What are the boundaries and what do they do?

Definition

convergant- plates move together

divergant- plates move away from eachother

What is the elastic reboud theory?

 

Definition
stress builds up along the fault lines, the rock eventually snaps and send outs waves to form an earthquake. The ground shakes due to S waves.

How is lightning and thunder formed?

Definition

Lightning-- It is a natural discharge of the static electricity built up in storm clouds. static electrical discharges such as lightning are caused by separation of charges into positive and negative ions.

 

Thunder-- cause by rapid expansions of the air surrounding the path of a lightning bolt, when it breaks it makes the rubmbling sound called thunder.
