Step-by-step solution for: Plate tectonics - Ms. Sadler 8th grade science
To solve the problem presented in the image, we need to identify and describe the types of plate boundaries and the associated earthquake fault features. The task involves matching the diagrams with their corresponding descriptions and identifying the type of boundary (divergent, convergent, or transform) for each.
#### 1. Understanding Plate Boundaries:
There are three main types of plate boundaries:
- Divergent Boundary: Plates move apart from each other.
- Convergent Boundary: Plates move toward each other.
- Transform Boundary: Plates slide past each other horizontally.
#### 2. Analyzing Each Diagram:
##### Diagram 1:
- Description: Two plates moving away from each other.
- Type of Boundary: Divergent Boundary.
- Earthquake Fault Feature: Normal Fault.
- Explanation: At a divergent boundary, tension causes normal faults where one block drops relative to the other.
##### Diagram 2:
- Description: Two plates moving toward each other, with one plate subducting beneath the other.
- Type of Boundary: Convergent Boundary (Subduction Zone).
- Earthquake Fault Feature: Reverse Fault.
- Explanation: At a convergent boundary, compression causes reverse faults where one block is pushed up over another.
##### Diagram 3:
- Description: Two plates sliding past each other horizontally.
- Type of Boundary: Transform Boundary.
- Earthquake Fault Feature: Strike-Slip Fault.
- Explanation: At a transform boundary, the movement is primarily horizontal, resulting in strike-slip faults where blocks move side by side.
##### Diagram 4:
- Description: Two plates moving away from each other, creating a rift valley.
- Type of Boundary: Divergent Boundary.
- Earthquake Fault Feature: Normal Fault.
- Explanation: Similar to Diagram 1, this is another example of a divergent boundary where normal faults occur due to tension.
##### Diagram 5:
- Description: Two plates moving toward each other, colliding without subduction.
- Type of Boundary: Convergent Boundary (Collision Zone).
- Earthquake Fault Feature: Thrust Fault.
- Explanation: At a collision zone, thrust faults occur where one block is pushed up over another due to compressional forces.
##### Diagram 6:
- Description: Two plates sliding past each other horizontally.
- Type of Boundary: Transform Boundary.
- Earthquake Fault Feature: Strike-Slip Fault.
- Explanation: Similar to Diagram 3, this is another example of a transform boundary where strike-slip faults occur due to horizontal movement.
#### 3. Filling in the Table:
| Diagram | Type of Boundary | Earthquake Fault Feature |
|---------|------------------|--------------------------|
| 1 | Divergent | Normal Fault |
| 2 | Convergent | Reverse Fault |
| 3 | Transform | Strike-Slip Fault |
| 4 | Divergent | Normal Fault |
| 5 | Convergent | Thrust Fault |
| 6 | Transform | Strike-Slip Fault |
\[
\boxed{
\begin{array}{|c|c|c|}
\hline
\text{Diagram} & \text{Type of Boundary} & \text{Earthquake Fault Feature} \\
\hline
1 & \text{Divergent} & \text{Normal Fault} \\

2 & \text{Convergent} & \text{Reverse Fault} \\
