|
Minerals can be identified based on what two properties? |
Physical and chemical properties |
|
|
|
If a mineral is shiny like a new quarter, which physical property does it have? |
Luster |
|
|
|
What is a quick way to test the hardness of a mineral? |
The Mohs Hardness Scale |
|
|
|
What is cleavage? |
Cleavage is the property of a mineral that allows it to break smoothly along specific internal planes (called cleavage planes) when the mineral is struck sharply with a hammer. |
|
|
|
Which properties is the most useful in identifying a specific mineral? |
Hardness or color |
|
|
|
What determines a minerals physical properties? |
The atomic structure and crystal chemistry of the minerals. |
|
|
|
What kind of rock is formed when rock fragments are deposited and cemented together? |
Sedimentary rocks |
Cement sounds like sediment |
|
|
How are sedimentary rocks formed by compaction and cementation of land derived of land derived sediments classified? |
Pieces of rock are loosed by weathering, then transport to a basin where sediment is trapped. If it’s buried deep enough it will compact and cement and sedimentary rocks will form. |
|
|
|
What type of sedimentary rock is formed from particles sized less than 0.0004 cm? |
Silt and clay |
|
|
|
What are igneous rock formed from? |
The cooling or crystallization of magma or lava |
|
|
|
What determines the size of crystals in igneous rocks? |
If the magma cools slowly Then the crystals have enough time to grow and become large. |
|
|
|
If a rock cools very slowly underground, what size crystals will it have? |
Large crystals bc slow cooling equals large crystals |
|
|
|
A coarse grained igneous rock contains potassium, feldspar, quartz, plagioclase feldspar, biotite, and amphibole. What rock is it? |
Granite |
Think of how hard and coarse granite counters are |
|
|
What feature do metaphoric rocks have that the other rocks don’t? |
Less porous and less dense |
|
|
|
A sample of metaphoric rock is foliated, has medium to fine grain size, and has platy mica crystals visible from metamorphism of clay or feldspars. Which rock is it? |
Slate |
|
|
|
Limestone and marble both bubble when hydrochloric acid is placed on them. What would this indicate? |
Because carbon dioxide is released because the rocks have the mineral calcite. |
|
|
|
Which mineral is commonly found in granite? |
Quartz |
|
|
|
Which common mineral fizzes when dilute hydrochloric acid is placed in it |
Calcite |
|
|
|
Which type of sedimentary rock is formed from the compaction and cementation of pebble size particles? |
Conglomerate |
|
|
|
Which characteristics are common in sedimentary rocks? |
Foliation and layering |
|
|
|
Which sedimentary rocks are formed by evaporation of water? |
Chemical sedimentary rocks |
|
|
|
Which class of rocks contain fossils? |
Sedimentary rock |
|
|
|
What is a mineral? |
A naturally occurring element or compound that is inorganic and crystalline in structure |
|
|
|
The property of minerals is determined by? |
Internal arrangement of atoms |
|
|
|
The property of minerals is determined by? |
Internal arrangement of atoms |
|
|
|
Can a mineral scratch any mineral that has a hardness equal to itself? |
Yes! |
|
|
|
How are rocks categorized? |
Based on how they formed! |
|
|
|
What is texture of a rock? |
Size and shape (NOT how rough it is) |
|
|
|
What is rock cycle? |
Rocks are formed, broken down, and reformed in a cycle |
|
|
|
Recap of three rocks. Sedimentary rocks are? |
Rocks formed by mineral deposits (sediment deposits). Have fossils in them. Ex: shake, limestone |
|
|
|
Recap or three rocks! Igneous rocks are? |
Formed by cooling and solidifying of magma or lava. Example: Granite! Think IGneous And G for Granite! |
|
|
|
Recap of three rocks! Metamorphic rocks are? |
Started out as other rocks and due to high heat and high pressure the broke down and reformed as metamorphic rock. examples: Marble! Gneiss! Slate! |
