Rocks
True or False: There is no way that metamorphic rock can become sedimentary rock.
False : Weathering followed by lithification would turn metamorphic rock into sedimentary rock.
A rock that forms from magma is a _______ __________rock.
intrusive igneous
A mixture where the substances are thoroughly mixed up
homogeneous
A nearly universal solvent
WATER
A substance that cannot be broken down chemically
Element
True or False: Sandstone is made from larger particles of sediment than siltstone.
True: Sandstone has larger particles
Which type of rock requires both heat and pressure to form?
regional metamorphic
The process of heating a mixture to kill the bacteria in it
pasteurization
The ability of fat molecules to keep air molecules suspended
STRUCTURAL INTEGRITY
A liquid with air bubbles trapped in it
Foam
Which of the following MUST be in between two strata of rock?
A bedding plane
An unconformity
A disconformity
A paraconformity
Bedding plane
True or False: Sedimentary rock is more likely to contain fossils than igneous rock.
True
The process of breaking up fat into tiny pieces that can remain suspended
homogenization
A substance made when two or more elements combine chemically
COMPOUND
A combination of two or more pure substances where each keeps its own properties-a new substance is NOT formed.
MIXTURE
What is the simplest way for an igneous rock to become a sedimentary rock? Tell me each thing that must happen
Weathering, then lithification
True or False: Lithification is always a slow process
False
A mixture where the substances are NOT evenly mixed up
heterogeneous
What elements are found in the compound CH5 and how many of each?
1- Carbon
5-Hydrogens
Give an example showing that a compound does not act like the elements it is made from.
Liquid water does not behave the same as
Oxygen or Hydrogen gas
Which of the following four types of coal produces the most pollution when it is burned?
anthracite, bitunimous, sub bituminous, or lignite
lignite-lowest grade and more contaminents
A dike can be made of either igneous rock or sedimentary rock. Explain how both are formed
An igneous dike is formed from magma that is pushed up through cracks in the rocks. The sedimentary dike is formed from sediments pushed down in a crack.
What elements and how many of each are found in the compound H2O? And what compound is this?
2 -Hydrogen
1-Oxygen
Water
Explain why water is by many to be considered the universal solvent
Most substances will dissolve in water because of its unique shape
Explain why whipped cream eventually melts into a pool of white liquid.
The fat molecules become unable to hold the gas and it escapes.
