Question and Answer Samples and Techniques
TRUE or FALSE?TRUE or FALSE?The Three major types of rocks are Igneous, Sedimentary and Extrusive.
Metamorphic
Cementation often occurs directly after Earth materials are _____________ ?
CompactedThis process forms what type of rock?
Which of the following would NOT be a major process in the formation of sedimentary rock.
erosiondeposition
meltingcompaction
Ripple marks likely indicate that the rock formed……..
Near or in water
TRUE or FALSE?TRUE or FALSE?Metamorphic rocks that have a banded appearance due to the alignment of minerals are called foliated rocks.
Which rock is made up of the smallest sediments?
ShaleBreccia
SandstoneConglomerate
A fine grained igneous rock forms…..
Deep within the EarthFrom magma
As the result of slow coolingAs the result of quick cooling
The formation of igneous rock is powered by?
Earth’s Internal Heat
If a rock has a porhyrtic texture, what can we conclude about the rock?
The rock went through at least two different cooling periods.
Minerals that crystallize from magma do not form at the same rate or same time. These rocks usually
have larger crystals surrounded by much smaller crystals.
How could you easily distinguish a black and white gneiss from a similar colored granite?
The gneiss is foliatedFoliated = bands or layers
Marble is an example of a
foliated metamorphic rocknonfoliated sedimentary
rocknonfoliated metamorphic rockintrusive igneous rock
Which of the following is a fine-grained, light-colored extrusive igneous rock?
RhyoliteGranite
LimestoneSchist
Igneous rocks are classified by
composition and age. composition and texture. texture and size. texture and presence of fossils.
What are the main agents of metamorphism?
compaction, cementation, and heat heat, pressure, and hydrothermal
solutions heat, pressure, and erosion heat, weathering, and erosion
Which of the following is NOT an example of an igneous rock?
granite
sandstone
basalt rhyolite
A(n) __________is any solid mass of mineral or mineral-like matter that occurs naturally as part of Earth.
Rock
Most rocks, such as granite, occur as a solid mixture of _____________?
Minerals
This produces low-grade metamorphism?
Contact metamorphism
This occurs during mountain building?
Regional Metamorphism
TRUE or FALSE?TRUE or FALSE?Much of the upper mantle is thought to be made of granite.
