Continental plates are made of a rocky substance. They move across the mantel of the earth, the mantel is a liquidy rock layer under the earth crust. The Plates are what cause earthquakes. On faults the plates grind together untill pressure becomes unbearable for the plates and they suddenly move or they push up and make mountains. Also they can push down and make valleys.
Plates affect us by the earthquakes they cause. A magnitude 7-9 earthquake, (7 will destroy well built buildings. 9 wide spread destruction) will destroy practically everything.
I really enjoy learning from your writing!!

Great write up on the cause and effects of earthquakes. It is good to take an interest in things that are a part of day to day life. I like the descriptions that accompany your drawings, they are really useful. Looking forward to seeing what you write about next. keep up the good work.
