What are the three classes of rocks? Answer: Sedimentary, Igneous, and Metamorphic
Why do some places made of rock have different heights?
Due to the rock formation processes...
Ocho Stinko!
How is magma formed?
From melting rock
Can an igneous rock become another igneous rock? If so, how?
Yes, by melting again and then solidification

How do sediments become sedimentary rock?
Deposition, burial, compaction, and cementation
What is one way a sedimentary rock can indirectly become an igneous rock?
By becoming a metamorphic rock first
What is compaction?
The process of pressing sediments together under their own weight.
Which type of rock is typically formed from layers of sediment compressed together?
Sedimentary Rock
How are sediments formed?
Uplift, weathering, and erosion
What is the first step in the formation of sedimentary rocks?
A. Deposition
B. Inflammation
C. Molten Rock
A. Deposition
Which process cannot happen?
a. Igneous rock-> heat and or pressure-> metamorphic rock

What happens during cementation?
Dissolved minerals crystallize and glue particles of sediment together.

Triple Whipple!
What process turns igneous rock into metamorphic rock?
Heat and/or pressure
Which process is essential for the formation of metamorphic rocks but not for sedimentary rocks?
Pressure
What is the sequence of processes that change magma into sedimentary rock?
Solidification to igneous rock, then weathering and erosion, followed by deposition, burial, compaction, and cementation

How does igneous rock become sedimentary rock?
Weathering and erosion, followed by deposition, burial, compaction, and cementation
Describe how metamorphic rocks can become igneous rocks.
By melting to magma, then solidification
Describe a path in the rock cycle that involves all three rock types.
Sedimentary rock can transform into metamorphic rock through heat and pressure, then melt into magma and solidify into igneous rock.
What is the difference between magma and lava?
Magma is molten rock beneath the Earth's surface; lava is molten rock that has erupted onto the Earth's surface.
