Test (53 cards)
What are the three major types of rocks?
Sedimentary, igneous, and metamorphic
How are igneous rocks formed?
From the melting and cooling of magma or lava
What process leads to the formation of sedimentary rocks?
Erosion, deposition, compaction, and cementation
What is the term for molten rock beneath Earth’s surface?
Magma
What is it called when magma reaches the surface?
Lava
What is crystallization in relation to igneous rocks?
The solidification of lava or magma

What is the process by which rocks change into new rocks called?
The rock cycle
What type of rock is formed under tremendous heat and pressure?
Metamorphic rock
True or False: All sedimentary rocks form from the pressure of compacting sediments.
False
What is the term for the physical change in metamorphic rocks that forms bands of different-colored crystals?
Foliation
What type of igneous rock cools slowly beneath Earth’s surface?
Intrusive igneous rocks
What type of igneous rock cools quickly on Earth’s surface?
Extrusive igneous rocks
List the processes involved in the formation of sedimentary rocks.
- Weathering
- Erosion
- Deposition
- Compaction and cementation
What is an example of a chemical sedimentary rock?
Gypsum
What happens to mud during metamorphism?
It changes into slate
What type of rock is gneiss?
Foliated metamorphic rock
What systems interact to recycle rock materials on Earth?
- Geosphere
- Atmosphere
- Hydrosphere
- Biosphere
Where does the energy needed for geological processes come from?
- The Sun
- Earth’s hot interior
Fill in the blank: __________ rocks are formed from sediments collected at the bottom of bodies of water.
Sedimentary
What type of rock is formed from the cooling and solidification of magma or lava?
Igneous
Igneous rocks can be classified into two main types: intrusive (formed from magma) and extrusive (formed from lava).
What type of rock is formed through the accumulation and compaction of sediments?
Sedimentary
Sedimentary rocks often contain fossils and are formed in layers.
What type of rock is formed under intense heat and pressure?
Metamorphic
Metamorphic rocks can originate from either igneous or sedimentary rocks.
