Igneous Rock
This is molten rock found below the earth's surface.
What is magma?
tiny pieces of rock, sand, shells, etc. is 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.
Weathering and Erosion
True or False Obsidian (glassy, no crystals) is an extrusive rock.
True - fast cooling on the surface, no crystals formed.
Examples of Sediments
Broken down pieces of rock,
Sand
Soil
True of False- Metamorphic rocks can change in size and shape.
True- due to intense heat and pressure
Undergoing weathering and erosion, will show which type of rock?
Sedimentary
Difference between magma and lava.
Magma when is underground, lava after errupts.
Igneous rocks are categorized as _________ or _________, depending on where the molten rock cooled.
What are extrusive and intrusive.
A sedimentary rock can change during the process. True or False.
True- the rock cycle is continuous
Minerals can be added or substracted due to transformation. True or False
True
The rock cycle is continuous. True or false.
True.
Give an example of a rock
Various (sandstone, marble, conglomerate, coal)
Intrusive rocks can be found
A. On the Earth's surface
B. Underneath the earth's surface
B. 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 or organic sedimentary rock?
Difference between time it takes to form igneous and sedimentary rocks.
Igneous rocks take from days to thousands of years to form, sedimentary rocks take millions of years.
_________ and ____________ turn sedimentary rocks into metamorphic rocks.
Heat and pressure
Give three properties you would use to describe a rock.
Answers may vary (colour, hardness, size of crystals, layered/non-layered, banded/not-banded, air bubbles, glassy, shiny/dull)
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.
Weathering (breaking down of rocks in sediments) can be_____, _______and_____ . Give two types of weathering.
Mechanical (due to atmospheric processes such as rain, wind, freeze/thaw).
Chemical, due to chemical reactions between rocks and acid rain, water or different types of rocks.
Biological (plants, animals).
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__________
