Senior High School Lesson

1. DEFORMATION OF THE EARTH’S CRUST

2. IF YOU DIG DOWN ALL THE
WAY INTO THE CENTER OF
THE EARTH, WHAT WOULD
YOU SEE?

3. IN A ONE WHOLE SHEET OF PAPER, SKETCH
YOUR IDEAS OF WHAT THE INTERIOR OF THE
EARTH LOOKS LIKE WITHIN 10 MINUTES.
• INCLUDE AND LABEL THE FOLLOWING:
• CHARACTERISTICS OF THE MATERIALS (TEMPERATURE, COMPOSITION, AND
PHYSICAL STATE)
• BOUNDARIES BETWEEN REGIONS WITH DIFFERENT TYPES OF MATERIALS
• CHANGES THAT TAKE PLACE AS YOU GO DEEPER INTO THE CENTER OF THE
EARTH (CHANGE IN TEMPERATURE, PRESSURE, AND DENSITY)

4. PRESENT YOUR DIAGRAMS AND
DESCRIPTIONS IN FRONT OF THE CLASS.

5. DEFORMATION OF THE EARTH’S CRUST: THE
INTERNAL STRUCTURE OF THE EARTH

7. Inner core
Outer core
Mantle
Crust

8. CRUST
•THIN, OUTERMOST LAYER OF THE
EARTH MADE UP OF TWO DIFFERENT
TYPES, NAMELY CONTINENTAL
CRUST AND OCEANIC CRUST

9. MANTLE
•MIDDLE LAYER OF THE EARTH
BETWEEN THE CRUST AND THE
CORE WHICH MAKES UP ABOUT
83% OF EARTH’S INTERIOR

10. CORE
• INNERMOST LAYER OF THE
EARTH; OUTER CORE IS IN A
LIQUID STATE, WHEREAS INNER
CORE IS IN A SOLID STATE

11. LITHOSPHERE
• RIGID OUTER LAYER OF THE
EARTH WHICH IS MADE UP OF
THE BRITTLE CRUST AND THE
UPPER MANTLE

12. MESOSPHERE
• LAYER OF WEAK, DUCTILE
ROCK IN THE MANTLE
SITUATED BELOW THE
LITHOSPHERE

13. MOHO
•BOUNDARY
SEPARATING THE CRUST
AND THE MANTLE

15. SEISMIC WAVES
• AN ELASTIC SHOCK WAVE THAT
TRAVELS OUTWARD IN ALL
DIRECTIONS FROM AN
EARTHQUAKE SOURCE

17. CONVECTION
• TRANSFER OF HEAT BY
MASS MOVEMENT OR
CIRCULATION OF A
SUBSTANCE

19. PLATE TECTONICS
• THEORY WHICH PROPOSES THAT THE
CRUST AND UPPER MANTLE OF THE
EARTH ARE COMPOSED OF SEVERAL
LARGE, THIN, AND RELATIVELY RIGID
PLATES THAT MOVE RELATIVE TO ONE
ANOTHER

21. PLEASE BRING THE FOLLOWING TOMORROW
• PENCIL, CRAYONS, COMPASS AND
DRAWING PAPER
