Constructive Plate Boundaries
What is a Conservative Plate Boundary?
- This is a plate boundary where two plates slide past each other, they may be travelling in the same or different directions, and tend to travel at different speeds
- Friction can build up between the two plates, causing a sudden slip, this movement will create shock waves, which can contribute to a shallow focused earthquake occurring, as a huge amount of energy has been produced and needs to be released
- A fault line is created along the meeting point of the two plates
The San Andreas Fault
- The San Andreas fault is arguably the most well known conservative plate boundary
- It is located on the West coast of America, where the Pacific Plate meet the North American Plate
- The Plates are both moving in a Northerly direction, but at different speeds, which has resulted in the formation of the San Andreas Fault line, the pacific Plate is moving at around 6cm a year, while the North American Plate is only moving 1cm a year
- The San Andreas fault line runs roughly 800 miles through western and southern California
