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.

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.

look for oil, gas, and other
resources.

The layer below the rigid
lithosphere is a zone of asphaltlike consistency called the
Asthenosphere.
The
asthenosphere
is the
semi-rigid part

flows.

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.
