Plate Tectonics and Geological Features

Understanding Plate Boundaries:

• Transform Boundary: This is a type of plate boundary where two tectonic plates slide horizontally past each other. This movement often results in significant seismic activity, as the friction between the plates builds up stress that is eventually released as earthquakes.
• Divergent Boundary: Plates move away from each other. Magma rises from the mantle to fill the gap, creating new crust.
• Convergent Boundary: Plates move towards each other. This can lead to subduction (one plate sliding beneath another) or collision, forming mountain ranges or volcanic arcs.

Geological Landforms and Phenomena:

• Fault Valley: A valley formed along a fault line, often due to the sinking or subsidence of the land between parallel faults, or the erosion of weaker rock along the fault. It can be associated with faulting and tectonic activity.
• San Andreas Fault: A famous example of a transform fault zone located in California, USA. It marks the boundary between the Pacific Plate and the North American Plate and is responsible for frequent earthquakes in the region.
• Earthquake: A sudden and violent shaking of the ground, typically causing great destruction, as a result of movements within the earth's crust or volcanic action. Earthquakes are a major phenomenon that occurs at all types of plate boundaries, but are particularly frequent and intense at transform and convergent boundaries.
• Landform created by crumbling of rocks: This description broadly refers to features like talus slopes or scree slopes, which are formed by the accumulation of rock debris that has fallen or tumbled down from higher elevations due to weathering and erosion. While not a primary plate boundary feature, it's a result of geological processes.
