The task involves identifying the main types of tectonic plate movements and describing what is happening in each scenario. Below is the solution with explanations for each image:
---
Image 1:
-
Movement Type: Divergent Plate Boundary
-
Description: The two plates are moving away from each other. This type of movement typically occurs at mid-ocean ridges or rift zones on land. As the plates separate, magma rises to fill the gap, creating new crust. Examples include the Mid-Atlantic Ridge.
---
Image 2:
-
Movement Type: Convergent Plate Boundary (Subduction Zone)
-
Description: One plate is moving beneath another plate, a process called subduction. This typically happens when an oceanic plate meets a continental plate or another oceanic plate. The denser oceanic plate sinks into the mantle, forming a deep trench. Examples include the Andes Mountains and the Mariana Trench.
---
Image 3:
-
Movement Type: Transform Fault Boundary
-
Description: The two plates are sliding past each other horizontally. There is no creation or destruction of crust in this type of boundary. Instead, stress builds up along the fault line, often leading to earthquakes. A classic example is the San Andreas Fault in California.
---
Image 4:
-
Movement Type: Convergent Plate Boundary (Collision Zone)
-
Description: Two continental plates collide with each other. Since neither plate can sink due to their similar densities, they push against each other, causing folding and uplifting of the crust. This results in the formation of mountain ranges. Examples include the Himalayas and the Alps.

Final Answer:
| Image | Movement Type | Description |
|-------|---------------|-------------|
| 1 | Divergent Plate Boundary | Plates are moving apart, creating new crust as magma rises to fill the gap. |
| 2 | Convergent Plate Boundary (Subduction Zone) | One plate is subducting beneath another, forming a deep trench. |
| 3 | Transform Fault Boundary | Plates are sliding horizontally past each other, often resulting in earthquakes. |
| 4 | Convergent Plate Boundary (Collision Zone) | Two continental plates collide, causing uplift and the formation of mountains. |
