Let's solve this step-by-step based on the image you've described, which shows
four diagrams of tectonic plate movements. The task is to:
1.
Label the main type of movement (e.g., convergent, divergent, transform).
2.
Describe what is happening to the two tectonic plates.
---
🔹 Diagram 1:
Image: Two plates moving
toward each other, with a mountain-like uplift in the middle.
-
✔ Type of Movement:
Convergent boundary (specifically,
continental-continental convergence)
-
✔ Description: Two continental plates are colliding. Since neither plate is dense enough to subduct (sink), they crumple and fold, forming
mountain ranges (like the Himalayas).
---
🔹 Diagram 2:
Image: Two plates moving
toward each other, but one is bending downward beneath the other.
-
✔ Type of Movement:
Convergent boundary (specifically,
oceanic-continental convergence)
-
✔ Description: An oceanic plate is subducting (sinking) beneath a continental plate. This creates a
deep ocean trench and can lead to
volcanic activity and earthquakes as the subducted plate melts and magma rises.
---
🔹 Diagram 3:
Image: Two plates moving
horizontally past each other, with arrows pointing in opposite directions.
-
✔ Type of Movement:
Transform boundary
-
✔ Description: The plates are sliding horizontally past each other. There is
no creation or destruction of crust. This movement can cause
earthquakes due to friction and stress buildup (e.g., San Andreas Fault).
---
🔹 Diagram 4:
Image: Two plates moving
away from each other, with arrows pointing outward.
-
✔ Type of Movement:
Divergent boundary
-
✔ Description: The plates are pulling apart, creating a
mid-ocean ridge or rift valley. Magma rises from below to fill the gap, forming new crust (e.g., Mid-Atlantic Ridge).
---
✔ Final Answer Summary:
| Diagram | Type of Movement | Description |
|--------|--------------------------|-----------|
| 1 | Convergent (Continental-Continental) | Plates collide, crumple, form mountains |
| 2 | Convergent (Oceanic-Continental) | Oceanic plate subducts under continental plate; trench and volcanoes form |
| 3 | Transform | Plates slide past each other; causes earthquakes |
| 4 | Divergent | Plates move apart; new crust forms |
---
You can now fill in the worksheet like this:
1.
Convergent Boundary (Continental-Continental)
→ Two continental plates collide and push upward, forming mountain ranges.
2.
Convergent Boundary (Oceanic-Continental)
→ Oceanic plate subducts beneath continental plate, causing deep trenches and volcanic activity.
3.
Transform Boundary
→ Plates slide horizontally past each other, often causing earthquakes.
4.
Divergent Boundary
→ Plates move apart, allowing magma to rise and create new crust.
