|
|
What is an example of earth changing |

|
|
|
An earthquake is caused by |
Sudden movement of Rocks in earths crust large section of rocks in earth crust PUSH OR PULL |
|
|
|
Energy |
Energy is release as seismic waves |
|
|
|
The focus |
Under the crust were the rock first breaks is called the focus |
|
|
|
Fault |
The focus sends out a seismic waves which cause the crust to crack creating a fault |
|
|
|
Where is the epicentre |
Directly above the focus is called The epicentre |
