A divergent boundary is one of three major types of plate boundaries defined in plate tectonic theory. |
|
Most earthquakes and volcanic eruptions do not strike randomly but occur in specific areas, such as along plate boundaries. |
|
The volcanically active trail-ends are preferentially located near divergent plate boundaries and are rare near convergent boundaries. |
|
The vast majority of earthquakes and volcanic eruptions occur near plate boundaries, but there are some exceptions. |
|
Sluggish seismic events have been recorded before, emanating from the deeper parts of subducting plate boundaries. |
|
Most of the world's active above-sea volcanoes are located near convergent plate boundaries where subduction is occurring, particularly around the Pacific basin. |
|
Igneous rocks associated with convergent plate boundaries have the greatest diversity. |
|
The volume of magma produced is minor in comparison to that generated at oceanic rises and at convergent plate boundaries. |
|
Limestone islands also rise from forearc zones along convergent plate boundaries. |
|
Convergent plate boundaries are formed where one plate dives under another. |
|
The big arrows show the direction of overall plate motion, the smaller arrows show relative motion across plate boundaries. |
|
Tectonic plate boundaries, rift valleys and horst-and-graben systems are common geological phenomena in global terms. |
|
The mechanics of mountain belts along convergent plate boundaries are often considered to be analogous to that of a wedge of snow or soil in front of moving bulldozer. |
|
Global heat-flow maps constructed from geophysical data show that the zones of highest heat flow occur along the active plate boundaries. |
|
Students can also explore plate boundaries in this activity by 3D Geography. |
|
Modern plate boundaries may be far different from ancient ones presumably marked by old fold belts. |
|
Elastic deformation of the earthquake cycle is limited to a zone several 100 km wide close to the plate boundaries. |
|
Large vertical movements of the earth's crust can occur at plate boundaries. |
|
Australia is located entirely on one plate, as is the Antarctic, but the other continents have plate boundaries running through them. |

|
|
The French metropolitan territory is faraway from the high deformation zones which on a global scale are represented by the plate boundaries. |
|
The Earth is continuously recycling its crust, producing new crust at some plate boundaries while destroying old crust at other plate boundaries. |
|
In a written report, describe the relationships among plate boundaries, mountain building, and trenches. |
|
This map of earthquake epicenters around the world shows a very close correlation with the location of plate boundaries. |
|
The scope of structural geology is vast, ranging in size from submicroscopic lattice defects in crystals to mountain belts and plate boundaries. |
|
Earthquake sources are concentrated along the oceanic ridges, which correspond to divergent plate boundaries. |
|
The Ottawa-Gatineau region is located far from active tectonic plate boundaries, the usual source of earthquakes, but it does have a seismic history. |
|
Transform faults are also referred to as conservative plate boundaries, as lithosphere is neither created nor destroyed. |
|
Passive margins are only passive in that they are not active plate boundaries. |
|
Volcanic high islands are also numerous around convergent plate boundaries, particularly where active subduction occurred during the Late Quaternary. |
|
Black smokers, located along some plate boundaries in the ocean, are responsible for the formation of mineral deposits, and have been for billions of years. |
|
Volcanism away from plate boundaries has also been explained as mantle plumes. |
|
Long linear regions of geologic features are explained as plate boundaries. |
|
Earthquakes are rare because Florida is not located near any tectonic plate boundaries. |
|
Three types of plate boundaries exist, with a fourth, mixed type, characterized by the way the plates move relative to each other. |
|
Many of the ancient faults are within plates rather than along plate boundaries. |
|
Oceanic crust, the outermost layer of Earth's lithosphere that is found under the oceans and formed at spreading centres on oceanic ridges, which occur at divergent plate boundaries. |
|
Subduction zones exist at convergent plate boundaries where one plate of oceanic lithosphere converges with another plate. |
|
Major mountains tend to occur in long linear arcs, indicating tectonic plate boundaries and activity. |
|
Past plate boundaries within existing plates are identified from a variety of evidence, such as the presence of ophiolites that are indicative of vanished oceans. |
|
|
The majority of the world's active volcanoes occur along plate boundaries, with the Pacific Plate's Ring of Fire being the most active and widely known today. |
|
New England and Long Island are far from the nearest tectonic plate boundaries, which are far out in the Atlantic Ocean and the Caribbean Sea, the USGS reports. |
