.
What are the minerals found in the insulation of homes?
In the case of fiberglass insulation, it's silica, either from quartz or feldspars.
Can minerals be elements or compound?
They can be either. Gold and carbon are both elements that occur as minerals in element form. Carbon in fact takes two mineral forms: graphite and diamond. Most minerals are compounds. Some of the simpler ones include silicon dioxide (quartz), aluminum oxide (corundum), and sodium chloride (halite).
Are all minerals crystalline?
A mineral, by definition is an inorganic solid with a crystalline structure formed naturally. Wood, paper, or any other organic solids are not minerals because they have no crystalline structure and form organically. Plastic is not a mineral either because it is made synthetically out of organic materials. Some organic materials like coal and other hydrocarbons are considered minerals economically. Bones and teeth contain hydoxylapatite that is organically formed but is still considered a mineral, so there are exceptions. Whewellite is organically formed but has a crystalline structure, and is considered a mineral.
What best describes what happens in a chemical reaction?
atoms in substances react with eachother
