Which of the following boundaries was formed about 25 million years ago when the Pacific plate met the North American Plate?

Which of the following boundaries was formed about 25 million years ago when the Pacific plate met the North American Plate?

the San Andreas Fault
Viewed from space, the San Andreas Fault looks like a long, narrow valley that marks where the North America plate meets the Pacific plate. This narrow break between the two plates is called a fault.

What type of boundary is created where the Pacific plate meets the North American Plate?

Transform boundaries The San Andreas Fault in California is an active transform boundary. The Pacific Plate (carrying the city of Los Angeles) is moving northwards with respect to the North American Plate.

What happened when the North American Plate collided with the Pacific plate?

Canada’s west coast is situated in one of the world’s most active collision zones. Here, the westbound North American plate overrides the Pacific plate, creating the highly faulted and folded ranges from the Rockies to the Coast Mountains.

What type of plate boundary is found between the Philippine and Pacific plates?

The Philippine Sea Plate. The Philippine Sea plate is tectonically unusual in that almost all the boundaries are convergent. The Pacific plate is subducting beneath the Philippine Sea plate to the east while the west/northwestern part of the Philippine Sea plate is subducting beneath the continental Eurasian plate.

Where does convergent boundary occur?

Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere. The geologic features related to convergent boundaries vary depending on crust types. Plate tectonics is driven by convection cells in the mantle.

What do convergent boundaries form?

Convergent boundaries form strong earthquakes, as well as volcanic mountains or islands, when the sinking oceanic plate melts. The third type is transform boundaries, or boundaries where plates slide past each other, forming strong earthquakes.

What type of plate boundary is the Antarctic Plate and Pacific Plate?

The southern side is a divergent boundary with the Antarctic Plate forming the Pacific–Antarctic Ridge.

What type of plate boundaries exist in the Antarctic and Australian plates?

The southerly side is a divergent boundary with the Antarctic Plate called the Southeast Indian Ridge (SEIR). The subducting boundary through Indonesia is not parallel to the biogeographical Wallace line that separates the indigenous fauna of Asia from that of Australasia.

What type of boundary borders the Philippine plate?

convergent boundaries
The plate is bordered mostly by convergent boundaries: To the north, the Philippine Sea Plate meets the Okhotsk Plate at the Nankai Trough.

What plate boundary is formed between Philippine plate and Eurasian Plate?

Between the Philippine Sea Plate and the Eurasian Plate is the Philippine Trench, the East Luzon Trench, and the Manila Trench.

What plate is Antarctic Plate?

The Antarctic Plate is bounded almost entirely by extensional mid-ocean ridge systems….

Antarctic Plate
Type Major
Approximate area 60,900,000 km2 (23,500,000 sq mi)
Movement1 south-west
Speed1 12–14 mm (0.47–0.55 in)/year

What is formed in convergent plate boundary?

If two tectonic plates collide, they form a convergent plate boundary. The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary. When two plates are moving away from each other, we call this a divergent plate boundary.

Where is the boundary between the Pacific and North American plates?

Cabrillo National Monument south of San Diego also lies within the broad zone of deformation between the two plates. The transform plate boundary between the Pacific and North American Plates in western California formed fairly recently.

How often does the Pacific Plate move past California?

Doing some quick math, one can appreciate how dramatically plate-tectonic forces can affect the landscape, even in our lifetimes. The average movement of the Pacific Plate past the North American Plate in California is about 2 inches (5 centimeters) per year.

Where does the Pacific plate slide past the San Andreas Fault?

San Andreas Transform Plate Boundary The Pacific Plate slides north-northwestward past the North American Plate along the San Andreas Transform Plate Boundary. The San Andreas Fault is responsible for most of the movement in western California, causing a sliver of the state to slide past the rest of the continent.

Where are the transform boundaries on the Caribbean Plate?

On the east, the North American Plate is subducting westward, forming volcanoes of the Lesser Antilles Island Arc. Transform boundaries occur on the north and south sides of the Caribbean Plate. The motion on the north is not pure transform; there is some convergence that contributes to uplift of the topography.
