1
Slate is a metamorphic rock that forms from shale, which is a sedimentary rock. What is needed to form slate from shale?
Heat and pressure
Weathering and erosion
Melting and solidification
Compaction and cementation
2
What process formed our
igneous
rock in the starburst lab?
Metamorphic rock was melted on hotplate & allowed to cool down
Sedimentary rock was warmed in our hands and flattened with a book
Sedimentary rock was cut into pieces to form sediment
3
Which of the following is one of the three main types of rock?
Metamorphic
Obsidian
Sand
Basalt
4
As the young Earth cooled, the heaviest material
sank to the center.
rose to the top.
flew out into space.
formed the mantle.
5
Which is true?
the deeper the layer, the cooler the temperature.
each layer is about the same temperature.
all layers are the same depth.
the deeper the layer, the hotter the temperature.
6
One can best show Earth's layers by a
peach half, showing the skin, flesh, and pit.
round rock.
a slice of frosted cake.
a soccer ball.
7
Oceanic crust is
on land
flat and sandy
more dense than continental crust
less dense than continental crust
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
Where does lava cool quickly?
Above ground
Lava always cools quickly
Below ground
Lava never cools quickly
10
Continental crust is
deep in the ocean.
the part of the Earth's crust that forms land masses.
made of molten iron.
11
Which layer do the tectonic plates move on top of?
Core
Mesosphere
Crust
Asthenosphere
12
Erosion is a process that slowly changes rocks. Which of the following MOST LIKELY causes pebbles in a stream to erode?
Movement of ice
Flowing water
Freezing and thawing
Force of gravity
13
Earth's crust is
soft and thin.
soft and thick.
hard and thick.
hard and thin.
14
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.
15
What evidence can you find on a rock that it is a sedimentary rock?
Smooth and glassy
Visible layers
Folds and bends
Large crystals
16
Which layer of Earth is divided into tectonic plates?
Mantle
Asthenosphere
Mesosphere
Lithosphere
17

False
True
18
The Earth has how many compositional layers?
0
5
4
3
19
Convection takes place in the ____________ and can described as __________________
Mantle/rising of hot magma and sinking of cool magma
Core/rising of cool magma and sinking of hot magma
Crust/rising of cool magma and sinking of hot magma
20
The Earth has FIVE physical layers. What is the correct order from outside to inside?
Lithosphere, Mesosphere, Asthenosphere, Outer Core, Inner Core
Crust, Mantle, Lithosphere, Outer Core, Inner Core
Lithosphere, Asthenosphere, Mesosphere, Outer Core, Inner Core
Lithosphere, Mantle, Crust, Inner Core, Outer Core
21
Which of the following is the THICKEST layer?
the mantle.
the crust.
the outer core.
the inner core.
22
The mantle is made of
solid rock
dirt.
very hot rock that flows like hot asphalt
liquid metals
23
How was our
sedimentary
rock formed in our starburst lab?
Sedimentary rock was cut into pieces to form sediment
Metamorphic rock was melted on hotplate & allowed to cool down
Sediment was gently pushed together representing compaction & cementation
24
What must happen for metamorphic rock to be transformed into igneous rock?
Metamorphic rock cannot be transformed into an igneous rock
Metamorphic rock needs to experience great heat and pressure
Metamorphic rock must melt and the magma has to cool
Metamorphic rock needs to be broken down by weathering & erosion
25
It is most likely that the high pressure in the core comes from
the mass and weight of the layers above the core.
gasses deep inside the Earth.
high temperatures.
low temperatures.
