Describe Which Way Do Destructive Plate Margins Move?
- At Destructive Plate Boundaries They Move Towards Each Other.
Describe what Happens In a Destructive Plate Margin?
- The Heavier Oceanic Plate Sinks Under The Contention Plate At Around a 45 Angle. Because Its Heavier and Denser.
Write a Definition Of a Ocean Trench?
- Its The Land Between The Oceanic and Continental Plate
The Ocean Trench Near Japan Is (_________) Deep.
11 Km
Describe Which Way Do Constructive Plate Margins Move?
- At Constructive Plate Margins They Move Away From Each Other.
Describe what Happens In a Constructive Plate Margin?
- When the 2 Plates Are Pulled Apart Magma Then Rises and Fills in Between The Gap This Is Cause By The Convection Currents In The Magma.
Describe Which Way Do Conservative Plate Margins Move?
- They Move Slide To Slide Each Other.
Describe what Happens In a Conservative Plate Margin?
- The Plates Move In Different Directions and Speed Then When They Move Side By Side Friction Builds up Then This Released Lost Of Vibrations Which Creates A Earthquake.
Name 4 Ways That Volcanoes Can Be Reduced?

Name 5 Things That Could Predict That There Is A Volcano and explain Them?
- Ground Deformation
- Gases
- Changes In Heat
- Vibrations Underground
- Smaller Eruption Of Stream and Smoke
Explain How Scientise Will Know a Volcanoes Will Happen Due To The Gases Released?
- Certain Gases Indicate Rising Magma Such as Sulfurous Gases
