Plate Boundaries Worksheet | PDF - Free Printable

The task involves completing a table about plate boundaries in the context of plate tectonics. The table requires information on three types of plate boundaries: Convergent, Divergent, and Transform. Below is the completed table with explanations for each type:

Completed Table

| Plate Boundary | Sketch | Definition | Real World Example |
|----------------|---------------------------------------------|---------------------------------------------------------------------------|--------------------------------------------|
| 1. Convergent |  | Occurs when two tectonic plates move toward each other, resulting in one plate being subducted beneath the other or both plates colliding. | Himalayas (India-Eurasia collision), Andes Mountains (Nazca Plate subducting under South America) |
| 2. Divergent |  | Occurs when two tectonic plates move away from each other, creating a gap that is filled by magma rising to the surface, forming new crust. | Mid-Atlantic Ridge, East African Rift Valley |
| 3. Transform |  | Occurs when two tectonic plates slide past each other horizontally, resulting in friction and seismic activity. | San Andreas Fault (Pacific Plate sliding past North American Plate) |

Explanation of Each Type of Plate Boundary

#### 1. Convergent Boundary
- Sketch: Two plates moving toward each other.
- Definition: A convergent boundary occurs when two tectonic plates collide. Depending on the types of plates involved (oceanic vs. continental), different outcomes can occur:
- Oceanic-Continental Convergence: The denser oceanic plate subducts beneath the lighter continental plate, forming a deep trench and volcanic arc (e.g., Andes Mountains).
- Oceanic-Oceanic Convergence: One oceanic plate subducts beneath the other, forming a deep ocean trench and volcanic island arc (e.g., Mariana Trench).
- Continental-Continental Convergence: Both plates are too buoyant to subduct, leading to mountain building (e.g., Himalayas).
- Real World Example: The Himalayas were formed by the convergence of the Indian Plate and the Eurasian Plate.

#### 2. Divergent Boundary
- Sketch: Two plates moving away from each other.
- Definition: A divergent boundary occurs when two tectonic plates move apart from each other. Magma rises to fill the gap, solidifying into new crust. This process is responsible for the formation of mid-ocean ridges and rift valleys.
- Real World Example: The Mid-Atlantic Ridge is a classic example of a divergent boundary where the North American Plate and the Eurasian Plate are moving apart, creating new oceanic crust.

#### 3. Transform Boundary
- Sketch: Two plates sliding past each other horizontally.
- Definition: A transform boundary occurs when two tectonic plates slide past each other horizontally. The friction between the plates can cause earthquakes as they stick and then suddenly slip.
- Real World Example: The San Andreas Fault in California is a well-known transform boundary where the Pacific Plate is moving northwest relative to the North American Plate.

| 1. Convergent |  | Occurs when two tectonic plates move toward each other, resulting in one plate being subducted beneath the other or both plates colliding. | Himalayas (India-Eurasia collision), Andes Mountains (Nazca Plate subducting under South America) |
| 2. Divergent |  | Occurs when two tectonic plates move away from each other, creating a gap that is filled by magma rising to the surface, forming new crust. | Mid-Atlantic Ridge, East African Rift Valley |
| 3. Transform |  | Occurs when two tectonic plates slide past each other horizontally, resulting in friction and seismic activity. | San Andreas Fault (Pacific Plate sliding past North American Plate) |
