Divergent boundaries are spreading boundaries, where new oceanic crust is created from magma derived from partial melting of the mantle caused by decompression as hot mantle rock from depth is moved toward the surface (Figure \(\PageIndex{3}\)). Thisblock of crust is rotated west and pushed north into Washington state. This plate is small. The subducted lithosphere descends into the hot mantle at a relatively shallow angle close to the subduction zone, but at steeper angles farther down (up to about 45). Filipino plate: This plate includes the islands that make up the Philipines and north to include parts of southern Japan.

Sediment that has accumulated on the continental slope is thrust up into an accretionary wedge, and compression leads to thrusting within the continental plate (Figure \(\PageIndex{7}\)). [citation needed], The southern side is a divergent boundary with the Antarctic Plate forming the PacificAntarctic Ridge. This reduced the Farallon Plate to a few remnants along the west coast of North America and the Phoenix Plate to a small remnant near the Drake Passage, and destroyed the Izanagi Plate by subduction under Asia.
At present, North and South America, Europe, and Africa are moving with their respective portions of the Atlantic Ocean.

The colliding continental material will not be subducted because it is too light (i.e., because it is composed largely of light continental rocks [SIAL]), but the root of the oceanic plate will eventually break off and sink into the mantle. WebIn what direction is the Pacific Plate moving? Note that the hotspot is not at a plate boundary. Eurasia plate, Pacific plate. Heezen and Marie Tharp, Copyright 1977.) What direction has the pacific plate been moving since the formation of Daikakuji? Examples of ocean-continent convergent boundaries are subduction of the Nazca Plate under South America (which has created the Andes Range) and subduction of the Juan de Fuca Plate under North America (creating the mountains Garibaldi, Baker, St. Helens, Rainier, Hood, and Shasta, collectively known as the Cascade Range). Once this happens, the continents will no longer continue to move apart because the spreading at the mid-Atlantic ridge will be taken up by subduction. [2] The plate first came into existence 190 million years ago, at the triple junction between the (Note that spreading rates are typically double the velocities of the two plates moving away from a ridge.). A sharp bend in the chain indicates that the motion of the Pacific Plate abruptly changed about 43 million years ago, as it took a more westerly turn from its earlier northerly direction. The Pacific Plate is the fastest, followed by the Australian and Nazca Plates. It runs along the north western coast of the United States and the southern British Columbia coast.

It is assumed that the relative lack of strength of the partial melting zone facilitates the sliding of the lithospheric plates. 
The Pacific Plate is being moved north west due to sea floor spreading from the East Pacific Rise (divergent margin) in the Gulf of California. The Pacific Plate subsequently grew to where it underlies most of the Pacific Ocean basin. 
Required fields are marked *, Pacific Plate: Movement and Direction of the Pacific Tectonic Boundary. Imagine that your left hand is the undeformed Pacific Plate, your right hand the intact North American Plate. Its motion is not smooth, but rather sticky; strain builds up until the fault breaks and a few meters of Juan De Fuca slips under North America in a big Megathrust earthquake. There are two kinds of plates oceanic and continental plates. earthquakes: earthquakes occur on the boundaries of the plates as they rub past each other. This map of gravity residuals measured over the puget lowland reveals a pattern of deep, fault bounded basins (cool colors) and uplifts (warm colors). Remember that the hotspot remains in the same location and the lithosphere moves over it (as shown in the Hot Spot video). Along much of the boundary, the bulk of the motion occurs along the San Andreas Fault. As these two plates pull apart from each other, it forms new oceanic crust. The San Andreas Fault is just one of many active earthquake faults in a broad zone of shearing along the transform plate boundary in the San Francisco Bay Area. This plate is rotating in a clockwise direction towards the Pacific plate. This situation may not continue for too much longer, however. The San Andreas Fault and Queen Charlotte Fault are transform plate boundaries developing where the Pacific Plate moves northward past the North American Plate.
