False
True or false:molten rock is only found close to the surface.
False
A ______ is a common structure found in metamorphic rock.
Fold
__________ metamorphic rock contains minerals that are arranged in plates or bands.
Foliated
Which process changes igneous rock into metamorphic rock?
Heat and pressure
Metamorphism involves the addition of ____ and _______ to pre- existing rocks.
Heat, pressure
Describe two ways a rock can undergo metamorphism.
If the temperature or pressure of the new environment is different and if the rock is being heated by nearby magma.
Soldification of molten materials forms________ rocks.
Igneous
As magma cools, it forms ________ rock by the process of ________
Igneous and cooling
Solid magma forms_____
Igneous rocks
Explain why some minerals only occur in metamorphic rocks.
Large movements within the crust of the earth cause additional pressure to be exerted on a rock.
Molten rock inside the earth is called _____.
Magma
Igneous rock forms when __________________.
Magma cools and solidifies.
In order to form magma, what must happen to sedimentary, metamorphic or igneous rocks?
Melting
Which process changes sedimentary rock into igneous rock?
Melting
Heat and pressure acting on igneous rocks form __________.
Metamorphic
Subjecting sedimentary rocks to extreme heat and pressure forms _________ rocks.
Metamorphic
The three main groups of rocks are sedimentary,_________, and igneous rocks.
Metamorphic
_______ rock solidifies to form igneous rocks.
Molten
Can sedimentary rock form directly from metamorphic rock? Explain your answer.
No, it must turn to sediment first.
Sedimentary rock is classified into all of the following ,main categories except... A) clastic B) chemical C)nonfoliated D) organic
Nonfoliated
Heat and ____ are key factors in the formation of metamorphic rocks.
Pressure
Definition: the process where rocks form, changes,gets destroyed, then forms again.
Rock cycle
______ are made of one or more minerals.
Rocks
Igneous rocks can form_________. ___________, and ____________ rocks.
Sediment, magma, and metamorphic
Sedimentary rocks can form ________, _______, and __________ rocks.
Sediment, magma, and metamorphic
Compaction and cementation of sediments forms __________ rocks.
Sedimentary
Deposition and burial of sediment forms ________ rocks.
Sedimentary
The particles resulting from weathering of rocks may lead to the formation of __________ rock.
Sedimentary
Describe how each type of rock changes as it moves through the rock cycle.
Sedimentary = Heat and pressure metamorphic= melting igneous = weathering and erosion.

True
True or false: The process of rain wearing down rocks is an example of weathering.
True
True or false: erosion is responsible for transporting sediment.
True
True or false: magma is the result of rocks being heated into liquid rock.
True
