Question 15

Examples of Constructive Plate Margin

Answer 15

Mid Atlantic ridge( A chain of undersea volcanoes)

Question 16

Why do we get volcanoes at Constructive Plate Margin

Answer 16

Plates move away from each other
Magma moves up the gap between plates

Question 17

Why do we get Earthquakes at Constructive Plate Margin

Answer 17

As magma moves up it will break or split rocks

Question 18

Do we get volcanoes at constructive plate margin?

Answer 18

Yes

Question 19

Do we get earthquakes at constructive plate margin?

Answer 19

Yes

Question 20

What landform are formed during destructive plate margin?

Answer 20

Ocean trench
Fold mountains

Question 21

Examples of Destructive Plate Margin

Answer 21

Peru Chile Trench

Question 22

Do we get volcanoes in Destructive Plate Margin

Answer 22

Yes

Question 23

Why do we get volcanoes at destructive plate margin?

Answer 23

Oceanic plate subducts and melts. magma is less dense and rises up

Question 24

Do we get Earthquakes at destructive plate margin?

Answer 24

Yes

Question 25

Why do we get earthquakes at destructive plate margin

Answer 25

Pressure exceeds friction when plates slid past

Question 26

What landforms do we get at Collision Plate Margin

Answer 26

Fold Mountains(continental crust buckles and fold upwards)

Question 27

Do we get Volcanoes at collision plate margin? Why?

Answer 27

No
because no subduction
no magma created
no gap from magma to fill

Question 28

Do we get Earthquakes at Collision Plate Margin? Why?

Answer 28

Yes
Due to pressure between plates

Question 29

What Landforms are formed in Conservative Plate Margin

Answer 29

Fault Lines(crack in earth’s crust)

Question 30

Do we get volcanoes in conservative plate margin?

Answer 30

No
No material is melted

Question 31

Do we get earthquakes in Conservative Plate Margin?

Answer 31

Yes
1)Plates stick due to friction
2)pressure builds up
3) Suddenly jolt as each other releasing seismic waves

Question 32

Examples of Conservative Plate Margin

Answer 32

San Andreas Fault
