Which option correctly describes the difference between a renewable resource and a nonrenewable source quizlet?
What is the difference between renewable resource and a nonrenewable resource?
renewable resources can be replenished over a short amount of time, nonrenewable resources take millions of years to replenish

Which statement best describes the difference between mineral cleavage and mineral fracture?
Mineral cleavage is the mineral’s tendency to break along flat, even planes, whereas
mineral fracture is the mineral’s tendency to break into uneven surfaces
.
What is a mineral’s cleavage quizlet?
Define Cleavage.
The tendency of a mineral to break along planes of weakness
. Define Fracture. When there is no cleavage, resulting in irregular masses with no flat surfaces. You just studied 4 terms!
What are the two most common carbonate minerals?
The most common carbonate mineral in soils is
calcium carbonate in the form of calcite
. Two other polymorphs of calcium carbonate, aragonite and vaterite, also exist; however, neither is common in soils.
What are the three components of Magma?
Magma and lava contain three components:
melt, solids, and volatiles
. The melt is made of ions from minerals that have liquefied. The solids are made of crystallized minerals floating in the liquid melt.
Is rain water a mineral quizlet?
Use the geologic definition of a mineral to determine which of the items listed are minerals and which are not.
Rain Water – No – Rain water is not a solid substance
, it’s a liquid. Quartz – Yes – It is naturally occurring & has crystalline shape. … The five samples are specimens of the mineral fluorite.
What happens when carbonate minerals are tested with weak acid solutions?
The Acid Test on Rocks. Some rocks contain carbonate minerals, and the acid test can be used to help identify them. … It will produce
a very weak fizz when a drop of cold hydrochloric acid is placed upon it
, a more obvious fizz when powdered dolostone is tested, and a stronger fizz when hot hydrochloric acid is used.
Which of the following is minerals?
Minerals are those elements on the earth and in foods that our bodies need to develop and function normally. Those essential for health include
calcium, phosphorus, potassium, sodium, chloride, magnesium, iron, zinc, iodine, chromium, copper, fluoride, molybdenum, manganese, and selenium
.
What does fracture mean in minerals?
Fracture, in mineralogy,
appearance of a surface broken in directions other than along cleavage planes
. … See also cleavage.
Do all minerals break the same way?
Each kind of mineral always breaks in the same way
, and this property can help identify a mineral. In fact, the way a mineral breaks is a better clue to its identity than are its color and luster. Calcite has cleavage.
How can you tell the difference between cleavage and fracture?
Fracture is the characteristic way a mineral breaks. The difference between cleavage and fracture is that
cleavage is the break of a crystal face where a new crystal face is formed where the mineral broke, whereas fracture is the
“chipping” of a mineral.
What are the two most important driving forces of metamorphism?
Pre-existing rocks undergo metamorphism when they are
subjected to heat and pressure without melting
. The presence of fossils in pre-existing rocks leads to the development of metamorphic rocks. Pre-existing rocks undergo metamorphism when they are subjected to heat and pressure without melting.
What are the two major categories of luster?
There are two main types of luster:
metallic and nonmetallic
. There are several subtypes of nonmetallic luster, namely vitreous, resinous, pearly, greasy, silky, adamantine, dull, and waxy.
