1. Which is not a layer of the
Earth?
A.Crust

what is the order of the Earth’s
layers?
A. Core - Mantle – Crust – Inner Crust
B. Crust - Mantle - Outer Core - Inner Core

3. The core of the Earth is made
up almost completely of which
element?
A. Iron
B. Granite
C. Sulfur
D. Calcium

4. Which layer of the earth is the
thickest?
A. Core
B. Crust
C. Mantle
D. All of them have the same
thickness

5. Which layer of the Earth is
liquid?
A. Crust
B. Outer Core
C. Inner Core
D. Mantle
earthscience: LAYERS OF THE EARTH
TRUE OR FALSE?
F 6. The center of the Earth is
made of molten rock.
T 7. Most of the Earth’s heat is
stored in the mantle.
T 8. The outer core is liquid.
earthscience: LAYERS OF THE EARTH
TRUE OR FALSE?
T 9. Earthquakes occur when
heat travels through the
mantle and causes tectonic
plates to shift.
F10.The thinnest parts of the
Earth’s crust are its
continents.
earthscience: LAYERS OF THE EARTH
TRUE OR FALSE?
T 11. Extreme pressure causes the
inner core of the Earth to
remain solid.
T 12. The crust of the Earth is much
cooler than its other layers.
T 13. The Earth’s mantle is flexible
and shifts under heavy loads.
earthscience: LAYERS OF THE EARTH
TRUE OR FALSE?
F14. The core is where geologists
look for oil, gas, and other
resources.
F15. The crust is separated into
two parts: upper and lower
crust.

the Earth look like?

The crust and
the upper layer
of the mantle
together make
up a zone of
rigid, brittle
rock called the
Lithosphere..
The layer below the rigid
lithosphere is a zone of asphaltlike consistency called …
The layer below the rigid
lithosphere is a zone of asphaltlike consistency called the
Asthenosphere.
The
asthenosphere
is the
semi-rigid part
of the middle
mantle that
flows.
The
boundary
between the
crust and
the mantle
is called
the...
Mohorovicic
Discontinuity
Lower mantle
Asthenosphere
The boundary
between the crust
and the mantle is
called the
Mohorovicic
(Moho)
discontinuity.
Is the
temperature
all over the
mantle
the same
or constant?
When the
convection
currents
flow in the
asthenosphere
they also move
the crust.
