Igneous Rock
What is molten rock found below the earth's surface called?
What is magma?
Tiny pieces of rock, sand, shells, etc. are called what?
What is sediment?
Metamorphic rocks are formed due to _______ and _______.
Heat and Pressure
When sediments undergo compacting and cementation processes, they become which type of rock.
Sedimentary rocks.
Two major contributing factors to sediment
Weathering and Erosion
Igneous rocks are categorized as _________ or _________, depending on where the molten rock cooled.
What are extrusive and intrusive.
A sedimentary rock can change into an igneous rock or a metamorphic rock over time. True or False.
True
Why are metamorphic rocks harder/stronger than other rocks?
The extreme pressure and heat fuses them together
The rock cycle is continuous. True or false.
True.
Give an example of a rock
Various (sandstone, marble, conglomerate, coal)
True or False Obsidian (glassy, no crystals) is an extrusive rock.
True - fast cooling on the surface, no crystals formed.
What are two examples of sediments?
Broken down pieces of rock
Sand
True of False- Metamorphic rocks can change in size and shape.
True- due to intense heat and pressure
If a metamorphic rock undergoes weathering, what will it become?
Sediment
What is the difference between magma and lava?
Magma when it is underground, lava is after it errupts.
True or False: Igneous rocks are formed when sediments break apart. If false, please correct the statement.
False - igneous rocks form from the cooling and solidification of magma/lava.
The breaking down of rocks into sediments is caused by ___________ or ______________.
What is Weathering and erosion?
Which experiment describes the formation of a Metamorphic Rock?
A. Using the blow drier, and applying pressure
B. Melting the chocolate and allowing it to cool
C. Breaking the pieces into smaller particles
A. Using the blow drier, and applying pressure
True or false: Any type of rock can become any other type of rock.
True
Igneous rocks are formed from cooled__________
Extrusive rocks can be found where?
Underneath the earth's surface
This type of sedimentary rocks form when dead plants from millions of years ago mineralizes. We use it to heat homes or fire up the grill!
What is coal?
Which rock takes the least amount time to form? Igneous or Sedimentary?
Igneous rocks- take days to thousands of years to form, while sedimentary rocks take millions of years.
___________ and ___________ turn sedimentary rocks into igneous rocks.
Melting and cooling
Give two pieces of evidence you would use to identify a rock.
Answers may vary (size of crystals, layered/non-layered, air bubbles, glassy, shiny/dull, fossils, etc)
