100
Which of the following is NOT a characteristic that all minerals have in common?
a) definite crystalline volume and shape
b) contains living cells
c)a unique chemical make-up

b) contains living cells
100
This mineral is known for its yellow crystals and rotten-egg smell.
Sulfur
100
What are the 3 types of rocks?
Igneous, Sedimentary, and Metamorphic
100
(Triple Jeopardy!) Which type of chemical weathering involves a reaction between water and carbon dioxide, easily dissolving limestone and marble?
Carbonation
200
(Triple Jeopardy!) What is the difference between weathering and erosion?
Both involve the breakdown of rock material, but erosion involves the movement of sediments.
200
(Triple Jeopardy!) What is responsible for the physical and chemical properties of minerals?
Chemical composition/atomic structure
200
(Double Jeopardy!) This mineral is known to glow in the dark, under exposure to UV light.
Fluorite
200
(Double Jeopardy!) What two factors can cause metamorphism to take place?
Heat and Pressure
200
Which type of mineral breakage is present in the photo below?
Cleavage
300
(Triple Jeopardy!) Which photo does not belong, AND explain why?
B; it shows chemical weathering, whereas the others are all physical weathering
300
Explain why color isn't always the most-reliable physical property to use in identifying minerals?
Some minerals come in multiple color variations, and some minerals share the same the color.
300
This element is present in magnetite and often in other minerals that display magnetic properties.
Iron
300
(Triple Jeopardy!) What is the difference between extrusive and intrusive igneous rocks?
Extrusive forms from cooled lava. Intrusive forms from cooled magma.
300
Name three ways minerals can be formed.
Cooling and solidification of molten rock, re-crystallization, and precipitation
400
What is the major ingredient usually involved in chemical weathering?
Water
400
(Double Jeopardy!) What is the name and range of the hardness scale used for minerals?
Moh's Hardness Scale; 1 - 10 (10 being the hardest)
400
This mineral is composed of the same element found in diamonds, but has a flat, layered atomic structure.
Graphite
400
What do you need in order to form sedimentary rocks?
Sediments
400
(Double Jeopardy!) Which type of rock is formed from the cooling and hardening of molten material?
Igneous
500
Which type of climate usually produces thick soil that is high in organic matter and low in mineral content?
Humid climate
500
(Triple Jeopardy!) What are the top two most-common elements found in the composition of minerals?
Silicon and Oxygen
500
(Quadruple Jeopardy!) This mineral was notoriously and mistakenly identified as gold during the 'Gold Rush' era.
Pyrite
500
What do you call sedimentary rocks that contain plant material?
Bioclastic Sedimentary Rocks
500
What was the original color of the Statue of Liberty?
Copper Red/Brown
