|
Sides of plates are rocky and jagged, which holds the plates together.
|
|
|
When forces push them to move, earthquakes can occur, such as on the San Andreas fault in California.
|

|
Where pieces of Earth’s crust diverge on land, a rift valley occurs.
|

|
When 2 oceanic plates converge, the more dense plate sinks below the less dense plate.

Detailed explanation-1: -Transform boundary earthquakes are shallow and occur within 12 miles of the surface. Earthquakes happen from the movement of Earth’s crust along transform and strike-slip faults. Other changes with this kind of plate movement include large displacement of rock and broad zones of Earth’s deformed crust.
Detailed explanation-2: -The 1, 200-kilometer-long San Andreas fault zone is part of the boundary between the Pacific and North American plates, and thus is known as a transform fault. It connects the East Pacific Rise in the Gulf of California with the junction of the Mendocino fracture zone and the Cascade subduction zone to the north.
Detailed explanation-3: -Tectonic Plate Boundaries The Pacific Plate (on the west) slides horizontally northwestward relative to the North American Plate (on the east), causing earthquakes along the San Andreas and associated faults. The San Andreas fault is a transform plate boundary, accomodating horizontal relative motions.
Detailed explanation-4: -Plates can move past each other in the same plane at a boundary. This type of boundary is called a transform boundary. This type of boundary is dominated by strike-slip faulting, although other types of faulting may be observed. Where two plates slide past each other, earthquakes originate at shallow depths.
Detailed explanation-5: -This is because the plates slide past each other without moving up or down. The San Andreas Fault that runs through much of California is an enormous transform plate boundary. It is the plate boundary between Pacific and North American plates. The deadliest earthquake on the San Andreas Fault occurred in 1906.
