3. Subduction Zone
Cause & Effect: When oceanic plate goes
under continental crust because it has more
dense. It forms volcanoes and trench.

4. Cause & Effect: Two Plates move toward each
other and forms mountain or trench.
Convergent Boundary
Himalaya Mountain

5. Divergent Boundary
Cause & Effect: Two plates move away from
each other, forms Mid-ocean ridge or valley.
Jiuzhaigou Valley

6. Transform Boundary
Cause & Effect: Two plates slide pass each
other and creat earthquake and tsunami.
San Andreas fault

7. Earthquake
Earthquake also called seismic wave, is
caused by the movement of the crusts in
transform boundary.
China Sichuan earthquake in 2008

8. Seismic Wave
● P wave ( Primary wave, comes first and move up and
down).
● S wave ( Secondary wave, comes after P wave, moves
from left to right).
● L wave ( Love wave is the most dangerous wave,
moves all over).

9. Seismic Wave
● Epicenter: the original point where earthquake begins
above the ground.
● Focus: the point where
earthquake starts under
ground.

10. Tsunami
Tsunami is caused by the movement of the lands under the
ocean and lead to huge ocean wave and horrible
destruction.
Tsunami in Japan in 2014

11. Fault Zone
Normal Fault: Moves down.
Reverse Fault: Moves up.
Strike-slip Fault: Moves pass away.

12. Hot Spot
Conviction current circulates hot and cold
materials in the mantle and creates hot spot
where has extreme hot temperature and active
volcanoes.

13. Volcano
Cinder Cone: It has bowl shape crater and
shorter than other volcanoes, which made from
lava push out in the center of the volcano, cool
and breaks, fall as cinders
around the vent.

14. Volcano
Composite Volcano: steep sided, it has vents
where magma comes out beside the crater.
Fuji Volcano in Japan

15. Shield Volcano
Shield volcano is wide volcano built of fluid lava
flows.
Mauna Loa Shield Volcano

16. Volcano
Volcano is a mountain has a crater or vent
where magma comes through. It erupt because
of density and pressure. When surrounding
rock has more dense than magma causes
magma to rise.

17. Earth Interior
Crust: solid, land.
Mantle: magma, liquid.
Outer cone: solid
Inner core: liquid, hottest.
