(離題?)

查實我都唔多記得geog d野..見到記得先答下==
不過題目都唔算係太需要geog既知識..只係convection..

又有野問啦我

可唔可以講下點解mid-oceanic ridges有transform faults?
mid-oceanic ridge is caused by tensional force
lateral force causes the mid-oceanic ridge to break and be displaced
我唔明白why 又可以tensional force又lateral force...

仲有呢,我都仲係唔明convection current個到
convection current點解又會有divergent, convergent current ge?

第一個問題唔記得晒

第二個問題lateral force=橫向的力(tensional force都係lateral force)

第三條問題即係有好多個convectional cells 放埋晒一齊
               假設一個convectional cell去到上面果陣 兩條current係diverge既
　　　　　咁係正同一個convectional cell上面既兩塊板就會被拉開
               係正兩個convectional cell上面既兩塊板就會撞埋一齊..
                (其實我想畫圖比你睇..不個電腦個小畫家比人del左..)
