Describe the tectonic setting for the following by filling in the columns below, using the figure as a reference

Transcribed Image Text:**Figure 2.1 Earth's Major Lithospheric Plates**
The map illustrates Earth's major lithospheric plates, including:
- **North American Plate**
- **Caribbean Plate**
- **South American Plate**
- **Nazca Plate**
- **Scotia Plate**
- **African Plate**
- **Eurasian Plate**
- **Arabian Plate**
- **Australian-Indian Plate**
- **Antarctic Plate**
- **Pacific Plate**
- **Philippine Plate**
- **Cocos Plate**
- **Juan de Fuca Plate**
Key geological features on the map include the Mid-Atlantic Ridge, East Pacific Rise, Galapagos Ridge, Chile Ridge, Southwest Indian Ridge, Southeast Indian Ridge, and Mid Indian Ridge.
**Boundary Types:**
- **Convergent Plate Boundary (A)**
- Illustrated with a subduction zone.
- Oceanic crust is forced below the continental lithosphere forming a trench and volcanic arcs due to melting in the asthenosphere.
- **Transform Plate Boundary (B)**
- Plates slide horizontally past one another.
- **Divergent Plate Boundary (C)**
- Situated at a spreading center.
- Oceanic lithosphere is created; magma rises and solidifies to form new crust.
**Boundary Indicators:**
- Red Line: Divergent
- Blue Line: Convergent
- Yellow Line: Transform
Note: The map does not show many smaller plates. Each boundary type is further illustrated with block diagrams showing tectonic interactions.

Transcribed Image Text:The table below outlines various geological areas, the types of tectonic plates involved, the active geological processes, and the boundary types.
| Area | Type of Plate(s) | Active Processes | Boundary Type |
|----------------------|------------------|------------------|---------------|
| Himalayas | | | |
| Aleutian Islands | | | |
| Andes | | | |
| San Andreas Fault | | | |
| Iceland | | | |
This table serves as a framework for understanding the complex interactions of tectonic plates and their influence on Earth's geology. Each area listed is known for specific geological activity due to the nature of the tectonic plates and boundaries present.
