Plate Boundary Worksheet Solution and Explanation
####
Part 1: Label Each Figure by Writing the Type of Plate Boundary It Shows
We need to identify the type of plate boundary shown in each figure.
1.
Figure 1:
- The two plates are moving apart from each other, creating a gap or rift.
-
Type of Boundary:
Divergent Boundary
2.
Figure 2:
- One plate is subducting (sinking) beneath another plate, forming a deep trench.
-
Type of Boundary:
Convergent Boundary (Subduction Zone)
3.
Figure 3:
- The two plates are sliding past each other horizontally without any significant vertical movement.
-
Type of Boundary:
Transform Boundary

Part 2: Answer the Questions About Plate Boundaries
4.
What type of boundary/boundaries create(s) new seafloor?
- New seafloor is created when two tectonic plates move apart, allowing magma to rise and solidify at the surface.
-
Answer:
Divergent Boundary
5.
What type of boundary/boundaries can create earthquakes?
- Earthquakes occur along all types of plate boundaries due to the friction and stress between the plates.
- However, they are most common and intense at convergent and transform boundaries.
-
Answer:
Convergent and Transform Boundaries
6.
Which type of boundary/boundaries create mountain ranges?
- Mountain ranges are typically formed when two continental plates collide at a convergent boundary, causing the crust to buckle and fold upward.
-
Answer:
Convergent Boundary

Part 3: Complete the Concept Map
The concept map requires us to match terms with the appropriate plate boundary types. Let’s fill in the blanks step by step.
#####
Concept Map Structure:
-
Plate Boundaries → Include:
-
Convergent
-
Divergent
-
Transform
-
Convergent Boundaries:
- Form:
Deep-sea trenches,
Volcanic islands,
Volcanic mountains,
Major earthquakes
-
Divergent Boundaries:
- Form:
Mid-ocean ridges,
Rift valleys
-
Transform Boundaries:
- Cause:
Major earthquakes
#####
Filling in the Blanks:
1.
Convergent Boundaries:
- Form:
Deep-sea trenches,
Volcanic islands,
Volcanic mountains,
Major earthquakes
- These features are associated with the collision or subduction of plates.
2.
Divergent Boundaries:
- Form:
Mid-ocean ridges,
Rift valleys
- These features are associated with the separation of plates.
3.
Transform Boundaries:
- Cause:
Major earthquakes
- Transform boundaries are primarily known for generating earthquakes due to the horizontal sliding of plates.
