Igneous Rock
volcano
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.
What is erosion
When sediments move from place to place
This is molten rock found below the earth's surface.
What is magma?
Examples of Sediments
Broken down pieces of rock,
Sand
Soil
True or False: Metamorphic rocks are formed when sediments break apart. If false, please correct the statement.
False- due to intense heat and pressure
After rocks undergoing weathering and erosion, what could be the next stage in the rock cycle?
Sedimentary rock
Give an example of a rock
Various (sandstone, marble, conglomerate, coal)
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.
Where do sediments come from?
Larger rocks
they are both formed under pressure
The rock cycle is continuous. True or false.
True.
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
Name a physical quality of igneous rock
glassy
many small holes
crystals
Name a physical quality of sedimentary rock

layers
fossils
What did we do in the starburst lab to simulate the formation of metamorphic rocks?
Held the starburst in our hands to warm it and put a lot of pressure on it (we even smashed it under a book)
_________ and ____________ turn sedimentary rocks into metamorphic rocks.
Heat and pressure
What process breaks down rocks to create sediments?
weathering
Name an igneus rock that we looked at in class and is black in color
obsidian
There are different types ofweathering that can be classified into 3 different groups. What are they?
Mechanical /physical (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).
Name a physical quality of metamorphic rock
banded crystals (wavy lines)
True or false: Any type of rock can become any other type of rock.
True
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)
