What are Divergent Boundaries? |
Divergent Boundaries is the motion when plates move apart from one another |

|
What are Convergent Boundaries? |
When the crust is destroyed as one plate dives under another. |

Minerals found in rocks react with water Chemicals can be dissolved into water Common example: Sodium Chloride |
|
|
Earthquakes |
