100
Name four ways that crystals are formed.
What are
Magma and Lava
Solutions
Evaporation
Hot Water Solutions
100
is molten material from inside Earth that has hardens to form rock.
What is Magma
100
is a rounded, hollow rock that is often lined with mineral crystals. Crystals form inside the mineral.
What is a Geode
100
has a property to glow in ultraviolet light.
What is Fluorescence
200
Fredrick Mohs invented the test, that is the most effective for identifying minerals
What is Hardness
200
How do minerals form in Lava and Magma
What is
Minerals form as hot magma cools inside the Earth, or Lava hardens on the surface. When the liquid cools crystals are formed.
200
This can easily be observed as a physical property.
( hint- the easiest one to see)
What is color
200
is magma that reaches the earths surface. Lava Also forms rock when it cools and reaches Earth’s surface.
What is Lava
200
bends light to make double or alternate images.
What is Optical properties
300
Name all the simple crystalline structures.
What are
Cubic
Hexagonal
Tetragonal
Orthohormbic
Monoclinic
Triclinic
300
When elements and compounds are dissolved in water they leave a ____________, crystallizations occurs
What is a Solution
300
is the color residue that the mineral can leave behind when scratched against a white tile.
What is Streak
300
This means that it cannot form from minerals that were once part of a living thing.
What is Inorganic
300
depends on how many atoms are in its crystal arrangement.
What is Cleavage
400
If a mineral can easily split along a flat surface it has the property of ___________
What is Cleavage
400
Larger crystals are found where in the earth and why?
What is
Larger crystals are found deeper in the Earth because the rate of cooling deep in the Earth is slower…
The faster the Magma and lava cools the smaller the crystals are formed.
The slower rate that Magma cools the larger the crystals.
400
A term used to describe how light is reflected from the minerals surface.
What is Luster
400
is a naturally occurring, inorganic solid that has crystal structure and a definite chemical composition.
What is a Mineral
400
There is a variety of scientific ways to describe the fractured pieces.
What are Curved, chipped, splintered, jagged, rough and irregular
500
Describes how minerals look when they break apart in an irregular way.
What is Fracture
500
is a process by which atoms are arranged to form a mineral with a crystal structure.
What is Crystallization
500
The mass that is in a given space, or mass per unit of volume.
Please give the equation that is used also
What is Density
Density= Mass/Volume
500
List scientific adjectives to describe luster
What is Shiny, glassy, earthy, waxy, pearly, dull
500
some will react to acids and bases.
and (two part question)
attracts iron and other metals.
