1
What must happen for metamorphic rock to be transformed into igneous rock?
Metamorphic rock needs to be broken down by weathering & erosion
Metamorphic rock must melt and the magma has to cool
Metamorphic rock needs to experience great heat and pressure
Metamorphic rock cannot be transformed into an igneous rock
2
Convection takes place in the ____________ and can described as __________________
Core/rising of cool magma and sinking of hot magma
Crust/rising of cool magma and sinking of hot magma
Mantle/rising of hot magma and sinking of cool magma
3

a slice of frosted cake.
4
Which layer of Earth is divided into tectonic plates?
Lithosphere
Mantle
Asthenosphere

5
Slate is a metamorphic rock that forms from shale, which is a sedimentary rock. What is needed to form slate from shale?
Compaction and cementation
Melting and solidification
Heat and pressure
Weathering and erosion
6
The mantle is made of
liquid metals
solid rock
dirt.
very hot rock that flows like hot asphalt
7
Erosion is a process that slowly changes rocks. Which of the following MOST LIKELY causes pebbles in a stream to erode?
Force of gravity
Freezing and thawing
Flowing water
Movement of ice
8
How was our
metamorphic
rock formed in our starburst lab?
Sedimentary rock was warmed & flattened representing heat & pressure
Sediment was gently pushed together representing compaction & cementation
Metamorphic rock was melted on hotplate & allowed to cool down
9
Which of the following is one of the three main types of rock?
Sand
Metamorphic
Obsidian
Basalt
10
Which of the following is the THICKEST layer?
the crust.
the mantle.
the inner core.
the outer core.
11
How was our
sedimentary
rock formed in our starburst lab?
Sediment was gently pushed together representing compaction & cementation
Metamorphic rock was melted on hotplate & allowed to cool down
Sedimentary rock was cut into pieces to form sediment
12

False
True
13
Earth's crust is
hard and thin.
hard and thick.
soft and thick.
soft and thin.
14
As the young Earth cooled, the heaviest material
rose to the top.
flew out into space.
sank to the center.
formed the mantle.
15
It is most likely that the high pressure in the core comes from
low temperatures.
gasses deep inside the Earth.
high temperatures.
the mass and weight of the layers above the core.
16
Continental crust is
the part of the Earth's crust that forms land masses.
deep in the ocean.
made of molten iron.
17
What process formed our
igneous
rock in the starburst lab?
Sedimentary rock was warmed in our hands and flattened with a book
Sedimentary rock was cut into pieces to form sediment

Below ground
Lava always cools quickly
23
From what you have learned, you can conclude that
Earth is made entirely of pure iron.
the inner core is mostly gas.
iron will melt only at a very high temperature.
all layers of Earth are divided into plates.
