Rock and Mineral Unit Major Concepts
Question | Answer |
---|---|
What are rocks made of? | Rocks are made of minerals. |
The type of mineral determines this... | Properties of the mineral. |
A mineral with a hardness of 3, can only scratch minerals with a hardness ... | less than 3. |
A mineral with a hardness of 7 can only be scratched by minerals with a hardness of... | greater than 7. |
We test the property of hardness with this scale. | Moh's Hardness Scale |
What do we mean when we describe something as synthetic? | This item is not natural. It is manufactured or manmade. |
All Rocks can become... | All Rocks. |
We determine what type of mineral we have by looking at this type of data. | Data from property tests will tell us what mineral we have. |
When we describe how rocks change over time we are really describing this. | The Rock Cycle |
What are the 3 words we use to classify how rocks are formed? | Igneous, Sedimentary, Metamorphic |
The heating and cooling of magma or lava forms this type of rock. | Igneous |
The extreme heat and pressure deep inside the earth forms this type of rock. | Metamorphic |
Tiny bits of weather rock that are cemented together by pressure form this type of rock. | sedimentary |
fossils can be found in this type of rock. | sedimentary |
This type of rock does not have fossils because of the melting and cooling process that creates them. | Igneous |
This type of rock does not have fossils because of the extreme heat and pressure deep in the earth that forms them. | metamorphic |
Luster is how shiny a mineral is and can be described by one of these 3 words. | Brilliant, glassy, dull |
Transparency is how well we can see through a material and can be described by one of these 3 words. | Transparent, Translucent, Opaque |
Light refraction can be determined if you see this when looking through the mineral at a printed line. | You will see a double image. |
