唔知點讀plate個課, 好唔熟
有無咩方法?

kiyiptsang

Physical 方面
1. 背Plate 名 (年年MC / SQ第一個分題出.. 但其實唔會出好難果d..多數玩Nazca / Philippine)
2. Process (Tsunami , Earthquake & Volcanic Eruption)
3. 記低所有碰撞的Landform (最好搞mindmap)
4. Annotated Diagram
Cultural 方面
1. LDC 同MDC 係應對Hazard 時既唔同因素 (數隻Keywords)
2. Measure (記共同的方法)
3. Leave / Stay 既原因 (三種Hazard 都有共同Point的)

earthquake  volcanic  d  process  有無方法易記d?

kiyiptsang

頭三個步, process 都係一樣 (line of weaknesses , release of pressure 仲有一個唔記得左 )

goobeee

there are common  steps for earthquakes, tsunami and vol eruption
1. magma current (converging/ diverging/ lateral movement)
2. plate movement (XX and YY plates move toawrd/ apart/ slide pass each other) along destructive/ constructive/ conservative plate boundary
3. force (compressional/ tensional/ shear)
4. any subduction ? (only destructive plate boundary, OC vs CC/ OC vs OC will hv)
above= common steps

hence
earthquake
5. stress increases, when stress exceed strength of rock, faulting occur (reverse/ normal/ tear)
6. earthquake occur and energy release in form of seismic wave
tsunami need to continue
7. the energy released from epicentrer stip up wave at middle of sea
8. the wave travel towards coast, sea bed become shallower, friction increases
9. wave height increase and wave length reduce, tsunmia occur

volcanic eruption = from step 1-4 +
5. pressure increases, line of weakness widened into cracks to release pressure
6. magma rise up through crack onto earth surface
7. lava cool and solidifies, volcanic eruption takes place
