1/8/2023 0 Comments Transform plate boundary![]() ![]() Geologists predict that another severe quake must occur in Southern California sometime in the next quarter-century or so the stress is just building up too much. Major earthquakes occur along the San Andreas Fault every few decades. The most common one is the San Andreas Fault it’s the longest highly active transform boundary on the surface of the Earth. Such boundaries are inevitable whenever you have a sphere that’s broken into divergent and convergent boundaries. Transform boundaries are faults where two plates slide by each other. This is a transcript from the video series The Joy of Science. ![]() It’s hotter-temperatures are typically over 1,000 degrees-and that’s hot enough to make the rock relatively soft and plastic more like a taffy. This asthenosphere layer extends deep into the mantle. It overlies on top of a softer layer, the soft, hot asthenosphere. This strong rock layer is the lithosphere. That is, if you take a hammer and hit it, it will shatter it will break, like a brittle piece of ceramic. It’s also relatively cold, less than 1,000 degrees centigrade, and at those temperatures, the rock is brittle. The lithosphere includes the crust and the very top part of the mantle it’s a relatively thin layer, about 50 to 100 kilometers thick. The lithosphere and the asthenosphere are the two great layers associated with plate tectonics.
