SOLVED: Geologic Processes. Activity 2 Geologic Processes ... - Free Printable

Problem Overview:

The task involves analyzing the geological processes along plate boundaries and labeling them based on their types: Convergent, Divergent, and Transform. Additionally, you need to answer guide questions about each type of boundary, including the motion of the plates, whether the process is constructive or destructive, and the landforms associated with each type.

Step 1: Labeling the Plate Boundaries

The image shows five labeled areas (1, 2, 3, 4, 5). Based on the arrows and the context of plate tectonics, we can identify the types of plate boundaries:

1. Area 1: The arrows are pointing toward each other, indicating that two plates are moving toward one another. This is a Convergent Boundary.
2. Area 2: The arrows are pointing away from each other, indicating that two plates are moving apart. This is a Divergent Boundary.
3. Area 3: Similar to Area 2, the arrows are pointing away from each other, indicating another Divergent Boundary.
4. Area 4: The arrows are pointing toward each other, indicating that two plates are moving toward one another. This is a Convergent Boundary.
5. Area 5: The arrows are pointing in opposite directions along a single line, indicating that two plates are sliding past each other. This is a Transform Boundary.

Step 2: Answering the Guide Questions

Now, let's address the guide questions for each type of plate boundary.

#### Convergent Boundary
1. What is the motion of the plates in this type of boundary?
- The plates move toward each other.

2. Is it constructive or destructive? Why?
- It is destructive because the collision of plates leads to the destruction of crustal material. One plate may be subducted beneath the other, causing the destruction of oceanic crust.

3. What are the landforms associated with this type of boundary? And explain how it is produced.
- Landforms: Mountain ranges, trenches, volcanic arcs, and island arcs.
- Explanation: When two continental plates collide, they push up the crust, forming mountain ranges (e.g., the Himalayas). When an oceanic plate collides with a continental plate, the denser oceanic plate is subducted beneath the continental plate, forming a deep ocean trench and volcanic activity above the subduction zone (e.g., the Andes Mountains).

#### Divergent Boundary
1. What is the motion of the plates in this type of boundary?
- The plates move away from each other.

2. Is it constructive or destructive? Why?
- It is constructive because new crust is formed as magma rises to fill the gap created by the separation of the plates.

3. What are the landforms associated with this type of boundary? And explain how it is produced.
- Landforms: Mid-ocean ridges, rift valleys, and new ocean basins.
- Explanation: At divergent boundaries, magma rises to the surface, creating new crust. In the ocean, this forms mid-ocean ridges (e.g., the Mid-Atlantic Ridge). On land, it can create rift valleys (e.g., the East African Rift Valley) as the crust pulls apart.

#### Transform Boundary
1. What is the motion of the plates in this type of boundary?
- The plates move horizontally past each other.

2. Is it constructive or destructive? Why?
- It is neither constructive nor destructive because no new crust is formed, and no crust is destroyed. Instead, the plates slide past each other, releasing energy in the form of earthquakes.

3. What are the landforms associated with this type of boundary? And explain how it is produced.
- Landforms: Fault lines, earthquake zones.
- Explanation: Transform boundaries are characterized by fault lines where the plates grind against each other. This movement often results in frequent earthquakes (e.g., the San Andreas Fault in California).

| Convergent | Plates move toward each other. | Destructive; one plate is subducted beneath the other. | Mountain ranges, trenches, volcanic arcs, and island arcs. New crust is destroyed during subduction. |
| Divergent | Plates move away from each other. | Constructive; new crust is formed as magma rises. | Mid-ocean ridges, rift valleys, and new ocean basins. Magma fills the gap between separating plates. |
| Transform | Plates move horizontally past each other. | Neither constructive nor destructive; no crust is formed or destroyed. | Fault lines, earthquake zones. Energy is released as plates grind against each other. |
