East

Forms

  1. The fracture zone that forms a transform plate boundary is known as a transform fault. (Web site)

Part

  1. Usually only two arms of any given three-armed graben become part of a divergent plate boundary. (Web site)
  2. Part 5 looks at the changes along a convergent plate boundary where the subducting slab has a finite length in that third dimension along the boundary.

Region

  1. There is no evidence of a plate boundary in the region at that time.

Active

  1. Because the island lies on an active plate boundary, earthquakes are a constant threat, and the densely populated coastal areas are vulnerable to tsunamis. (Web site)
  2. Although the islands are not near a plate boundary, they are seismically and volcanically very active. (Web site)

Shows

  1. It brings you to a plate boundary and shows you some geomorphologic features typical of a transform fault. (Web site)

Point

  1. The point where two or more plates meet is known as a plate boundary. (Web site)

Stress

  1. This builds up stress in the rocks at the plate boundary. (Web site)

Ocean

  1. Most of these occur at the diverging plate boundary that runs north-south through the ocean.
  2. An accretionary wedge is a mass of ocean and rock material that is scraped off of the subducting plate at a convergent plate boundary. (Web site)

Source

  1. Or the source of the strain may be a long distance away, at a plate boundary.

Movement

  1. The committee predicts that the quake would be caused by movement at the plate boundary, where the Pacific and terrestrial plates meet. (Web site)

Places

  1. In some places, two plates move apart from each other; this is called a diverging plate boundary. (Web site)
  2. In few places can one see a plate boundary better exposed than in Iceland atop the mid- Atlantic ridge.

Shape

  1. The resulting volcano chain has the shape of an arc parallel to the convergent plate boundary and convex toward the subducting plate. (Web site)

West Coast

  1. Troubled Times South American Plate - The South American plate is about 1 3 land mass with a convergent plate boundary on the west coast.

South America

  1. Also the plate boundary between Africa and South America (note that it has the same shape as the coastlines in these countries). (Web site)
  2. South America and Africa were once together, but were split apart by the formation of a diverging plate boundary. (Web site)
  3. It is located about 2000 miles from the plate boundary on the west coast of South America.

North American

  1. Heubech, C. and Mann, P., 1991. Geologic evaluation of plate kinematic models for the North American - Caribbean plate boundary zone.

Oblique

  1. In most zones of continent-continent collision the relative movement of the plates is oblique to the plate boundary itself.
  2. In contrast, the subducted plate boundary lies east of and oblique to the Northern Colima and Central Colima grabens. (Web site)

Three

  1. The interaction of the three major plates creates a complex tectonic especially in the plate boundary that is situated in Eastern Indonesia. (Web site)
  2. Plate boundary zones occur in more complex situations where three or more plates meet and exhibit a mixture of the above three boundary types. (Web site)

Type

  1. The type of friction created may be due to the characteristic of the geologic fault or the plate boundary as follows.
  2. The distinguishing characteristic of a transform fault is that both ends extend to a junction with another type of plate boundary. (Web site)

Slip

  1. The new research indicates the tremor is at the plate boundary, in essentially the same place as the slip. (Web site)

California

  1. California is famous for earthquakes along the San Andreas Fault zone but there is another type of plate boundary where large earthquakes occur.

Northern California

  1. Before it became a transform fault boundary, the plate boundary along northern California was a convergent boundary. (Web site)

Second Type

  1. The offsets occur on transform faults, which form the second type of plate boundary.

Earth

  1. In general you don't want to live near a plate boundary as the earth is active there. (Web site)
  2. This image shows a slice through the Earth at a convergent plate boundary.

Lithosphere

  1. It is thought that convection currents in the Earth 's mantle rise to the base of the lithosphere where the divergent plate boundary exists. (Web site)

Volcanoes

  1. This chain of volcanoes is called a volcanic arc, and it is usually a few hundred miles inland from the plate boundary.
  2. These volcanoes are often created along the plate boundary and their tops appear as a line of islands. (Web site)
  3. This is the actual plate boundary, and is where most of the earthquakes and volcanoes take place.

Ocean Floor

  1. Most transform faults are found on the ocean floor, where they often offset active spreading ridges to form a zigzag plate boundary. (Web site)
  2. Most transform boundaries are found on the ocean floor, where they often offset active spreading ridges to form a zigzag plate boundary. (Web site)

Opposite Directions

  1. The two sides move away in opposite directions, creating a divergent plate boundary. (Web site)

Subduction Zone

  1. This leads us to the second type of plate boundary, which is called a convergent boundary or subduction zone. (Web site)
  2. It occurs when an oceanic ridge (spreading plate boundary) crosses a subduction zone.

Magma

  1. Hot spot volcano: A volcano formed by a rising plume of magma that is not located at a plate boundary. (Web site)

Oceanic Crust

  1. A divergent plate boundary between two slabs of oceanic crust is generally referred to as a spreading center or spreading ridge. (Web site)

Mantle

  1. At a divergent plate boundary, the spreading crust forms channels through which magma rises from the mantle.
  2. As it descends and dips into the mantle, creating a trench at the plate boundary on the ocean floor, it heats as well. (Web site)

Continental Crust

  1. It also depends on whether the lithosphere on the two sides of the plate boundary is oceanic crust, continental crust, or one piece of each type.
  2. PLATES ARE CREATED: In the diagram below you can see that the continental crust is beginning to separate creating a diverging plate boundary. (Web site)
  3. Obduction is the overthrusting of continental crust by oceanic crust or mantle rocks at a destructive plate boundary.

Oceanic

  1. The plate boundary between oceanic and continental plates is also shown.
  2. Subduction zones are one type of convergent plate boundary where either an oceanic or a continental plate overrides an oceanic plate. (Web site)
