Minerals & Properities
This mineral property describes the tendency of a mineral to break into irregular pieces?
What is FRACTURE?
This process describes how liquid magma becomes an igneous rock.
What is COOLING?
This sedimentary rock group forms from the remains of plants & animals.
Organic rocks
Metamorphic rocks are formed when sedimentary and igneous rocks are exposed to what kinds of elements?
What is HEAT & PRESSURE?
A scale that ranks minerals from softest to hardest.
Mohs Hardness Scale
The mineral Hematite leaves a reddish-brown powder behind when it is scratched along a surface. Identify the property being described.
What is STREAK.
This type of igneous rock cools slowly deep in Earth's surface and has well developed, large crystals.
What is AN INTRUSIVE IGNEOUS ROCK?
What processes take sediments and form them into sedimentary rocks?
What is CEMENTATION & COMPACTION?
This property of metamorphic rocks is an arrangement of minerals in flat or wavy parallel bands caused by rocks exposed to uneven amounts of pressure.
What is FOLIATION?
Mass per unit of volume
A mineral looks it is made of metal when light reflects from its surface. Identify the property that is being described.
What is LUSTER.
Identify the type of igneous rock that forms from lava and hardens on the outside of Earth.
Extrusive Rock
According to "Identification of Metamorphic Rocks", which rock type is most likely to be nonfoliated, have a coarse texture, be light in color, and fizz with the acid test?
What is MARBLE?
Element is composed of a single kind of atom and a compound is composed of two or more elements.
This property of a mineral refers to the mineral's ability to split easily along flat surfaces.
What is cleavage.
Identify the three processes that form igneous rock.
Melting, cooling, and hardening
Clastic rocks
Identify how a metamorphic rock would become a sedimentary rock.
Weathering/erosion/deposition/compaction/cementation.
An igneous rock texture that consists of larger crystals scattered on a background of smaller crystals.
Porphyritic rock
Identify the 5 characteristics a substance has to have to be considered a mineral.
solid, naturally occurring, inorganic, crystal system, and fixed chemical formula
According to "Identification of Igneous Rocks" which rock type is most likely to have fine grain size, be light in color and have many small bubbles?
What is PUMICE?
Identify the type of sedimentary rock group that form when minerals are precipitated from a solution or left behind when a solution evaporates.
What are chemical rocks
According to "Identification of Metamorphic Rocks", which rock type is most likely to show foliation, have a fine grain size, and a dark color, and being fairly soft?
What is SLATE?
Identify the three characteristics a that geologists use to classify rocks.
texture, color, and mineral composition.
