Plates and Earthquake/Volcano distribution

Question 1

How do Constructive Plates cause Earthquakes?

Answer 1

1. As the plates move apart, a gap appears between the two plates.
2. This gap allows magma to rise up from the mantle.
3. This movement of magma creates small earthquakes.

Question 2

How do Destructive Plates cause Earthquake?

Answer 2

1. The Oceanic and continental plate collide
2. The Oceanic plate subducts (goes under the other plate) because it has more mass.
3. As the plate subducts it sticks with the continental plates, increasing the pressure between them.
4. When the pressure reaches a critical
   level, it is released in the form of seismic waves forming a violent earthquake.

Question 3

How do Conservative Plates cause Earthquakes?

Answer 3

1. As the plates move side by side they grip together and stop each other from moving
2. This increases the pressure between them.
3. When the pressure reaches a critical
   level, it is released in the form of seismic waves forming a violent earthquake.

Question 4

How are Volcanoes formed on Constructive Plate Boundaries?

Answer 4

1. As the plates move apart, a gap appears between the two plates.
2. This gap allows magma to rise up from the mantle, creating new land and volcanoes.
3. Over time, this allows the sea floor to spread.

Question 5

How are Volcanoes formed on Destructive Plate Boundaries?

Answer 5

1. The Oceanic and Continental plate collide.
2. The Oceanic plate subducts because it has more mass.
3. As the plate subducts, friction heats up the
   Oceanic plate, forming magma.
4. The magma rises to the surface as it is less dense than the surrounding rock.
5. This then forms a volcano.

Question 6

How are Volcanoes formed on Conservative Plate Boundaries?

Answer 6

Trick Question ; Volcanoes are not formed at conservative plate boundaries.
