A. CrustB. MantleC. Outer CoreD. Inner Crust
2. Starting with the outermost layer, what is the order of the Earth’s layers?
A. Core - Mantle – Crust – Inner CrustB. Crust - Mantle - Outer Core - Inner
CoreC. Outer Mantle - Inner Crust – Inner CoreD. Outer Crust - Inner Core – Outer Mantle
3. The core of the Earth is made up almost completely of which element?
A. IronB. GraniteC. SulfurD. Calcium
4. Which layer of the earth is the thickest?
A. CoreB. CrustC. MantleD. All of them have the same
thickness
5. Which layer of the Earth is liquid?
A. CrustB. Outer CoreC. Inner CoreD. Lithosphere
TRUE OR FALSE?

9.Earthquakes occur when heat travels through the mantle and causes tectonic plates to shift. 10.The thinnest parts of the Earth’s crust are its continents.

TRUE OR FALSE?
11.Extreme pressure causes the inner core of the Earth to remain solid. 12.The crust of the Earth is much cooler than its other layers. 13.The Earth’s mantle is flexible and shifts under heavy loads.

14.The core is where geologists look for oil, gas, and other resources. 15.The crust is separated into two parts: upper and lower crust.

The crust and the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere..
The asthenosphere is the semi-rigid part of the middle mantle that flows.
Lower mantle
MohorovicicDiscontinuity
Astheno-sphere
When the convection
currents flow in the
asthenosphere they also move
the crust.
The boundary between the outer core and the mantle is called ….
What is the inner
core made of?
What is the inner
core made of?
Why is the inner core
solid despite its extremely
high temperature?
