Metamorphic Rocks
Miscellaneous
100
TRUE OR FALSE: The rock cycle shows that any rock at Earth's surface can go through weathering and erosion.
What is TRUE?
100
The texture of an igneous rock that cools so quickly mineral grains do not have a chance to form.
What is glassy?
100
The geologic process that turns sediments into sedimentary rock.
What is LITHIFICATION (compaction and cementation)?
100
The geologic processes that change rocks into metamorphic rocks.
What are HIGH HEAT AND PRESSURE?
100
TRUE OR FALSE: Rocks are ONLY made of minerals.
What is FALSE? (Rocks can also be made of other rock fragments or organic material)
200
TRUE OR FALSE: The rock cycle shows that any rock can directly become an igneous rock.
What is FALSE? (Rocks need to melt into magma or lava first!)
200
The texture of an igneous rock that has holes in it.
What is vesicular?
200
The classification of a sedimentary rock that is made from plant fragments.
What is ORGANIC (or BIOCHEMICAL)?
200
The type of metamorphism that occurs when a rock is exposed to heat or chemically active fluids.
What is CONTACT METAMORPHISM?
200
Ms. Lorenc's favorite rock is named this.
What is PUMICE?
300
The processes represented by arrows 3 and 4.
What are heat and pressure? (or metamorphism)
300
The geologic processes that forms an igneous rock.
What are cooling and crystallization (solidification)?
300
The process where sediments are "glued" together with substances that are dissolved in solution, such as water.
What is CEMENTATION? (water with minerals dissolved in it move through rock fragments. The minerals stick to the sediment and "glue" the pieces together)
300
A metamorphic rock that has layers or banding is classified as this.
What is a FOLIATED metamorphic rock?
300
Acid rain is an example of this.
What is CHEMICAL WEATHERING?
400
The processes represented by arrows 5, 6, and 7.
What are weathering and erosion?
400
The classification of an igneous rock that forms from lava that has an even mixture of silica and iron & magnesium and crystals that can be seen with a magnifying lens.
What is EXTRUSIVE, FINE-GRAINED ANDESITIC rock?
400
Frost Wedging is an example of this.
What is MECHANICAL WEATHERING?
400
The THREE agents of metamorphism.
What are HEAT, PRESSURE, and CHEMICALLY ACTIVE HOT FLUIDS?
400
The effect that mechanical weathering has on the surface area of a rock.
What is it INCREASES surface area?
500
The processes represented by arrow 8.
What are compaction and cementation?
500
An igneous rock that forms from magma that has a greater amount of silica than iron & magnesium is classified as this.
What is an INTRUSIVE (coarse grained) GRANITIC rock?
500
The classification of sedimentary rock that is not made from pieces of pre-existing rocks.
What is a CHEMICAL sedimentary rock?
500
The type of metamorphism that occurs due to pressure from mountain formation.
What is REGIONAL METAMORPHISM?
500
The rock type that is MOST LIKELY to contain fossils. (hint: think of the national parks projects)
What are SEDIMENTARY ROCKS?
